In the image control state storage method according to the present invention made as described above, when the user of the image processing apparatus drives the keys of the key metrics K or the remote controller 10, the microcomputer MC performs a key driving determination step S1 to perform this operation. It becomes aware.

Then, the microcomputer MC performs the selection key driving discrimination step S2 to determine whether the driven key is the selection key, and when the selection key is not driven, the other function keys are executed by performing the function key discrimination step S3. It is determined whether it is driven.

At this time, if the other function key is driven, the microcomputer MC performs the other function performing step S4 for the image processing apparatus to perform the other key function according to the other function key.

When the selection key driving determination step S2 is driven, the microcomputer MC applies a control signal to the door bar generating unit OSD, and the monitor or the like displays the screen adjustment selection mode as shown in FIG. To be displayed.

At this time, the microcomputer MC applies a control signal to the character generating unit OSD so that the color of the portion displaying the mode of the selected selection key and the portion displaying the other mode is different from each other (S5). Do this.

Accordingly, the user visually confirms whether the mode of the video signal to be adjusted is correct and then adjusts the video signal to a desired state by driving the image control key.

At this time, the microcomputer MC performs an image control key driving determination step S6 to recognize that the image control key is driven, and outputs a control signal according to the operation of the sound image control key to the character generator OSD and the image processor. An image adjustment step S7 to be applied to 30 is performed.

That is, the microcomputer MC selects a mode of image control to be adjusted according to the driving of the selection key, and outputs a control signal for controlling the image of the selected image control mode by driving the image control key. And the image processor 30.

As a specific example, when the user wants to adjust the contrast of the image, the contrast selection key is driven. Accordingly, the mode state as shown in FIG. 3 is displayed on the monitor, and the color of the portion displaying the contrast is different from the other portions.

At this time, if the contrast is to be strongly adjusted, the control key outputs a signal in a strong direction using the control key.

Therefore, when the user wants to watch the video signal adjusted according to the preferences or the surrounding environment, when the corresponding key of the storage unit is driven, the image processing unit 30 processes the video signal according to the information stored in the storage unit.

Then, the microcomputer MC performs the key driving determination step S13 to determine whether the key of the key metrics K is driven, and when the key is not driven, the predetermined time passes by performing the time-lapse determination step S14. In response to the control signal being applied to the character generating unit OSD, the character generating unit OSD stops outputting the character signal, and performs the display erasing step S18 for stopping displaying the mode displayed on the monitor.

If the storage key is not driven by performing the storage key driving determination steps S9, S10, and S11, the microcomputer MC performs a time-lapse determination step S15 to determine whether a predetermined time has elapsed.

After the elapsed time elapses, the microcomputer MC applies a control signal to the character generating unit OSD, so that the character generating unit OSD outputs a character signal displaying a character of "temporary".

Then, the microcomputer MC performs the time elapsed determination step S17 so that the character "temporary" is displayed continuously, and when the predetermined time elapses, the display erasing step S18 is performed to output the character signal to the character display unit OSD. By stopping the display, only the video signal is displayed on the monitor.

That is, according to the present invention, a plurality of storage keys are configured in the key metallic, and a plurality of storage units corresponding to the storage keys are stored in the microcomputer to store a plurality of control states of the video signals in the storage.
