Abstract:
Systems, methods, and computer-readable media to improve multi-image color-refinement operations are disclosed for refining color differences between images in a multi-image camera system with application to disparity estimation. Recognizing that corresponding pixels between two (or more) images of a scene should have not only the same spatial location, but the same color, can be used to improve the spatial alignment of two (or more) such images and the generation of improved disparity maps. After making an initial disparity estimation and using it to align the images, colors in one image may be refined toward that of another image. (The image being color corrected may be either the reference image or the image(s) being registered with the reference image.) Repeating this process in an iterative manner allows improved spatial alignment between the images and the generation of superior disparity maps between the two (or more) images.

Claim (Index 9):
An electronic device, comprising:\n a first lens assembly; a second lens assembly; a memory operatively coupled to the first and second lens assemblies; one or more processors operatively coupled to the first and second lens assemblies and the memory, the one or more processors configured to execute instructions stored in the memory to cause the one or more processors to:\n obtain first and second input images of a scene, each input image comprising pixels, each pixel comprising a color value, wherein the first and second input images are captured at substantially the same time; \n find a disparity map between the first and second input images; \n warp the pixels of the first input image to spatially align with corresponding pixels of the second input image to generate an aligned image; \n adjust one or more pixel color values of either the first or second input image based on corresponding pixel color values of the other of the first or second input images, to generate a color-refined image; and \n repeat the finding, warping, and adjusting using the color-refined image as one of the first and second input images and the aligned image as the other of the first or second input images to obtain a color-adjusted image for output.
