HDR capture pipeline not resetting on X3 – subsequent normal photo appears dull after HDR capture

[ManojAtamai]

Description

While implementing HDR capture on Insta360 X3 using the iOS SDK, the camera does not appear to reset the HDR pipeline after capturing an HDR image. When capturing a normal photo immediately afterward, the resulting image appears dull / incorrectly exposed.

SDK reference:
https://github.com/Insta360Develop/iOS-SDK

Attempt 1 (As per documentation)

let options = INSTakePictureOptions()
options.mode = .aeb

INSCameraManager.shared().commandManager.takePicture(with: options) { error, info in
}

This results in the following error:

capture using takeHDRPicture method

Attempt 2

let options = INSTakePictureOptions()
options.mode = .aeb

INSCameraManager.shared().commandManager.takeHDRPicture(with: options) { error, urls, data in
}

This still did not capture HDR correctly.

Working Approach

HDR capture started working only after explicitly setting photoSubMode to HDR.

let options = INSCameraOptions()

let optionTypes: [NSNumber] = [
    NSNumber(value: INSCameraOptionsType.photoSubMode.rawValue)
]

options.photoSubMode = UInt(INSPhotoSubMode.hdr.rawValue)

INSCameraManager.shared().commandManager.setOptions(options, forTypes: optionTypes) { error, _ in
}

Issue After HDR Capture

When switching back to normal capture:

let options = INSTakePictureOptions()
options.mode = .normal

INSCameraManager.shared().commandManager.takePicture(with: options) { error, info in
}

Even after resetting:

options.photoSubMode = UInt(INSPhotoSubMode.single.rawValue)

the captured image appears dull / incorrectly exposed, suggesting the HDR pipeline is not resetting internally.

Steps to Reproduce

1. Set photoSubMode = hdr
2. Capture HDR using takeHDRPicture
3. Set photoSubMode = single
4. Capture normal photo using takePicture

Expected Behavior

Normal photos should return to standard exposure after HDR capture.

Actual Behavior

The photo appears dull / incorrectly exposed.

Device

Camera: Insta360 X3
SDK: iOS SDK from GitHub

I am attaching the captured image screenshot for the reference.

It appears to be due to underexposure. When taking regular photos, you need to adjust the exposure parameters (it's recommended to set iOS, shutter speed, and white balance to auto).

Could you please provide the iOS code?
