Description

  The present invention relates to display control of an information processing device that displays a plurality of screen data generated on a plurality of display devices.

  2. Description of the Related Art Conventionally, in presentations such as conferences and lectures, a format is used in which an image created by a computer is enlarged and displayed on a screen to create a screen for a listener. At that time, the image for the presenter and the image for the audience are the same, and when the presenter explained the displayed image, the presenter had to prepare a separate note for explanation. .

Patent Documents 1 and 2 propose a method of enlarging a part of a display screen and projecting only the area by a projector.
JP 2004-86277 A JP 2005-115093 A

  However, the methods described in Patent Documents 1 and 2 have a problem in that the image quality is lowered because an image obtained by enlarging a part of the display screen is projected by the projector.

  In addition, if the windows are minimized or overlapped, they are displayed as they are in the projector and cannot be displayed normally.

  In addition, there is a problem that it does not support full-screen display. Some slideshows of presentation software are premised on full screen display, and partial display is not possible when displaying on one screen. Therefore, there is a need for a device that can perform full-screen display within a small area on the desktop.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to display a screen corresponding to a part of the screen of the display device referred to by the operator as another display device such as a projector.

  The present invention provides an information processing apparatus that displays a plurality of screen data including first screen data generated on a plurality of display devices including a first display device, wherein the first screen includes the first screen. Combining means for combining screen data other than data, first display control means for displaying the first screen data combined by the combining means on the first display device, and any one of the screen data, And second display control means for displaying on a display device other than the first display device.

  According to the present invention, even when a screen corresponding to a part of the screen of the display device referred to by the operator is displayed on another display device such as a projector, the resolution or the like is lowered as in the past. The image quality can be maintained with high quality.

  Further, even when the window is minimized or the windows are overlapped on the display device referred to by the operator, the image corresponding to the window can be normally displayed on the other display devices. .

  Furthermore, there is an effect that it is possible to support full screen display.

Reference numeral 703 denotes an area to be created as a projection screen. Further, reference numeral 704 denotes a window that is displayed on the foreground and overlaps the projection screen 703 in the reference screen.

  In the conventional technique, a part of the reference screen 701 (here, 703) is cut out, enlarged to a size corresponding to the projection screen, and projected. Therefore, as shown in FIG. 21A, the image 702 projected on the projection screen has a poor image quality, and a part of the window 704 on the reference screen is also displayed.

  The present invention has a configuration in which the projection screen data 802 is reduced to an arbitrary position size in the reference screen 801 and displayed in the reference screen 801 as in 803. Therefore, as shown in FIG. 21B, there is no problem in the image quality of the image 802 projected on the projection screen (the image does not become rough as in the prior art). In addition, part of the window 804 on the reference screen is not displayed on the image 802.

  As described above, according to the present invention, a plurality of VRAM areas (areas for storing screen data) are secured on the VRAM, one for display display and the other for projector projection. Then, a reduced version of the screen projected by the projector is synthesized and displayed on the display screen. In addition, the VRAM area projected on the projector can be switched.

  According to the present invention, the resolution of the projection image can be maintained even when a part of the display screen is displayed. Further, even if the windows are minimized or overlapped, they can be displayed normally on other display devices.

  Here, it is assumed that the output key “VK_RIGHT (right cursor key)” corresponding to the input key “VK_NUMPAD6 (ten key 6)” is assigned to the setting key data 212 only in the VRAM area 2.

  For example, when “6” is input with the numeric keypad 905 of the keyboard assigned for the projection screen operation, based on the setting key data 212, the output key “VK_RIGHT (right cursor key) corresponding to the input key“ VK_NUMPAD6 ”is input. ) "Is transmitted only to the application corresponding to the VRAM area 2. Then, as shown at 902, only the VRAM2 area 903 transitions to a screen corresponding to “VK_RIGHT (right cursor key)”.

Reference numeral 1004 denotes an image corresponding to the VRAM 3 area in which the second projection screen data stored in a certain VRAM area is independently displayed at an arbitrary position and size in the reference screen. Reference numeral 1005 denotes an active window on the reference screen.

  Reference numeral 1006 denotes a numeric keypad portion of the keyboard allocated for the projection screen operation.

  In FIG. 23, it is assumed that the output key “VK_RIGHT (right cursor key)” corresponding to the input key “VK_NUMPAD6 (ten key 6)” is assigned only to the VRAM area 2 and the VRAM area 3 in the setting key data 212. To do.

  For example, when “6” is input with the numeric keypad 1005 of the keyboard assigned for the projection screen operation, the output key “VK_RIGHT (right cursor key) corresponding to the input key“ VK_NUMPAD6 ”is based on the setting key data 212. ) ”Is transmitted only to the application corresponding to the VRAM area 2 and the application corresponding to the VRAM area 3. Then, as indicated by 1002, only the VRAM2 area 1003 and the VRAM3 area 1004 are changed to a screen corresponding to “VK_RIGHT (right cursor key)”.

  The projector projection screen key operation processing operation will be described below with reference to the flowchart of FIG.

  FIG. 24 is a flowchart showing an example of the seventh control processing procedure in the present invention, and corresponds to the application assignment processing projector projection screen key operation processing in the present invention. Note that the processing of this flowchart is executed by the projector projection screen key operation processing diagram 208 shown in FIG. That is, this flowchart process is realized by the CPU 102 shown in FIG. 1 loading and executing a program stored in the external storage device 104 into the memory 110.

  First, in step S601, the projector projection screen key operation processing diagram 208 determines whether or not an arbitrary key has been input. If it is determined that no key has been input, the processing of this flowchart is terminated. Let

  On the other hand, if it is determined in step S601 that an arbitrary key has been input, the projector projection screen key operation processing diagram 208 proceeds to step S602.

  In step S602, the projector projection screen key operation processing diagram 208 refers to the setting key data 212, and in step S603, it is determined whether or not the input key operation is a key operation set in the setting key data 212. To do.

  If it is determined in step S603 that the input key operation is not the key operation set in the setting key data 212, the projector projection screen key operation processing diagram 208 directly ends the processing of this flowchart.

  On the other hand, if it is determined in step S603 that the input key operation is a key operation set in the setting key data 212, the projector projection screen key operation processing diagram 208 proceeds to step S604.

  In step S604, the projector projection screen key operation processing diagram 208 transmits an output key corresponding to the input key to an application corresponding to one or more assignment destination VRAM areas acquired from the setting key data 212. Then, the process of this flowchart is terminated.
