PROBLEM TO BE SOLVED: To suppress breaks and fluctuations in facial detection. SOLUTION: A face detection device includes a first detection part for provisionally detecting a facial position from each frame image and a second detection part for detecting the final facial position. When the facial position of a current frame image is detected, a center view area (220) and a peripheral view area (230) around the area (220) are set with the facial position of a preceding frame image as a reference. The center view area and the peripheral view area are defined for the preceding frame image and the current frame image, and image changes between both the frame images in the center view area and the peripheral view area are detected by the calculation of motion vectors, or the like. The second detection part ultimately detects the facial position of the current frame, on the basis of detection results of the first detection part for the current frame, and the preceding frame and the image changes.
