Paper Abstract

We have developed an image processing algorithm that reduces lateral chromatic aberration. It has been implemented in Nikon digital single-lens-reflex cameras and application software. We have developed the aberration detection method which analyzes capture images and detect the aberrations of the image without lens information. Moreover, we have developed the aberration correction method optimized for raw images, which are mosaic images with Bayer color filter array. We also have developed the correction method optimized for in-camera processed images, whose color shift structures are distorted by in-camera processing.
