I found this phenomenon, and it can be reproduced stably. If I use a triple-camera to take a photo, if the picture is moving, or I move the phone, let's assume it moves horizontally, when I aim at an object, I press the shutter, which is called time T. At this time, the picture in the viewfinder is T0, and the photo produced is about T+100ms. If I use a single-camera to take a photo, use the same speed to move the phone to move the picture, and press the shutter when aiming at the same object, the photo produced is about T+400ms later. Let me describe the problem I encountered in another way. Suppose a pile of cards are placed horizontally on the table, and the cards are written with numbers from left to right, 0,1,2,3,4,5,6... Now aim the camera at the number 0, and then move to the right at a uniform speed. The numbers pass through the camera's viewfinder and continue to increase. When aiming at the number 5, press the shutter. If it is a triple-camera, the photo obtained will probably show 6, while if it is taken with a single-camera, the photo obtained will be about 9. This means the triple camera can capture photos faster, but why is this the case? Any explanation?

I tried stacking 30 RAW exposures of 1 second each, but the quality is far inferior to the 30-second long exposure in night mode.

Hello, I m trying to implement deferred photo processing in my photo capture app. After I take a photo, I pass it through a CIFilter, now with the Deferred Photo Processing where would I pass the resulting photo through the CIFilter? Since there is no way for me to know when the system has finished processing a photo. If I have to do it in my app foreground every time, how do I prevent a scenario, where the user takes a photo, heads straight to the Photos App and sees the image without the filter?

Hi, I'm having difficulties figuring out how I can reliably detect if the macOS system PHPhotoLibrary is available. If I place the system Photo Library on an external drive and then eject it, other apps on startup, such as Photos, will tell me that the library isn't available. How can I replicate this behavior? The only API I can find for this detection on startup is "PHPhotoLibrary.shared().unavailabilityReason". However this always returns nil. Another strange behavior is if I register a PHPhotoLibraryAvailabilityObserver class on startup when the library is available and then eject the drive, I do get a notification via photoLibraryDidBecomeUnavailable, but then directly after the call the app is terminated. This prevents the app to perform any kind of graceful termination. Is this the expected behavior? It would make sense that it's up to the developer to decide what happens if the library becomes unavailable. Thanks

In the docs it looks like something allows you to set a background replacement image in the Control Center controls (like on a Mac). However, I can't find any documentation on it, beyond this reference in the Apple docs. https://developer.apple.com/documentation/avfoundation/avcapturedevice/isbackgroundreplacementactive?language=objc Does anyone have any advice to enable backgrounds in the camera system wide?

There seems to be an issue in iOS 18 / macOS 15 related to image thumbnail generation and/or HEIC. We are transcoding JPEG images to HEIC when they are loaded into our app (HEIC has a much lower memory footprint when loaded by Core Image, for some reason). We use Image I/O for that: guard let source = CGImageSourceCreateWithURL(inputURL, nil), let destination = CGImageDestinationCreateWithURL(outputURL, UTType.heic.identifier as CFString, 1, nil) else { throw <error> } let primaryImageIndex = CGImageSourceGetPrimaryImageIndex(source) CGImageDestinationAddImageFromSource(destination, source, primaryImageIndex, nil) When we use CGImageDestinationAddImageFromSource, we get the following warnings on the console: createImage:1445: *** ERROR: bad image size (0 x 0) rb: 0 CGImageSourceCreateThumbnailAtIndex:5195: *** ERROR: CGImageSourceCreateThumbnailAtIndex[0] - 'HJPG' - failed to create thumbnail [-67] {alw:-1, abs: 1 tra:-1 max:4620} writeImageAtIndex:1025: ⭕️ ERROR: '<app>' is trying to save an opaque image (4620x3466) with 'AlphaPremulLast'. This would unnecessarily increase the file size and will double (!!!) the required memory when decoding the image --> ignoring alpha. It seems that CGImageDestinationAddImageFromSource is trying to extract/create a thumbnail, which fails somehow. I re-wrote the last part like this: guard let primaryImage = CGImageSourceCreateImageAtIndex(source, primaryImageIndex, nil), let properties = CGImageSourceCopyPropertiesAtIndex(source, primaryImageIndex, nil) else { throw <error> } CGImageDestinationAddImage(destination, primaryImage, properties) This doesn't cause any warnings. An issue that might be related has been reported here. I've also heard from others having issues with CGImageSourceCreateThumbnailAtIndex.

