Description

  The present invention relates to a display processing device, a display processing method, and a display processing program in which display processing in a display device of an in-vehicle electronic device is improved, for example.

  In recent years, in-vehicle electronic devices have become more and more multifunctional, and the recording media that can be used are not only for audio such as CD and MD, but also for video such as DVD and CD-ROM. . At the same time, in-vehicle electronic devices equipped with a relatively large display so as to be able to display TV and DVD images, rather than a conventional display only with function display (display device), are becoming common.

  Such a multi-function electronic device realizes each function by a dedicated electronic circuit, and has a basic configuration similar to that of a personal computer, and has a plurality of preinstalled application programs (hereinafter simply referred to as applications). ) Is shifting to a general-purpose one that can be used by switching on the OS. For this reason, for example, devices having an e-mail function by e-mail software, a web page browsing function by a browser, and the like have been developed, and an image corresponding to each application is displayed on the display according to a user's selection operation. It is configured to be displayed.

  Display processing in such an in-vehicle electronic device and the hardware for it are the same as in a personal computer. Image data read by a CPU is converted into RGB data for each pixel in a video memory (VRAM) of a graphic card. The display controller reads the RGB data from the VRAM one pixel at a time, sends the read RGB data to the display (A / D conversion according to the display), and displays the image. It has become.

Therefore, in the following description, virtual circuit blocks that realize the functions of the present invention and the present embodiment are used.

[Constitution]
[overall structure]
First, the display processing apparatus (hereinafter referred to as “this apparatus”) in this embodiment generally displays a background image corresponding to an application as a background of an image (application image) for an application program that has been installed in advance. By switching only this background image in various ways, it is intended to achieve both fun and entertainment and ensuring application functions, and includes the following elements shown in the functional block diagram of FIG. ing.

  In other words, the illumination detection unit 1 is connected to an illumination lamp switch of an automobile (referred to as a host vehicle) on which the present apparatus is mounted, and is means for detecting ON / OFF of the illumination lamp. The external data acquisition device 2 is means for acquiring image data from a recording medium. For example, a disk drive (CD-ROM, DVD-ROM, etc.), a reader / writer for flash memory (smart media, compact flash (registered trademark)) , Microdrive, memory stick, SD card, multimedia card) and the like. The main CPU and its peripheral circuit 3 are parts that serve as a control circuit for controlling the entire apparatus.

  The HDD control unit 4 is a means for reading various data such as an OS, application programs (including application images), and background images recorded on a hard disk (mass storage device). In this apparatus, a plurality of background images are stored in association with each application program. The application program and the background image can be input from the external data acquisition device 2 in addition to those recorded in advance by default. In other words, a user can install a desired application from a CD-ROM, and image data created, obtained (via a communication network, etc.) and processed in a personal computer, and image data taken with a digital camera are stored in a flash memory. It can be stored and used as a background image. As described later, when registering a background image in this way, an interface that allows selection of an application, selection of the display order of a plurality of background images, and input of a switching time by performing menu display or list display. May be prepared.

  The SDRAM 5 is a synchronous dynamic RAM for loading a program necessary for executing this apparatus. Therefore, the OS and necessary application programs (including application images) are loaded into the SRAM 5 and interpreted and executed by the main CPU and its peripheral circuit 3. The display 6 is a device that displays various types of information such as application images and background images, and a display device such as a liquid crystal display or an organic EL display can be used. The input unit 7 is a part for a user to input information such as a command from a switch or the like. The input unit 7 includes a touch sensor function, a remote control unit, an infrared transmission / reception unit, and the like, but is preferably configured integrally with the display 6 as a touch panel. . The VRAM 8 is a video RAM in which image data displayed on the display 6 is drawn by the main CPU and its peripheral circuit 3.

[Main CPU and its peripheral circuits]
Further, the main CPU and its peripheral circuit 3 are configured to realize the roles as the following parts shown in FIG. 1 by the operation of the program as described above. That is, the application identification unit 31 is a means for determining an application to be executed. The image acquisition unit 32 is a means for acquiring a displayed application image and a background image associated therewith. The image generation unit 33 is a unit that generates and outputs an application image with the background image acquired by the image acquisition unit 32 as a background. The output data is drawn in the VRAM 8 described above, but this drawing processing procedure is not limited to a specific one. For example, after drawing the background image, the application image may be drawn in the application display area, or the image obtained by combining the background image and the application image may be drawn sequentially. Also good. The setting storage unit 34 is a means for storing a setting time for determining the timing for switching the background image. For this set time, the user can input a desired value from the input unit 7.

  The background image switching unit 35 is a means for outputting a background image switching instruction in accordance with the switching timing of a plurality of background images corresponding to each application. The morphing processing unit 36 is means for performing a morphing process for switching the background image when the illumination detection unit 1 detects that the illumination lamp is OFF. This morphing process is generally realized by gradually displacing the control points associated in advance and gradually switching the brightness, color tone, design, etc. of the image. Anything that can be realized now or in the future is applicable. Further, since the processing is performed on the background image, strict morphing is not always required, and the processing speed may be increased and the processing load may be reduced by omitting some processing.

