Abstract

A moving object detection apparatus includes a movable input section to input a plurality of images in a time series, in which a background area and a moving object are included. A calculation section divides each input image by unit of predetermined area, and calculates the moving vector between two images in a time series and a corresponding confidence value of the moving vector by unit of the predetermined area. A background area detection section detects a group of the predetermined areas, each of which moves almost equally as the background area from the input image according to the moving vector and the confidence value by unit of the predetermined area. A moving area detection section detects the area other than the background area as the moving area from the input image according to the moving vector of the background area.