Hello Developers, I am working on an app where I need to capture 48MP high-resolution photos using the ultra-wide camera of the iPhone 16 Pro while an AR session is running. The goal is to take these photos without interrupting or impacting the AR session, which uses the main wide-angle camera. Despite extensive testing and various approaches, we have been unable to achieve the desired functionality. What We Have Tried So Far 1. Using AVCaptureMultiCamSession: • We attempted to leverage AVCaptureMultiCamSession to simultaneously use the wide-angle camera for ARKit and the ultra-wide camera for photo capture. • However, this approach resulted in resource conflicts, with errors such as Cannot Record (OSStatus error -16409) and dropped frames. Additionally, the ultra-wide camera feed would frequently freeze or stop. 2. Dedicated AVCaptureSession for the Ultra-Wide Camera: • We separated the ultra-wide camera into its own AVCaptureSession while letting ARKit exclusively use the wide-angle camera. • This setup showed initial promise, but the ultra-wide camera feed would still stop running after a very short time (under one second). • Debugging logs indicated potential system-level interruptions, possibly due to resource prioritization by iOS. 3. Notification-Based Monitoring: • We implemented monitoring for session interruptions (AVCaptureSession.wasInterruptedNotification), but this provided limited insights into the exact cause of the session stopping. • We suspect iOS is de-prioritizing the ultra-wide camera session due to resource management policies or conflicts with ARKit. 4. Adjusting Camera Configurations: • We attempted to simplify both ARKit and AVCaptureSession configurations by reducing features like depth data and by using lower session presets for video capture. However, the core issue persisted. The Core Problem • The ultra-wide camera session frequently stops or freezes when used alongside ARKit. • Capturing high-resolution 48MP photos during the AR session is critical to the functionality of our app. Question Has anyone successfully implemented a similar setup? Specifically: • Capturing 48MP photos with the ultra-wide camera while ARKit is actively using the main camera. • Avoiding conflicts between ARKit and AVCaptureSession for the ultra-wide camera. Any insights, suggestions, or alternative approaches would be greatly appreciated. Thank you in advance for your help! 😊

I was able to obtain the depth map image using AVCapturePhotoOutput from the delegate method func photoOutput(_ output: AVCapturePhotoOutput, didFinishProcessingPhoto photo: AVCapturePhoto, error: (any Error)?) I convert the depth map to kCVPixelFormatType_DepthFloat32 format and get the pixel values of the depth map using the below code func convertDepthData(depthMap: CVPixelBuffer) -> [[Float32]] { let width = CVPixelBufferGetWidth(depthMap) let height = CVPixelBufferGetHeight(depthMap) var convertedDepthMap: [[Float32]] = Array( repeating: Array(repeating: 0, count: width), count: height ) CVPixelBufferLockBaseAddress(depthMap, CVPixelBufferLockFlags(rawValue: 2)) let floatBuffer = unsafeBitCast( CVPixelBufferGetBaseAddress(depthMap), to: UnsafeMutablePointer<Float32>.self ) for row in 0 ..< height { for col in 0 ..< width { if floatBuffer[width * row + col].isFinite{ convertedDepthMap[row][col] = floatBuffer[width * row + col] } } } CVPixelBufferUnlockBaseAddress(depthMap, CVPixelBufferLockFlags(rawValue: 2)) return convertedDepthMap } Is this the right way of accessing the depth float values from a depth map. And what will be the unit for it. Because some times the depth values are in range of 0.7 when I keep the device close to the subject around 15 to 30 cm.

