Display control apparatus and display control method

An image control apparatus, converting a resolution of input image signals and outputting the image signals to a display apparatus, comprising:

• a resolution detecting unit configured to detect the resolution of the input image signals;
• a screen-size acquiring unit configured to acquire a screen size of the display apparatus;
• a display-size control unit configured to control a display size of images displayed in the display apparatus;
• and
• a scaling unit configured to convert the resolution of the image signals,
• wherein, if the resolution of the input image signals is changed, the display-size control unit controls in such a manner that the larger an amount of change in the resolution is, the smaller the display size after the resolution change becomes, and in such a manner that the greater the viewing distance is, the larger the display size after the resolution change becomes.

An image control apparatus, converting a resolution of input image signals and outputting the image signals to a display apparatus, comprising:

• a resolution detecting unit configured to detect the resolution of the input image signals;
• a timer unit configured to measure a viewing duration;
• a display-size control unit configured to control a display size of images displayed in the display apparatus;
• and
• a scaling unit configured to convert the resolution of the image signals,
• wherein, if the resolution of the input image signals is changed, the display-size control unit controls in such a manner that the larger an amount of change in the resolution is, the smaller the display size after the resolution change becomes, and in such a manner that the greater the viewing distance is, the larger the display size after the resolution change becomes.

An image control method, converting a resolution of input image signals and outputting the image signals to a display apparatus, comprising the steps of:

• detecting the resolution of the input image signals;
• acquiring a viewing distance between a viewer and the display apparatus;
• and
• controlling a display size of images displayed in the display apparatus, the controlling step controlling,
• if the resolution of the input image signals is changed, in such a manner that the larger an amount of change in the resolution is, the smaller the display size after the resolution change becomes, and in such a manner that the greater the viewing distance is, the larger the display size after the resolution change becomes.

An image control method, converting a resolution of input image signals and outputting the image signals to a display apparatus, comprising the steps of:

• detecting the resolution of the input image signals;
• measuring a viewing duration, which is a time from when the image control method is started to when a change in the resolution of the input image signals is detected or a time from when a change in the resolution of the input signals is detected to when a next change in the resolution of the input image signals is detected;
• and
• controlling a display size of images displayed in the display apparatus, the controlling step controlling,
• if the resolution of the input image signals is changed, in such a manner that the larger an amount of change in the resolution is, the smaller the display size after the resolution change becomes, and in such a manner that the greater the viewing distance is, the larger the display size after the resolution change becomes.
