Abstract

A television set carries out communications with a remote control. When the television set displays a picture based on a picture signal subjected to quality adjustment, a signal level of a quality adjustment parameter is obtained, and the data indicating the obtained signal level is transmitted to the remote control. The remote control displays the received data. The user checks the displayed data, and enters data for changing the signal level so that the remote control transmits the entered data to the television set. The television set receives the changed level data, and adjusts the quality relating to the picture signal based on the received level data. The television set displays the picture of the quality adjusted according to the signal level changed by the user.

Claims

1. A television set comprising a picture quality processing device adjusting a quality of a displayed picture, wherein

said picture quality adjusting device includes a picture output unit and a remote control unit to be operated for remote controlling of said picture output unit,

said picture output unit includes:

picture processing means for performing picture signal processing including quality adjustment based on a provided signal of a quality adjustment parameter,

display means for displaying a picture based on a picture signal processed by said picture processing means,

adjustment level obtaining means for obtaining a signal level of said quality adjustment parameter for said quality adjustment,

output-side transmitting means for transmitting level data indicating the signal level of said quality adjustment parameter obtained from said adjustment level obtaining means to said remote control unit, and

adjustment signal supply means for providing a signal of said quality adjustment parameter at the signal level indicated by said level data received from said remote control unit to said picture processing means;

said remote control unit includes;

operation-side display means,

level data display means for receiving said level data transmitted from said output-side transmitting means and displaying said level data on said operation-side display means,

level data input means for inputting said level data according to an external operation, and

operation-side transmitting means for transmitting said level data provided from said level data input means to said picture output unit;

said level data is data indicating a relative level of said signal of said quality adjusting parameter;

said output-side transmitting means has means for converting the signal level of said obtained quality adjusting parameter to said level data indicating said relative level;

said adjustment signal supply means has means for converting said received level data to the signal level of said quality adjustment parameter indicated by said level data;

said picture output unit further has message transmitting means for transmitting data of a predetermined message to said remote control unit when said level data is received from said remote control unit;

said remote control unit further has message display means for receiving the data of said predetermined message transmitted from said message transmitting means, and displaying said predetermined message on said operation-side display means;

said adjustment level obtaining means has obtainment request receiving means for receiving an obtainment request for the signal level of said desired quality adjustment parameter, and obtains the signal level of said desired quality adjustment parameter received by said obtainment request receiving means; and

said remote control unit further has obtainment request transmitting means for transmitting the obtainment request for said signal level relating to said desired quality adjustment parameter designated according to an external operation.

2. A picture quality adjusting device for adjusting a quality of a displayed picture, comprising a picture output unit, and a remote control unit to be operated for remote controlling of said picture output unit, wherein

said picture output unit includes:

picture processing means for performing picture signal processing including quality adjustment based on a provided signal of a quality adjustment parameter,

display means for displaying a picture based on a picture signal processed by said picture processing means,

adjustment level obtaining means for obtaining a signal level of said quality adjustment parameter for said quality adjustment,

output-side transmitting means for transmitting level data indicating the signal level of said quality adjustment parameter obtained from said adjustment level obtaining means to said remote control unit, and

adjustment signal supply means for providing a signal of said quality adjustment parameter at the signal level indicated by said level data received from said remote control unit to said picture processing means;

said remote control unit includes; and

operation-side display means,

level data display means for receiving said level data transmitted from said output-side transmitting means and displaying received said level data on said operation-side display means,

level data input means for inputting said level data according to an external operation, and

operation-side transmitting means for transmitting said level data provided from said level data input means to said picture output unit;

3. The picture quality adjusting device according to claim 2, wherein

said level data is data indicating a relative level of said quality adjusting signal,

said output-side transmitting means has first converting means for converting the signal level of said obtained quality adjusting parameter to said level data indicating said relative level, and
