MOTION BLUR DEVICE, METHOD AND PROGRAM

A motion blur control device uses inter-frame movement computation means to compute an inter-frame movement direction and an inter-frame movement amount from plural frame images acquired at a specific time interval. Motion blur correction means then generates a corrected frame image by correcting motion blur in a specific frame image in plural frame images based on the blur amount set within a range not exceeding the inter-frame movement amount and based on the inter-frame movement direction. Evaluation means evaluates the corrected frame image using a motion blur evaluation function. The motion blur control device controls the blur amount such that the motion blur evaluation function satisfies a specific condition.
