Abstract: A method and apparatus for color space conversion are provided. An apparatus for converting a color space includes at least one processor configured to convert an original full image of an original color space to a temporary image of a target color space, estimate a color space mapping parameter between the original color space and the target color space, the color space mapping parameter corresponding to the original full image, obtain a residual vector of the target color space based on the temporary image and the color space mapping parameter, convert the residual vector to a residual image of the target color space, and obtain a target full image of the target color space by combining the residual image with the temporary image.

Abstract: A method and an electronic device with image registration are provided. The method includes generating a first optical flow between a first partial image and a second partial image, which are captured by respective first and second cameras using an optical flow estimation model; generating disparity information between the first partial image and a third partial image, captured by a third camera, based on depth information of the first partial image generated using the first optical flow; and estimating a second optical flow between the first partial image and the third partial image based on the generated disparity information for generating a registration image.
