IMAGE PROCESSING APPARATUS AND METHOD
First Claim
1. An image processing apparatus, comprising:
- a blur kernel estimator configured to estimate a blur kernel of a first image using the first image and a second image, whereinthe first image comprises multi-channel color image data, andthe second image comprises single-channel image data and is obtained with a shorter exposure time than the first image; and
an image restorer 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.

Abstract
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.

14. An image processing method performed by an image processing apparatus, the method comprising:
-
obtaining a first image having multi-channel color image data, and a second image having single-channel image data obtained with a shorter exposure time than the first image; estimating a blur kernel of the first image using the first image and the second image; generating a blurred image of the second image using the blur kernel; generating residual images for respective channels of the first image between images for the respective channels and the blurred image of the second image; and restoring an image using the second image, the residual images, and the blur kernel. - View Dependent Claims (15, 16, 17, 18, 19, 20)

21. A computer-readable storage medium storing a program to process an image, comprising instructions to cause a computer to:
-
obtain a first image having multi-channel color image data, and a second image having single-channel image data obtained with a shorter exposure time than the first image; estimate a blur kernel of the first image using the first image and the second image; generate a blurred image of the second image using the blur kernel; generate residual images for respective channels of the first image between images for the respective channels and the blurred image of the second image; and restore an image using the second image, the residual images, and the blur kernel. - View Dependent Claims (22)
