Abstract: Certain aspects relate to systems and techniques for correction of color artifacts including both color aberration and color spot artifacts using a unified framework. For example, both color aberration and color spot artifacts can be corrected using a post-processing method implementing directional median filtering on chroma channels. A pixel-by-pixel correction ratio map can be built by analyzing the luma and chroma components of the image to indicate a type of color artifact associated with each pixel in the image, and a directional median filter can be selected for each pixel based on the corresponding correction ratio map value.

Abstract: Systems and methods for multi-focus imaging are disclosed. An imaging system may suggest multiple regions of interest to a user based on a preview mode of a scene of interest. The user may select a plurality of the suggested regions of interest for a multi-focus image. The imaging system calculates the autofocus parameters for each of the multiple regions of interest and captures single images of each of the regions of interest when the shutter button of the camera is pressed. The imaging system then generates a multi-focus image from the multiple images.
