Image display control method and apparatus, and display apparatus

A display apparatus comprised of a display controller and a display unit for outputting an image signal from said display controller to said display unit to display an image based on the image signal,

• wherein said display controller comprises:
• an input device adapted to receive an image quality adjustment designation, which includes a first or second image quality adjustment, for designating an image quality adjustment of an image to be displayed on said display unit, wherein the first image quality adjustment is performed in said display unit and the second image quality adjustment is performed in said display controller;
• a control circuit adapted to convert the first image quality adjustment to a command signal, in a case in which the input device receives the image quality adjustment designation including the first image quality adjustment;
• an image processing circuit adapted to perform an image processing on an inputted image signal, so as to adjust an image quality of an image to be displayed on said display unit based on the second image quality adjustment, and to output a processed image signal, in a case in which the input device receives the image quality adjustment designation including the second image quality adjustment;
• and
• an output device adapted to output, to said display unit, either (i) the command signal converted by the control circuit and the inputted image signal, or (ii) the processed image signal outputted by the image processing circuit, and
• wherein said display unit comprises:
• a receiving unit adapted to receive (i) the command signal and the inputted image signal, or (ii) the processed image signal outputted by the output device;
• an image quality adjusting circuit adapted to perform the first image quality adjustment on the inputted image signal received by the receiving unit, based on the command signal received by the receiving unit;
• and
• a display screen adapted to display an image in accordance with the image signal adjusted by the image quality adjusting circuit or the processed image signal.

An image display control method for outputting an image signal from a display controller to a display unit to display an image on the display unit, said method comprising:

• an input step of inputting an image quality adjustment designation that includes a first or a second image quality adjustment for designating an image quality adjustment of an image to be displayed on the display unit, wherein the first image quality adjustment is performed in the display unit and the second image quality adjustment is performed in the display controller;
• a command conversion step of converting the first image quality adjustment into a command signal, in a case in which the image quality adjustment designation including the first image quality adjustment is received in said input step;
• an image processing step of performing an image processing on an inputted image signal, so as to adjust an image quality of an image to be displayed on the display unit based on the second image quality adjustment, in a case in which the image quality adjustment designation including the second image quality adjustment is received in said input step;
• and
• an output step of outputting, to the display unit, either (i) the processed image signal processed in said image processing step or (ii) the inputted image signal and the command signal converted in said command conversion step.

A computer-readable storage medium storing a control program adapted to execute an image display control method for outputting an image signal from a display controller to a display unit to display an image on the display unit, the program comprising:

• an input-step module for inputting an image quality adjustment designation, which includes a first or a second image quality adjustment, to designate an image quality adjustment of an image to be displayed on the display unit, wherein the first image quality adjustment is performed in the display unit and the second image quality adjustment is performed in the display controller;
• a command-conversion-step module for converting the first image quality adjustment to a command signal, in a case in which the image quality adjustment designation including the first image quality adjustment is received by said input-step module;
• an image-processing-step module for performing an image processing on an inputted image signal, so as to adjust an image quality of an image to be displayed on the display unit based on the second image quality adjustment, in a case in which the image quality adjustment designation including the second image quality adjustment is received by said input-step module;
• and
• an output-step module for outputting from the display controller to the display unit either (i) the command signal converted by said command-conversion-step module and the inputted image signal, or (ii) the processed image signal processed by said image-processing-step module.

An image display control method for outputting an image signal from a display controller to a display unit to display an image on the display unit, said method comprising:

• an input step of receiving an image quality adjustment designation, which includes a first or a second image quality adjustment, to designate an image quality adjustment of an image to be displayed on the display unit, wherein the first image quality adjustment is performed in the delay unit and the second image quality adjustment is performed in the display controller;
• a control step of converting the first image quality adjustment to a command signal, in a case in which the image adjustment designation including the first image quality adjustment is received in said input step;
• an image processing step of performing an image processing on an inputted image signal so as to adjust an image quality based on the second image quality adjustment, in a case in which the image adjustment designation including the second image quality adjustment is received in aid input step;
• an output step of outputting from the display controller to the display unit either (i) the command signal converted in said control step and the inputted image signal, or (ii) the processed image signal processed in said image processing step;
• a reception step of receiving (i) the command signal and the inputted image signal, or (ii) the processed image signal outputted in said output step;
• and
• an image quality adjusting step of performing the first quality adjustment on the input image signal received in said reception step, based on the command signal, so as to display an image on the display unit.
