Abstract

There is provided a multi-window display system that realizes simplified operation of window displays. Digital data selected more recently is displayed in a main screen window display section, and a plurality of subsidiary screen window display sections are displayed at progressively smaller sizes relative to the main screen window display section, which is displayed at the maximum size. Moreover, when a window display section is selected and a direction of movement is indicated, the selected window display section is moved in the indicated direction and displayed at an enlarged size. The size of the operation panel window display section corresponding to the selected one of the window display section is changed in accordance with the changing of the size of the selected one of the window display section. When one of the window display section is selected, the operation panel window display section corresponding to the window display section other than the one of the window display section selected by the selecting section is displayed semi-transparently.

Claims

1. A multi-window display control apparatus comprising:

a display control unit that controls a display device to display a plurality of windows in a display screen of the display device, the plurality of windows including a plurality of video windows and a plurality of operation panel windows corresponding to the respective video windows;

a selecting unit that selects one of the video windows; and

a control unit that is responsive to selection of one of the video windows by said selecting unit, for controlling said display control unit to display one of the operation panel windows corresponding to the one of the video windows selected by said selecting unit, in a different display mode from a display mode in which at least one of the operation panel windows corresponding to at least non-selected one of the video windows is displayed.

2. A multi-window display control apparatus according to claim 1, wherein the display mode for displaying the operation panel windows further comprises a semi-transparent display mode and a non-transparent display mode.

3. A multi-window display control apparatus according to claim 2, wherein, when another one of the video windows has been selected by said selecting unit following selection of the one of the video windows, said control unit controls said display control unit to change the display mode of one of the operation panel windows corresponding to another one of the video windows from the semi-transparent display mode to the non-transparent display mode.

4. A multi-window display control apparatus according to claim 2, wherein the semi-transparent display mode is executed by α

-blend processing relating to at least one of the operation panel windows and a background image.

5. A control method for a multi-window display control apparatus comprising:

a display control step of displaying a plurality of windows in a display screen, the plurality of windows including a plurality of video windows and a plurality of operation panel windows corresponding to the respective video windows;

a selection step of selecting one of the video windows; and

a control step of displaying, in response to selection of one of the video windows in said selection step, one of the operation panel windows corresponding to the one of the video windows selected in the selection step, in a different display mode from a display mode in which at least one of the operation panels windows corresponding to at least non-selected one of the video windows is displayed.