I'm trying to capture the depth map image using true depth camera in iPhone 15 plus. I was able to setup the AVCapture session with AVCaptureDeviceInput as builtInTrueDepthCamera and AVCapturePhotoOutput with isDepthDataDeliveryEnabled set as true. I also manually made the activeDepthDataFormat of AVCapture device to kCVPixelFormatType_DepthFloat16 or kCVPixelFormatType_DepthFloat32. Finally I have enabled isDepthDataDeliveryEnabled, embedsDepthDataInPhoto , embedsPortraitEffectsMatteInPhoto and embedsSemanticSegmentationMattesInPhoto in AVCapturePhotoSettings before capturing the photo using capturePhoto(with: photoSettings, delegate: self) method. I have checked manually printing the activeDepthDataFormat of AVCapture device. First before setting it by default it is Optional('dpth'/'hdis' 640x 480, { 2- 30 fps}, photo dims:{}, fov:73.699, system exposure bias range:-2.0-2.0) After forcing it to kCVPixelFormatType_DepthFloat16 or kCVPixelFormatType_DepthFloat32 the format is Optional('dpth'/'hdep' 160x 120, { 2- 30 fps}, photo dims:{}, fov:73.699, system exposure bias range:-2.0-2.0) But when I receive the captured photo in func photoOutput(_ output: AVCapturePhotoOutput, didFinishProcessingPhoto photo: AVCapturePhoto, error: (any Error)?) The depth map is Optional(hdis 640x480 (high/abs) calibration:{intrinsicMatrix: [2723.07 0.00 2016.00 | 0.00 2723.07 1512.00 | 0.00 0.00 1.00], extrinsicMatrix: [1.00 0.00 0.00 0.00 | 0.00 1.00 0.00 0.00 | 0.00 0.00 1.00 0.00] pixelSize:0.001 mm, distortionCenter:{2016.00,1512.00}, ref:{4032x3024}}) Here it shows hdis instead of hdep, why is it capturing disparity map instead of true depth map. The depth quality is high and depth data accuracy is absolute. Here is my code import UIKit import AVKit import AVFoundation class ViewController: UIViewController, AVCapturePhotoCaptureDelegate { @IBOutlet weak var previewView: UIView! @IBOutlet weak var resultLbl: UILabel! private var session = AVCaptureSession() private var captureDevice: AVCaptureDevice? private var inputDevice: AVCaptureDeviceInput? private var photoOutput: AVCapturePhotoOutput? private var photoSettings: AVCapturePhotoSettings? private var cameraPreviewLayer: AVCaptureVideoPreviewLayer? override func viewDidLoad() { super.viewDidLoad() // Do any additional setup after loading the view. self.setupCaptureSession() } func setupCaptureSession(){ captureDevice = AVCaptureDevice.default(.builtInTrueDepthCamera, for: .video, position: .unspecified) guard let captureDevice else{ print("ERROR::UNABLE TO SET TRUE DEPTH CAMERA ") return } session.beginConfiguration() do{ inputDevice = try AVCaptureDeviceInput(device: captureDevice) guard let inputDevice else{ print("ERROR: UNABLE TO SET UP INPUT DEVICE") return } if session.canAddInput(inputDevice){ session.addInput(inputDevice) } } catch{ print(error) } photoOutput = AVCapturePhotoOutput() guard let photoOutput else{ print("ERROR: UNABLE TO SET UP PHOTO OUTPUT") return } if session.canAddOutput(photoOutput){ session.addOutput(photoOutput) } session.sessionPreset = .photo photoOutput.isDepthDataDeliveryEnabled = photoOutput.isDepthDataDeliverySupported print("IS DEPTH ENABLED:: \(photoOutput.isDepthDataDeliveryEnabled)") session.commitConfiguration() let availableFormats = captureDevice.activeFormat.supportedDepthDataFormats let depthFormat = availableFormats.filter { format in let pixelFormatType = CMFormatDescriptionGetMediaSubType(format.formatDescription) return (pixelFormatType == kCVPixelFormatType_DepthFloat16 || pixelFormatType == kCVPixelFormatType_DepthFloat32) }.first session.beginConfiguration() try! captureDevice.lockForConfiguration() captureDevice.activeDepthDataFormat = depthFormat captureDevice.unlockForConfiguration() session.commitConfiguration() self.setupPreviewLayer() } func setupPreviewLayer(){ cameraPreviewLayer = AVCaptureVideoPreviewLayer(session: session) cameraPreviewLayer?.videoGravity = .resizeAspectFill if let cameraPreviewLayer{ self.previewView.layer.addSublayer(cameraPreviewLayer) cameraPreviewLayer.frame = self.previewView.bounds } DispatchQueue.global(qos: .userInteractive).async { self.session.startRunning() } } @IBAction func captureBtnPressed(_ sender: Any) { photoSettings = AVCapturePhotoSettings(format: [AVVideoCodecKey:AVVideoCodecType.jpeg]) guard let photoSettings else{ print("ERROR: UNABLE TO SETUP PHOTO SETTINGS") return } guard let photoOutput else{ print("ERROR: UNABLE TO SET UP PHOTO OUTPUT") return } photoSettings.isDepthDataDeliveryEnabled = photoOutput.isDepthDataDeliverySupported photoSettings.embedsDepthDataInPhoto = true photoSettings.embedsPortraitEffectsMatteInPhoto = true photoSettings.embedsSemanticSegmentationMattesInPhoto = true photoOutput.capturePhoto(with: photoSettings, delegate: self) } func photoOutput(_ output: AVCapturePhotoOutput, didFinishProcessingPhoto photo: AVCapturePhoto, error: (any Error)?) { print(photo.depthData) switch photo.depthData?.depthDataQuality { case .low: print("Depth quality is low") case .high: print("Depth quality is high") case nil: print("Depth quality is nil") } switch photo.depthData?.depthDataAccuracy { case .relative: print("Depth accuarcy is relative") case .absolute: print("Depth accuarcy is absolute") case nil: print("Depth accuarcy is nil") } if let imageData = photo.fileDataRepresentation(){ if let image = UIImage(data: imageData){ UIImageWriteToSavedPhotosAlbum(image, nil, nil, nil) } } } }

