如何更改android中的whiteBalance增益值?
我想获取当前增益的值并更改 RGB 增益的值。
在 iOS 中,Apple提供了 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;
}
我们如何使用cameraX在android中实现这一点?
COLOR_CORRECTION_GAINS
COLOR_CORRECTION_MODE
我已经检查了有关通道控制的文档。但是我们如何使用新控件更改色彩校正并重置 cameraX 预览?
