I would like to get the value of the current gains and change the value of the RGB gains.
In iOS, Apple provides setWhiteBalanceModeLockedWithDeviceWhiteBalanceGains:completionHandler
.
- (void)setWhiteBalanceGains:(AVCaptureWhiteBalanceGains)gains
{
NSError *error = nil;
if ( [self.captureDevice lockForConfiguration:&error] ) {
AVCaptureWhiteBalanceGains normalizedGains = [self normalizedGains:gains];
[self.captureDevice setWhiteBalanceModeLockedWithDeviceWhiteBalanceGains:normalizedGains completionHandler:nil];
[self.captureDevice unlockForConfiguration];
}
else {
NSLog( @"Could not lock device for configuration: %@", error );
}
}
- (AVCaptureWhiteBalanceGains)normalizedGains:(AVCaptureWhiteBalanceGains) g
{
AVCaptureWhiteBalanceGains gains = g;
gains.redGain = MAX(gains.redGain, 1.0f);
gains.greenGain = MAX(gains.greenGain, 3.0f);
gains.blueGain = MAX(gains.blueGain, 18.0f);
return gains;
}
How can we achieve this in android using cameraX?
COLOR_CORRECTION_GAINS
COLOR_CORRECTION_MODE
I have checked in the doc regarding channel control. But how can we change color correction and reset the cameraX preview with the new control?
from How can I change the whiteBalance gains value in android?
