MOVING BODY DETECTOR, MOVING BODY DETECTION SYSTEM AND MOVING BODY DETECTION METHOD

摘要

PROBLEM TO BE SOLVED: To detect a moving body at a low cost. SOLUTION: An MPEG encoder 11 uses in-frame (or in-field) coding to compress moving picture data, a data quantity detection means 13 detects a quantity of moving picture data compressed by the MPEG encoder 11, a decision means 14 extracts the data quantity for inter-frame (or inter-field) coding among the data quantity detected by the data quantity detection means 13 and decides whether or not a moving body exists in the moving picture on the basis of the extracted data quantity at the inter-frame (or inter-field) coding.
