STORAGE DEVICE, SIGNAL PROCESSOR, IMAGE SIGNAL PROCESSOR, AND THEIR METHODS

摘要

An image processor and an image processing method that can perform matching processing only with a low degree of computational complexity and accurately detect a motion vector. The image processor comprises a first feature amount extraction unit (13) that extracts a feature and the space coordinates of a pixel of interest from information on the current frame; a second feature amount extraction unit (14) that extracts from information on a reference frame a feature, a pixel of interest, the space coordinates of the pixel, the space coordinates of the neighboring area of the pixel, and distance information on the space coordinates of the pixel; a database creation unit (15) that creates a database containing the correspondence relationship among the feature, the pixel, the space coordinates of the neighboring area of the pixel, the space coordinates of the pixel, and the distance information on the space coordinates of the pixel extracted by the second feature extraction unit (14); and a motion vector detection unit (16) that obtains from the database the space coordinates of the movement destination by calculating, through a search, the distance information linked to the feature according to the feature extracted by the first feature extraction unit (15).
