Description

  The present invention relates to an information processing device and a program, and more particularly to a technique preferably applied to display control of a display device having a plurality of displays.

  Conventionally, for example, a large-screen image is displayed using a multi-display configured by combining a plurality of display devices such as a CRT (Cathode-Ray Tube) and an LCD (Liquid Crystal Display), or the individual components constituting the multi-display are displayed. A multi-display system is known as a system for displaying different image data on a display device. Such a multi-display system provides an image for an individual user such as a portable game device having two displays at the top and bottom in addition to an environment for displaying an image to an unspecified number of users such as a stadium facility and an exhibition hall. It is also applied in the display environment. For example, Patent Document 1 discloses a multi-screen notebook computer that realizes a plurality of screens in various forms by displaying different data and contents on each display while storing a plurality of displays in the shape of a laptop computer in a compact manner. ing.

On the other hand, in a display device provided in a personal computer, a digital camera, etc., the display screen configuration is horizontally long by maintaining the display content (images and characters) in its original orientation even when the display screen is rotated 90 degrees or 180 degrees. There is known a technique for making display or portrait display usable according to user's preference. In addition, many mobile phones with a TV function recently provided on the market have been devised so that the video data can be viewed in a horizontally long display so that it can be viewed. For example, in Patent Document 2, when switching to vertical display or horizontal display in real-time display such as a TV image or a moving image display, the rotation angle is detected, and the display direction and display size corresponding to the rotation angle are set. Thus, a portable terminal that automatically switches to vertical display or horizontal display is disclosed.

  Next, display control processing by the information processing apparatus of this embodiment will be described. FIG. 4 is a flowchart showing a flow of screen display control processing in the information processing apparatus of the present embodiment. First, the information processing apparatus 1 acquires the slide state data detected by the slide detection unit 6 from the display device 5 (step S101). Next, the first display data generation unit 21 calculates the screen size of the entire screen using data (movement distance, position) regarding the slide state (step S102).

  Here, the whole screen is a screen formed by two displays after sliding, and is a combination of the screens of the portions that appear outside each display. As shown in FIG. 5, when the two displays are overlapped (sliding closed state), the entire screen size 51 is equal to the screen size of the first display. Further, in a state where the two displays have a portion that is exposed to the outside (slide open state), the entire screen size 52a is the sum of the exposed portions of each display.

  Returning to the flow, after calculating the screen size of the entire screen, the first display data generating means 21 compares the screen size of the entire screen with the screen size of the first display (step S103). By performing this comparison, it can be determined whether the display on two displays is necessary or the display on one display is sufficient. When the screen size of the entire screen is larger than the first display (step S103 / YES), the first display data generating unit 21 generates display data of the entire screen using the calculated screen size (step S104).

  Next, the second display data generation unit 22 extracts data corresponding to the screen size of the first display from the display data of the entire screen generated by the first display data generation unit 21, and generates the display data of the first display. (Step S105). Further, the third display data generating unit 23 extracts data corresponding to the screen size of the second display from the display data of the entire screen generated by the first display data generating unit 21, and generates display data of the second display. (Step S106).

  In the present embodiment, which part of the display data of the entire screen is used as the display data for the first display and which part is used for the display data of the second display is determined as follows, for example. As shown in FIG. 5B, when the display is slid by α to enlarge the screen size to the entire screen 52a, the display screen size 52c from the end on the enlarged side including this enlarged portion is set. It is set as display data of the second display. The display screen size 52b from the end opposite to the end on the enlarged side is used as display data for the first display.

  When returning to the flow, the display control unit 24 acquires display data of each display generated by the second display data generation unit 22 and the third display data generation unit 23, and generates a video signal and a control signal from the display data. Then, it is sent to the display device 5 (step S107). On the display device 5 side, the first display 7 and the second display 8 perform screen display based on video signals and control signals corresponding to the first display 7 and the second display 8.

  On the other hand, when the screen size of the entire screen is equal to that of the first display (step S103 / NO), the first display data generating unit 21 generates display data of the screen size of the first display (step S108). Then, the display control unit 24 generates a video signal and a control signal from the display data of the first display generated by the first display data generation unit 21 and sends it to the display device 5 (step S109).

  According to the above-described embodiment, since a plurality of displays are combined to form one desktop (or a display that displays a common screen), it is possible to save the display space. In addition, the display data of the entire screen (common screen) is generated according to the slide condition of the display and the display data of each display is generated.
