Embodiment Construction

[0045] Fig. 2 is a block diagram of the best correlation matching system for judging trajectory behavior of the present invention, which is to find the first image from the 0th image, the first image and the second image in the video data stream The corresponding motion vector of a block in the second image (i is an integer), each image is composed of a plurality of blocks in rows and columns, and each block includes rows and columns A plurality of pixels, the system includes a light source 210 , a pixel array device 220 (pixel array), an analog-to-digital conversion device 230 and a control device 240 .

[0046] The light source 210 is used to illuminate a sampling plane, which is preferably a light emitting diode. The pixel array device 220 is composed of a plurality of photosensitive elements to capture the sampling plane to form the video data stream. The analog to digital converter 230 (Analogue to digital converter, ADC) is coupled to the pixel array device 220 to conve...

Abstract

This invention relates to an optimum match method and a system used in judging tracing behaviors, which searches for the related moving vector of a block of the first image in the second image in the first and second images, in which, each image is composed of multiple blocks in line and column, every block contains multiple pixels in line and column. The method divides the search view window zone position of the second image into multiple sets of sub-search view windows and selects one from them as an executing one then places the central points of a block on-all positions in said executing search view window to carry out matched operation of pixels of a block with pixels of the second image to reduce time of the matched operation.

Description

technical field [0001] The present invention relates to a best correlation matching method and system for judging trajectory behavior, in particular to a best correlation matching method and system for judging trajectory behavior on an optical mouse. Background technique [0002] The known optical mouse has an image sensing device, which is composed of a plurality of image sensing elements, and uses the front and rear images sensed by the image sensing device to detect movement. The known method of detecting the amount of movement using an optical mouse uses a partial image of the first image as a search block (search block), and performs correlation (correlation) between the search block and the second image at different positions. calculate. Afterwards, find out the absolute minimum value as the displacement according to the calculated correlation. [0003] FIG. 1 shows an example of an image when performing the displacement detection method of an optical mouse. As show...
