Hello,

I am developing a camera app which need to set following features for Pixel 5a phone.

1. Night Sight mode

2. Zoom

3. Exposure

4. Shadows

I am facing following challenges.

1. I have implemented night sight mode using camera extension api. But I am facing problem with accessing vendor extension. Does Pixel 5a support CameraX vendor extension? If not, then how can I set night sight mode for Pixel 5a?

2. Can I set exposure and shadows using CameraX api?

Thanks

Hi,

Thanks for raising the questions.

1. CameraX vendor extension is not enabled on Pixel 5a yet (not enabled on all Pixel series devices yet). After it is enabled in the future, 3P apps can access the extension effects via CameraX (camera-extensions) or CameraExtensionCharacteristics. Except for these two approaches, there should be no other approach to access Pixel series devices' special effects.
2. Please try CameraControl#setExposureCompensationIndex(int) to adjust the exposure setting which is supported by Camera2 standard API. About the brightness/shadows adjustment feature of Google Camera App, it is its private feature and different from the Camera2 standard exposure adjustment. There should be no public API to access it.

Thank you Chen for the clarification.
Is there any way to install extension manually and then access Pixel series devices' special effects?

Thanks
Mohammad

Unfortunately, it can't be supported by installing manually. The OEMs' vendor extension implementations might need to add some private HAL or system level implementation. It generally needs an OTA to update the full ROM to support extension.

" Camera2 provides an API for accessing effects—bokeh, HDR, and others—that have been implemented by phone manufacturers for specific phones." What are the Camera2 extensions API supported devices? Is the list the same as the CameraX supported device list? Thanks Mohammad

Hi Mohammad,

What are the Camera2 extensions API supported devices? Is the list the same as the CameraX supported device list?

Yes for both questions, however Camera2 requires Android 12 as well as support for the same CameraX Extensions. Additionally you can check if a device supports this (Camera2 Extensions) with a device property: ro.camerax.extensions.enabled

Thanks

Hello,
I have bought one listed extension supported device Motorola g7 play. But still I am finding extensions not available, I cannot enable extensions for this device.

if (hdrImageCaptureExtender.isExtensionAvailable(cameraSelector)) {
    // Enable the extension if available.
    hdrImageCaptureExtender.enableExtension(cameraSelector);
}

Any suggestions?

Thanks
Mohammad

Hi Mohammad,

Are you seeing an error or anything you can share why this is not behaving as expected?

From the log analysis I only found "ExtenderVersion: No versioning extender found. Falling back to default".

Thanks