[Action]
An example of the display process according to the present embodiment as described above will be described with reference to the flowcharts of FIGS. In the following processing, selection, input operation, and the like by the user are performed via the input unit 7, and menu display, list display, application image display, background image display, and the like are performed on the display screen of the display 6.

[Background image registration]
First, background image registration processing will be described with reference to the flowchart of FIG. That is, when a user inputs a background image registration request corresponding to an application according to a menu display or the like (step 201), a list of available applications is displayed (step 202). When an application for registering a background image is selected by the user from the list (step 203), it is determined whether there is background image data prepared in advance by the user (step 204).

  If the image data exists outside the apparatus, such as a CD-ROM or flash memory inserted into the external data acquisition apparatus 2 (step 205), the list is acquired and displayed (step 205). 209). If the image data exists inside the apparatus, such as a hard disk (step 206), the list is acquired and displayed (step 209). If there is no image data prepared by the user (step 207), a list of background images registered by default is acquired and displayed (step 209).

  The user selects one or a plurality of background images corresponding to the application from the displayed list (step 210). When a plurality of selections are made (step 211), the display order is also selected and input (step 212). The display order may be selected by inputting the display order for each background image. The selected order may be automatically set to the display order. Further, when a plurality of selections are made, a desired switching time is also input (step 213). For this input, either a time indicated by a radio button or the like may be selected, or a specific numerical value may be input. After performing the above processing for all desired applications (steps 214 and 202 to 213), the registration processing is terminated.

[Application image display processing]
Processing for displaying the background image registered as described above according to the application will be described with reference to the flowchart of FIG. That is, when the user performs an operation such as selecting an icon of a desired application, the selected application is activated (step 301). Then, the application identifying unit 31 identifies the application, and the background image associated with the application image is acquired by the image acquiring unit 32 (step 302). Then, an application image with the acquired background image as a background is generated by the image generation unit 33 (step 303), and is drawn in the VRAM 8, so that it is displayed on the display 6 (step 304).

  When there is a single registered background image (step 305), application images with the same background image as the background are continuously displayed (steps 306 and 310). When there are a plurality of registered background images (step 305) and the time measured by the timer included in the main CPU and its peripheral circuit 3 has passed the time set in the setting storage unit 34 (step 307), Since the background image switching unit 35 instructs switching to the background image of the next order, an image corresponding to this is acquired, generated, and displayed (steps 308 to 310). When an instruction to start another application is input (step 309), an image corresponding to the newly started application is displayed in the same manner as described above (steps 301 to 310). The above processing is performed until the user inputs the end of the application (step 310).

[Morph display processing]
A process for performing morphing when switching the background image will be described with reference to the flowchart of FIG. That is, in the above processing, when the background image is switched according to the set time or when the background image corresponding to the newly started application is switched (step 401), the image acquisition unit 32. Thus, the background image to be displayed next is acquired (step 402). Then, the illumination detection unit 1 detects the state of the illumination lamp (step 403). When the illumination is ON, the morphing processing unit 36 does not perform morphing and draws and displays the next background image (step 403). 405). Along with the display of such a background image, an application image is acquired by the image acquisition unit 32 (step 406), and the application image is drawn and displayed in the application area (step 407). Thereby, the background image is switched together with the switching of the application.

  On the other hand, when the illumination is OFF (step 403), the morphing process is performed by the morphing processing unit 36 based on the newly acquired background image and the current background image (step 404), and the generated background image is displayed. Drawing and display are sequentially performed (step 405). Along with the morphing process of the background image, an application image is acquired by the image acquisition unit 32 (step 406), and the application image is drawn and displayed in the application area (step 407). Thereby, the background image subjected to the morphing process is displayed together with the application switching. When activation of another application is instructed (step 408), the processing from step 401 onward is repeated, and the display processing ends when the application ends (step 409).

  Examples of background image morphing display screens corresponding to such application switching are shown in FIGS. That is, for example, the application image is immediately switched from the display screen of the e-mail software to the menu display screen as shown in FIG. 6 as shown in FIG. On the other hand, the background image gradually changes as shown in FIGS.

[effect]
As described above, according to the present embodiment, a background image corresponding to an application is prepared, and the background image is assigned to each application. Therefore, compared to a case where the application is displayed on a full screen, the fun and entertainment are increased. be able to. Further, since a desired background image registered in advance by the user can be displayed, customization according to the user's preference is possible and display according to the atmosphere in the vehicle is possible. In addition, since a plurality of background images registered for each application are switched and displayed at a desired time interval set by the user, a screen that does not get tired even when used for a long time can be presented.

  Furthermore, since only the background image is changed, it is possible to prevent the visibility from being impaired without hindering an application image such as an e-mail or a browser. In particular, by performing morphing processing, it is possible to provide the enjoyment of changing the background image, but this is also performed only on the background image, and does not hinder the application image. Further, when illumination is on (when the interior of the vehicle is dark), such as at night, the morphing process is not performed so that the driver who is traveling is not deprived of changes in the image, so safety is improved.
