Abstract:
A moving quantity detection apparatus, comprising:image input means for inputting a plurality of images in time series at predetermined intervals; full size image processing means for dividing one image into a plurality of blocks of a predetermined size, and for calculating evaluation values between a particular block on the one image and each neighboring block corresponding to the particular block in time series images; reduced image processing means for reducing the plurality of images by a predetermined reduction ratio, for dividing one reduced image corresponding to the one image into a plurality of blocks of the predetermined size, and for calculating evaluation values between a particular block on the one reduced image and each neighboring block corresponding to the particular block on other reduced images, wherein at least one predetermined interval is proportional to the predetermined reduction ratio; and moving quantity detection means for selecting the neighboring block having the highest evaluation value, and for calculating a relative distance between the particular block on the one image and the one neighboring block on the time serial image.
