METHOD OF DETECTING MOVING OBJECT AND MOVING OBJECT DETECTING DEVICE

摘要

The present invention detects a moving object using a normalized feature amount unsusceptible to a change in the brightness of a display screen. The normalized feature amount is obtained by dividing an image into block units, calculating the feature amount for each block and normalizing the feature amount with the average of the brightness and so forth. By comparing the normalized feature amount of the blocks of an input image with the normalized feature amount calculated from the same position in the background, a moving object can be detected without being affected by a change in the brightness of a display screen.
