Abstract
A movement amount detected by a movement detection circuit on the basis of an image signal corresponding to an object image is input to a minimum value detection circuit. This detection circuit sets an operation time for the detection of the minimum value by using fuzzy inference on the basis of the movement amount and the gradient amount of the movement. An image signal corresponding to the smallest movement amount in this operation time is retained in a freeze memory. In this case, the operation time is set by fuzzy inference by using the movement amount and the gradient amount as factors for fuzzy inference so that the operation time can be set automatically to a time suitable for obtaining static images possessing a small amount of movement.