When trying to edit some Live Photos, calling PHLivePhotoEditingContext.saveLivePhoto results in the following error: Error Domain=AVFoundationErrorDomain Code=-11800 "The operation could not be completed" UserInfo={NSLocalizedFailureReason=An unknown error occurred (-12815), NSLocalizedDescription=The operation could not be completed, NSUnderlyingError=0x300d05380 {Error Domain=NSOSStatusErrorDomain Code=-12815 "(null)"}} I was able to replicate it on my device by taking a new Live Photo. Not sure what's wrong with that one specifically, not all Live Photos replicate the issue. I've submitted FB15880825 with a sysdiagnose and a Photos Diagnostics as well. Any ideas what's going on here? It's impacting multiple customers. Thanks!

Our app involves using the camera to scan barcodes or QR codes, with a working distance of about 5 cm. However, we’ve noticed variations in the focus distance of camera lenses across different iPhone models. Currently, we mainly use two types of lenses: wide-angle and ultra-wide-angle. • For iPhone 13 and earlier models, we use the wide-angle lens. • For iPhone 13 Pro and later models, we use the ultra-wide-angle lens. We are not certain if this setup is correct since we don’t have all iPhone models to test.
There is a users have reported focus issues on his iPhone 15. We would like to ask if there’s a resource where we can find the minimum focus distance of different cameras in each iPhone model. This is to verify whether our current configuration is accurate. Alternatively, if such data is not readily available, could apple tam advise which camera should be used on various iPhone models for scenarios with a working distance of approximately 5 cm? Thank you!

I'm trying to implement anti-spoofing in iOS app using iphone true depth front camera. I have checked the following questions still can't find a proper working solution. I trained a coreML model using 22000 depth human face images and 22000 non-human face(objects,food etc) images. The accuracy of the model is very less. When testing out with flat 2d images shown on a smartphone screen I found that I get depth map even for flat 2D images like this. Even though the image is flat how does it give the depth map for the person shown in the flat 2D picture so the model thinks that it is a real face instead of a spoofed one. I implemented depth capture by following this documentation and I made sure that I get depth map instead of disparity map https://developer.apple.com/documentation/avfoundation/additional_data_capture/capturing_photos_with_depth My next approach was to use NCNN framework to implement anti-spoofing by using the model used in the Mini-vision android anti-spoofing sample. I rewrote their library in iOS by using the objective C++ wrapper for C++ as the sample was only available for android app. And I tested by feeding 80x80 UI-Image in a open cv matrix format it's accurracy is less than the android one. How can I solve this problem.

