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.

Abstract: An object of the present invention is to provide an image freezing signal-processing apparatus capable of eliminating a necessity of using a large number of memories, reducing a time lag and preventing an image deviation. Sequence signals for R, G and B are stored in a first memory via an A/D converter and as well as the same are supplied to a movement detection/control circuit so that an image which displays the minimum about of movement in a predetermined time passed from the freeze signal is read from the first memory so as to be written to a still picture memory. The movement detection/control circuit stops the movement detection operation in a case where the image which displays a small amount of movement is stored in the still picture memory so as to transmit the image stored in the still picture memory as a still picture in a state in which updating is inhibited.
