A memory capable of memorizing a video signal has part of its address area into which an information signal is inhibited from being written. A writing address controller for cyclically specifying writing addresses of the memory cyclically specifies writing addresses in the remaining address area except for the part of address area to allow a plurality of different moving picture scenes to be memorized in the one and same memory.For according to a large capacity main memory, a sub-memory is interposed to access to the main memory with a predetermined information amount being as the unit, thereby facilitating address management of the main memory as well as improving a utilizing effeciency of the main memory.

This invention discloses an arrangement for suppressing an erroneous display and suppressing damage to an image display apparatus when a power source is turned on, the power source is turned off, an outlet is removed, or power fails. Particularly, this invention discloses an arrangement for stopping, for a predetermined time, input of a scanning signal or modulation signal to a display panel or application of an accelerating potential in turning on the power source. This invention discloses an arrangement for stopping input of a scanning signal or modulation signal to the display panel, and then stopping supply of power in turning off the power source.

A television camera device having an image pickup structure, with a plurality of control units, for producing an optimum image output signal that (i) corresponds to a received object image (ii) is in accordance with one of a plurality of predetermined image pickup environments. The device includes a memory for storing scene files which contain image pickup control data for the plurality of the predetermined image pickup environments, and a mode setting structure for selecting a particular scene file from the scene files stored in the memory. Further, the device includes a timer operatable in response to the selection of a scene file by the mode setting structure, and an operation structure, coupled to the image pickup structure, the memory, the mode setting structure, and the timer. The operation structure sequentially outputs to the image pickup structure intermediate image pickup control data which is between the control data of the pre-selection scene file and the control data of the post-selection scene file. The operation structure changes the intermediate control data is discrete increments at a frequency determined by the timer when the scene file is selected by the mode setting structure.
