Abstract

An image processing device includes an image processor that calculates a motion vector between image data of a target frame and image data of a reference frame in units of a block, and a reference frame image memory that retains image data of a past frame as the image data of the reference frame. Furthermore, the image processing device includes a primary memory that retains a matching processing range of the reference frame in calculation by the image processor, and a secondary memory that reads out and retains image data of a desired range from the image data of the reference frame stored in the reference frame image memory. The secondary memory reads out data of the matching processing range from the retained image data and supplies the read data to the primary memory.

Description

technical field [0001] The present disclosure relates to an image processing apparatus and an image processing method in which an image storage section and various image processors are connected via a system bus, and the various image processors perform respective types of image data processing by accessing the image memory. Background technique [0002] The block matching technique of obtaining the motion vector between two screens from the image information itself is an old technique. Developments have been made mainly in pan and tilt detection and object tracking of television cameras, and motion picture coding in the Moving Picture Experts Group (MPEG) system. Moreover, since the early 1990s, various technologies based on image superposition are being applied, such as sensorless camera shake correction and noise removal (noise reduction, hereinafter denoted as NR) in low-light shooting. [0003] Block matching is a method of calculating a motion vector between two scree...
