Abstract

PURPOSE:To perform adjusting operation while comparing an adjustment value before the adjustment with a current adjustment value by displaying the state of the adjustment value before the operation at the same time with the adjustment value which is being adjusted and varying. CONSTITUTION:This television receiver has a timer circuit 4a which measures intervals of input of an operation key for picture quality and various adjustment memories 4b regarding the picture quality of a video signal processing part. When the operation key for picture quality adjustment is operated, for example, as a user desires, the picture quality adjustment value memory 4b of the video signal processing part 4 stores the input data and when an operation key for a picture quality adjustment value is newly operated next, the adjustment value regarding an image stored in the picture element adjustment value memory 4b and the adjustment value which is currently adjusted are outputted on a screen at the same time. Therefore, how much the adjustment value is operated, is known at a glance from the last set state and even if newly set picture quality is not desirable, the picture quality can easily be put back to the same state with the last setting, thereby maintaining the best picture quality state at all times.

FIG. 3 shows a display method when an up / down key for adjusting a picture level is operated. First, when the up / down key is input, various image quality adjustments are performed. The parameter level is displayed. That is, various adjustment values set last time and stored in the image quality adjustment value memory 4b are displayed by the level bars 21, 22, 23, 24, and 25.
And at the same time, picture level bar 2
On the right side of 3, the picture level currently being adjusted is displayed by the level bar 26. When the level bar index moves to the right side as shown in FIG. 4A and the picture level is set to DOWN, the level bar index moves to the left side as shown in FIG. 4B. By doing so, the level change is displayed.

The clock circuit 4a is provided to measure the time interval between operation key inputs for image quality adjustment. For example, even when the operation keys are input little by little, the image quality adjustment value memory 4b is provided each time. Since the value of the parameter will change and it will be difficult to compare it with the previously set parameter, the time X seconds is set in advance, and while the operation key is repeatedly input within that time X seconds, This is for preventing the value of the parameter of the image quality adjustment value memory 4b from being updated as it is regarded as one operation.
