Abstract: Methods for parameter alignment processing are described herein. An image capture device includes a first image capture device configured to capture a first image, a second image capture device configured to capture a second image, and an image signal processor connected to the first image capture device and to the second image capture device. The image signal processor is configured to apply, to the first image and the second image, at least two of a respective luminance lens shading (LLS) compensation factor, a respective color lens shading (CLS) compensation factor, a respective exposure difference compensation factor, a respective white balance compensation factor, a respective lens exposure correction (LEC) compensation factor, and a respective flare compensation factor, blend the compensated first image and the compensated second image to form a blended image, and output an image based on the blended image.

Abstract: In a method, it is determined that a detachable lens is mounted on an image capture device in a first orientation. A first image of a controlled scene is captured with the detachable lens mounted in the first orientation. It is determined that the detachable lens is mounted on the image capture device in a second orientation that is rotated approximately 180 degrees from the first orientation. A second image of the controlled scene is captured with the detachable lens in the second orientation. A first image circle center of the first image is determined. A second image circle center of the second image is determined. An average image circle center is determined, based on the first image circle center and the second image circle center. The average image circle center is provided to an image stabilization algorithm when the detachable lens is mounted on the image capture device.

Abstract: Adaptive acquisition control includes obtaining a processed image by an image capture apparatus, which includes, a target exposure component that obtains a target exposure value in accordance with target exposure input data, an aggregate gain component that obtains a target aggregate gain value and a remaining gain value in accordance with aggregate gain input data, an auto-exposure compensation component that obtains an auto-exposure compensation tone curve in accordance with auto-exposure compensation input data, a contrast control component that obtains a contrast control tone curve and a contrast control black point value, and a tone control driver that obtains a tone control tone curve and a tone control black point value, and an image signal processor that processes the current input image in accordance with the tone control tone curve and the tone control black point value to produce the processed image.

Abstract: Methods for auto white balance (AWB) processing are described herein. An image capture device includes a first image capture device to capture a first image, a second image capture device to capture a second image, and an image signal processor. The image signal processor is configured to generate a global AWB scale based on the first image and the second image, apply a first image capture device calibration factor to the global AWB scale to generate a first image capture device AWB scale, apply a second image capture device calibration factor to the global AWB scale to generate a second image capture device AWB scale, compensate the first image using the first image capture device AWB scale, compensate the second image using the second image capture device AWB scale, and output an image based on the compensated first image and compensated second image.
