MOTION VECTOR DETECTOR AND CONTROL METHOD THEREOF

Title:

MOTION VECTOR DETECTOR AND CONTROL METHOD THEREOF

Document Type and Number:

Japanese Patent JP2018032949

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To provide a motion vector detector which can realize efficient reading of a reference area, and suppression of decrease in detection accuracy of motion vector, without increasing the capacity of internal memory even when resolution of image increased, and to provide a control method thereof.SOLUTION: When it is judged that the horizontal resolution of an object image detecting a motion vector is not less than a threshold, motion vector is detected in predetermined order for the blocks included in a region, with the object image as one region. When it is judged that the horizontal resolution of the object image is not less than the threshold, processing order of the objective block is changed to detect motion vector in the predetermined order for the blocks included in the region, for each multiple regions dividing the object image in the horizontal direction.SELECTED DRAWING: Figure 1
