  • Patent number: 5164824
    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.