I'm building a custom camera screen that displays the camera image on a preview layer and then captures an image, using AVCaptureSession. When the picture is captured, I immediately load it into a UIImageView in order to display it to the user for approval. I've actually done this many times before, but this is the first time I've tried to do it in an app that supports interface rotation. If I hold the phone in Portrait mode and capture a picture, everything works as expected. When the user rotates the phone into Landscape orientation, I detect this and I replace the preview layer (AVCaptureVideoPreviewLayer) with a new one, specifying connection.videoRotationAngle in order to make the image appear in the right orientation. I'm a little surprised that this is necessary, and it's not a smooth transition, but that doesn't matter. What does matter is that when I capture the image, it is in the wrong orientation. I tried rotating it myself, but this doesn't seem to make any difference. What am I doing wrong?

Within my app, I have: for try await update in LockedCameraCaptureManager.shared.sessionContentUpdates { It seems that the first time my app opens from LockedCameraCapture (after enabling camera permissions etc...) this update is never called and the user will not see their capture (.added or .initial) If I then try to take another picture/video through my LockedCameraCapture control, it takes the video, opens the app as before, but this time sessionContentUpdates is called twice, once for the first video and once for the second video! After that it doesn't seem to occur again and all works perfectly! My device is: iPhone 16 Pro Max, iOS 18.2 developer beta Has anyone experienced this?

I have an app that allows the user to change a photo’s EXIF metadata. To do this, I request a content editing input, get the full size image, modify its properties, create a content editing output, write the output image to the rendered content URL, then call performChanges on the PHPhotoLibrary creating an asset change request for that asset setting its content editing output. This works as expected for regular photos but Live Photos get turned off converted to a regular photo. To address this, I’m doing something similar by changing the properties of the .photo image in the Live Photo. I detect when the content editing input has a Live Photo, create a Live Photo editing context, set a frame processor that returns the frame’s image after setting its properties to the updated properties when the frame type is photo, then I create the content editing output and save the Live Photo to that output. It modifies the Live Photo successfully, but the metadata is not updated. If you get the full size image again the properties are the original properties. If you look at the EXIF metadata using an app like Metapho it remains unchanged. What am I doing wrong here? Thanks! let imageURL = contentEditingInput.fullSizeImageURL! let inputImage = CIImage(contentsOf: imageURL, options: [.applyOrientationProperty: true])! var metadata: [AnyHashable: Any] = inputImage.properties // Edit the metadata as desired... let editingContext = PHLivePhotoEditingContext(livePhotoEditingInput: contentEditingInput)! editingContext.frameProcessor = { frame, error -> CIImage? in // Edit only the still photo if frame.type == .photo { return frame.image.settingProperties(metadata) } return frame.image } let contentEditingOutput = try await withCheckedThrowingContinuation { continuation in let editingOutput = PHContentEditingOutput(contentEditingInput: contentEditingInput) editingOutput.adjustmentData = adjustmentData editingContext.saveLivePhoto(to: editingOutput) { success, error in if success { continuation.resume(returning: editingOutput) } else { continuation.resume(throwing: error!) } } } try await PHPhotoLibrary.shared().performChanges { let request = PHAssetChangeRequest(for: asset) request.contentEditingOutput = contentEditingOutput }

