Problems solved by technology

In order to meet the requirement of processing time, it is necessary to complete the processing in units of blocks and process them one by one. At this time, since each block cannot be processed in the same way, it is not necessarily possible to weight each block in the same way only by using the edge number. get satisfactory results

Abstract

The present invention relates to a motion-vector detection device capable of detecting a motion vector between frame images accurately and promptly. The motion-vector detection device according to the present invention is a motion-vector detection device for detecting a motion vector between frame images of the preceding frame and current frame (succeeding frame), and first enhances a vertical edge of each of a plurality of image regions obtained by dividing a frame image in the vertical direction, and then obtains a vertical projection to generate projection data for one horizontal line. Next, intersections of this projection data and a first threshold value are searched, and projection data of the current frame corresponding to a motion vector detection range with each intersection placed at its center is extracted. Then, each piece of extracted projection data is added per distance from the above-mentioned each intersection, and a horizontal motion vector of the frame image is detected from the result of addition.

Description

technical field [0001] The present invention relates to a motion vector detecting device which detects a motion vector between frame images of a previous frame and a subsequent frame in a temporally contextual relationship. Background technique [0002] As a motion vector detection technique between frame images used for shake correction and the like, a representative point matching method is used to detect motion vectors from continuously captured images. In this representative point matching method, in the continuously captured images, representative points are set at the fixed positions of the images of the previous frame, and at the same time, the image of the current frame is shifted along the two-dimensional direction to carry out the correlation calculation of the representative points, thus The offset with the highest correlation is detected as the motion vector. [0003] However, in the above motion vector detection techniques, the representative points need to hav...
