PROBLEM TO BE SOLVED: To provide an object detection device which can reduce a calculation amount by focusing on the ratio of dynamic state pixels to static state pixels in a cell and eliminating a vector operation. ! SOLUTION: An object detection device comprises: an image input part 1 which generates an image frame group; a temporal change extraction part 2 which calculates the dispersion value of luminance from luminance change information on the same portion for each pixel of a reference pixel and an image frame preceding by a predetermined number or after the predetermined number from the reference frame to determine that the pixel with the dispersion value of the luminance larger than a prescribed dispersion value is in the dynamic state and pixels in other states are in the static state; an inter-frame feature extraction part 3 which forms a cell consisting of a plurality of adjacent pixels in the reference frame, calculating the ratio of the dynamic state pixels to the static state pixels for each |