Hi All, I'm working on a camera system extension where the main app is supposed to transfer a video stream using IOSurface memory sharing to the cam extension. I have built a sample app that does contains all the logic, but without a camera extension. So I'm essentially using IOSurface to render a video in one SwiftUI view and show the result in another SwiftUI view. Just for testing purposes. And everything works fine so far. Now, when moving the receiver code to the camera extensions, I'm having problems in accessing the IOSurface via ID. I am sharing the IOSurface ID via UserDefaults. I know from the logs the ID is correctly transferred. Here is the code that uses IOSurfaceLookup to get the IOSurface. But this fails with the given message. The error message prints the surface ID which is the correct one. I know this from the main app where I get the ID and print it as well. private var surfaceId: Int = -1 { didSet { logger.info("surfaceId has changed") if surfaceId == -1 { stopReceivingFrames() ioSurface = nil } else { guard let surface = IOSurfaceLookup(IOSurfaceID(surfaceId)) else { logger.error("failed to lookup IOSurface with ID: \(self.surfaceId)") return } self.ioSurface = surface logger.info("surface set, now starting receiving frames") startReceivingFrames() } } } My gut feeling says that this issue might be related to some missing entitlement, sandboxing. In general, I have a working camera extension. I'm just not able to render a video in the main app, and send it over to the camera extension to overlay another web cam. Both, the main app and camera extension are in the same XCode workspace and share the same AppGroup. In short, my actual questions are: Is there any entitlement required for using IOSurface between app and camera system extension? Is using IOSurface actually possible in system extensions? Is there any specific setting/requirement that I need to handle to make this work?

We are experiencing thousands of crashes in our application when attempting to present the camera through a Web View. The app crashes during this process, and the crash logs point to WebCore::AVVideoCaptureSource::create WebCore::RealtimeMediaSourceCenter::getUserMediaDevices. This issue has only been observed in iOS 18.2 beta versions (beta 1 - 22C5109p, beta 2 - 22C5125e, beta 3 - 22C5131e). In iOS versions below 18.2, the functionality works and we haven't identified any correlation with specific device models. The problem seems to stem from a WebCore framework introduced in these beta releases 18.2. We kindly request a review and fix for this issue in upcoming beta releases to restore functionality. Let us know if there are any workarounds or adjustments we can implement in the interim. Thank you for your attention to this matter.

Hi. I encounter some random crashes of my camera app. After some investigations, I found that it's terminated by the system and the crash log did be generated but the information is not quite useful, and here is the log found via the Console app. Termination & Crash log "Camera not actively used; AVCaptureEventInteraction not installed": Received termination request from [osservice<com.apple.SpringBoard>:10931] on <RBSProcessPredicate <RBSProcessInstancePredicate| [app<com.juniperphoton.PhotonCam]>> with context <RBSTerminateContext| explanation:Capture Application Requirements Unmet: "Camera not actively used; AVCaptureEventInteraction not installed" reportType:CrashLog maxTerminationResistance:Interactive> The crash log exported from the device will have some common information like: It's a EXC_CRASH (SIGKILL) type with no termination reason.

Also, when it comes to the memory consumption, there is no JetsamEvent around the crash time. Device and app information Additionally, some information about the tech stack and the current state of my device and my app: iPhone 16 Pro with iOS 18.2 Beta 3. The app is a camera based app(it's PhotonCam and you can find it on the App Store), its main functionality is the camera feature using AVFoundation + Core Image + Metal to deliver camera functionality. It has adopted the Camera Control, AVCaptureEventInteraction and LockedCameraCapture features. If I remember it right, it occurs in iOS 18.1 Release build, but currently I have no such device to confirm. But in iOS 17.x the issue has never happened. Regarding to this termination, on top of my head is the "watchdog" mechanism that will terminate the process that is running on the LockedCameraCapture feature. However I can make sure that currently the app is running as the main target on the home screen. Has anybody encountered this kind of issue and has found some solutions? Thanks in advance.

Hi fellow iOS developers! 👋 I've written a Swift code that converts a video (from a URL) into a Live Photo after downloading it. The conversion process seems fine, but when I try to set the generated Live Photo as a wallpaper on iOS 17+, it shows the message 'Motion not Available.' Has anyone else experienced this issue or know why this might be happening? Could it be related to changes in iOS 17 Live Photo handling or the generated file structure? Any help or suggestions would be greatly appreciated! 🙏
