The adjusted data, for example, brightness: +5, contrast: -1, color density: +1, hue: 0, sharpness: +10, etc., are given a set level value ID and stored in the memory 323 (S312). .

Here, when the set level value is stored, a password is provided for each set level value ID and stored (S31).
3) By doing so, it is possible to prevent a registrant from inadvertently changing or deleting a set value even if another person or the person himself / herself does not intend.

By the above processing, the set level value of each item can be registered.

Next, a description will be given of a process when the set level value is changed by another person or when the set level value is returned to the previously set level value.

A set level value ID is selected from the main body operation section 80 or the system controller 2 (S314).
When the set level value ID is selected, the control unit 324 calls up each item of the adjustment information and the set level value stored in the memory 323 (S315). The control unit 324 transmits the adjustment information called from the memory 323 to the video signal processing unit 20.
