摘要:
A frame extraction unit detects a luminance change point frame in which the brightness change amount between frames is equal to or higher than a threshold value from a moving image formed by a plurality of frames. A flash check unit checks the presence/absence of a flash portion in the moving image on the basis of the detected luminance change point frame.
