    摘要： An image processing apparatus and method are provided. The image processing apparatus includes a blur kernel estimator and an image restorer. The blur kernel estimator is configured to estimate a blur kernel of a first image using the first image and a second image, wherein the first image includes multi-channel color image data and the second image includes single-channel image data and is obtained with a shorter exposure time than the first image. The image restorer is configured to generate a blurred image of the second image using the blur kernel, and restore an image using residual images between images for respective channels of the first image and the blurred image of the second image, the second image, and the blur kernel.
