Patent ID: 7885475

Claim:
A motion adaptive image processing apparatus to selectively apply a motion adaptive image processing procedure to a sequence of images, the apparatus comprising: an image processor comprising: an image divider unit to divide current images, previous images and next images in a sequence of images into at least one current region of a predetermined size, at least one corresponding previous region, and at least one corresponding next region, respectively; a region analysis unit to receive each current region and corresponding previous region and next region from the image divider unit, to determine a motion class of the current region by comparing the current region with at least one of the previous region and the next region, to provide a range of a threshold according to the determined motion class, and to calculate a dispersion value of pixels in the current region; and a weight calculating unit to calculate a motion change of the current image based on differences between corresponding pixel values of the previous image and the next image, to determine the threshold based on the provided range and the calculated dispersion value, and to determine a weight corresponding to a pixel from the current region to be applied to the motion adaptive image processing procedure based on the determined threshold and the calculated motion change.
