Description

  The present invention relates to a display control apparatus and method, and a program, and more particularly to a display control apparatus capable of supporting output of various resolutions and aspect ratios without imposing a burden on an application for displaying graphics. And a method and a program.

  In recent years, displays have been increasing in size and definition, and displays with various resolutions have become widespread. Also, there are aspect ratios of 4: 3 and 16: 9.

  For example, a display used in a commercially available television receiver has a resolution of 640 × 480 pixels with an aspect ratio of 4: 3, and 1920 × 1080 with an aspect ratio of 16: 9. Some have pixel resolution.

  In order to deal with such various display resolutions, for example, an application that displays a menu screen or the like installed in a predetermined device has a graphic depending on the resolution of the connected television receiver (display). You need to change the resolution. Specifically, it is necessary to create and output high-resolution graphics for high-resolution displays, and low-resolution graphics for low-resolution displays. .

  Accordingly, if the screen display with various resolutions is handled only by the application as described above, it is necessary to regenerate graphics every time the resolution is different, and the processing load of the application becomes heavy. When one screen display is performed by a plurality of applications, work for recreating graphics is performed in each application, and a lot of resources are consumed.

  Therefore, even if the resolution changes, there is a need for a mechanism that can output graphics with different resolutions without the application being aware of the difference.

  The present invention has been made in view of such circumstances, and is intended to be able to cope with output of various resolutions and aspect ratios without imposing a burden on an application for displaying graphics. .

  The present invention provides an application / creation step for creating one type of image used for displaying graphics, and a graphics according to the display resolution or aspect ratio designated by a predetermined designation means. A module / output step for creating and outputting based on the image created in the step is provided.

  The module can generate graphics corresponding to the display by converting an image created by the application to a resolution having the same resolution as the display.

  The module can create a graphic corresponding to the display by cutting out and enlarging or reducing a predetermined range of the image created by the application.

  When the aspect ratio of the image created by the application is the same as the aspect ratio of the display, the module outputs the image created by the application as graphics corresponding to the display as it is, and the aspect ratio of the display is different In addition, by adding a letterbox to an image created by an application, graphics corresponding to the display can be created and output.

  The application creates an image with shapes that make it difficult for the user to notice the difference between looking at the details and looking at the whole, and the module creates a predetermined image of the images created by the application. By cutting out the range and enlarging or reducing the range, graphics corresponding to the display can be created.

  When there are multiple types of graphics aspect ratios to be output, the application creates an intermediate predetermined aspect ratio image that does not correspond to any aspect ratio, and the module creates an image created by the application with the display aspect ratio. By converting to the same aspect ratio as the ratio, graphics corresponding to the display can be created.

  In the present invention, one type of image used for displaying graphics is created, and graphics corresponding to the display is created and output based on the created image.

  According to the present invention, it is possible to cope with output of various resolutions and aspect ratios without imposing a burden on an application for displaying graphics.

  A CPU (Central Processing Unit) 11 executes various processes according to a program stored in a ROM (Read Only Memory) 12 or a program loaded from a storage unit 18 to a RAM (Random Access Memory) 13. The RAM 13 also appropriately stores data necessary for the CPU 11 to execute various processes.

  The CPU 11, ROM 12, and RAM 13 are connected to each other via a bus 14. An input / output interface 15 is also connected to the bus 14.

  The input / output interface 15 includes an input unit 16 such as a keyboard and a mouse, an output unit 17 for displaying graphics (graphics, characters, etc.) on an external display such as an LCD (Liquid Crystal Display), and a hard disk. And a communication unit 19 that performs communication processing via a network.

  A drive 20 is also connected to the input / output interface 15 as necessary. A removable medium 21 composed of a magnetic disk, an optical disk, a magneto-optical disk, a semiconductor memory, or the like is appropriately installed in the drive 20, and a computer program read therefrom is installed in the storage unit 18 as necessary.

  The display control apparatus 1 having such a configuration includes an application for creating an image used for displaying predetermined graphics such as a menu screen on which icons are arranged, and an output based on the image created by the application. A module for creating graphics according to the previous display is provided.

Example 1
FIG. 2 is a diagram showing a concept of graphics display performed by the display control apparatus 1.

  In FIG. 2, the application 31 creates a graphic image to be displayed at a predetermined resolution such as 960 × 540 pixels regardless of the resolution of the display connected to the display control apparatus 1, and draws it on the resource. . In other words, even when a display having a resolution of 720 × 480 pixels is connected or a display having a resolution of 1920 × 1080 pixels is connected, The resolution is a fixed type.

  The image creation by the application 31 is performed by placing an icon or the like stored in a database (not shown) at a predetermined position within a range of 960 × 540 pixels obtained by calculation. When the screen is moving, the image creation by the application 31 is repeated at a predetermined cycle.

  Based on the image created by the application 31, the conversion module 32 converts the resolution to the same resolution as the display, thereby creating graphics corresponding to the display. As shown in FIG. 2, the resolution of the display connected to the display control device 1 is specified in the conversion module 32.

For example, when the resolution of the display is 720 × 480 pixels, the conversion module 32 converts the image of 960 × 540 pixels created by the application 31 into that of 720 × 480 pixels as indicated by the tip of the arrow A _1. To create graphics.

In addition, when the display resolution is 1280 × 720 pixels, the conversion module 32 converts the image of 960 × 540 pixels created by the application 31 into one having 1280 × 720 pixels as indicated by the tip of arrow A _2. To create graphics.

Furthermore, when the resolution of the display is 1920 × 1080 pixels, the conversion module 32 converts the image of 960 × 540 pixels created by the application 31 into that of 1920 × 1080 pixels as indicated by the tip of arrow A _3. To create graphics.

  In this way, the processing is distributed by the application 31 and the conversion module 32 so that graphics are displayed, so that the application 31 creates an image of one type of resolution without being aware of the resolution of the display. Just do it. For example, if the application 31 creates an image according to the resolution of the display, it is necessary to recalculate, for example, the icon resolution and the position on the screen each time the display resolution is different. There is no need to perform such processing.

Example 4
FIG. 8 is a diagram showing another concept of graphics display performed by the display control device 1.

  In FIG. 8, the application 31 creates a graphic image to be displayed at a predetermined resolution such as 960 × 540 pixels regardless of the resolution of the display connected to the display control apparatus 1 and draws it on the resource. To do.

  Here, for example, the application 31 creates an image on which a self-similar figure is drawn so that it is difficult to notice the difference between when the details are enlarged and when the whole is seen.

  The conversion module 32 cuts out a predetermined range as indicated by a dotted line in FIG. 8 from the image created by the application 31, and scales the cut-out image appropriately according to the resolution of the display, thereby depending on the display. Create graphics.

For example, the conversion module 32 displays graphics in which a graphic having a range as indicated by the tip of the arrow A _{1 in} FIG. 8 and graphics having a graphic having the range indicated by the tip of the arrow A ₂ are displayed. According to the output.

  As described above, since a self-similar figure or the like is drawn on the image created by the application 31, a predetermined range is set according to the resolution and aspect ratio of the display from an image on which a figure or character that is not a self-similar figure is drawn. The user is less likely to notice the difference in the drawn content than in the case of cutting out and scaling up and displaying.

  As described above, even if the processing is distributed by the application 31 and the conversion module 32 so that graphics are displayed, the application 31 can display one type of image without being conscious of the resolution and aspect ratio of the display. Just create it.
