FIG. 6 is a block diagram showing a specific configuration of the reproduction application 24 operated by the projector of the present invention. Hereinafter, an example of a method of processing image data will be specifically described with reference to FIG. The reproduction application 24 includes a control unit 61 that controls processing of image data,
A resource data interface 6 connected to the network interface 5 and the RAM 6 for reading and writing image data between the server 32 (FIG. 3) and the RAM 6
2, a script interpreter 63 that processes an interactive script included in the image, and a video processing unit 64 that is connected to the VRAM 7 and processes digital video data.

Here, the control section 61 has an event entry section 61a, and is connected to the VRAM 7, the sound control section 9, and the I / O port 12. In the event entry section 61a, an event for performing a routine process such as an interrupt process is registered, and the event occurs according to an input signal input from the key input device 11 via the I / O port 12. The event is processed by the control unit 61.

Here, when an input signal from the key input device 11 is interactively input to the display screen and it requests processing of a script, the control unit 61 sets the event
In response to the generation of the script from the entry section 61a, the script interpreter 63 is called, the script interpreter 63 processes the script, and receives the execution result.

When the data to be processed is digital video data, the control section 61 controls the video processing section 64.
Is activated, and the video processing unit 64 performs the reproduction processing of the digital video data. The start and stop of the video processing unit 64 are controlled by the control unit 61.
A part of the data area of the control unit 61 is allocated to the data area. In addition, the clock timer of the control unit 61 and the clock timer of the video processing unit 64 are independent, and processing of each image data can be performed individually.

FIG. 7 is a flowchart showing the processing of the image data of the reproduction application 24 shown in FIG. As a precondition, image data is already prepared in the server. Here, an example of creating image data will be described. First, a plurality of still image files, digital video files, sound files, and the like are created, and a content for each image is created by these. A frame number is assigned to the plurality of created contents, and a table is arranged in a display order based on the frame number.
Create a control table (image control data). The control table and each image data are stored in the server.

In FIG. 7, first, the control section 61 downloads the control table from the server (701), and sets the first frame number of the image data necessary for reproduction to the frame number.
It is set on a counter (not shown) (702). next,
The control unit 61 checks whether the image data to be reproduced is in the RAM 6 based on the frame number via the resource data interface 62 (703). If there is no image data corresponding to the frame number in the RAM 6, the corresponding image data is downloaded from the server via the network interface 5 (704), and is downloaded to the RAM 6 via the resource data interface 62. Write (705).

Next, the control section 61 performs reproduction processing (generation and display of an image) of the image data corresponding to the frame number (706). At this time, the control unit 61 processes the data according to the type of data. If the data is sound data, the control unit 61 transfers the sound data to the sound control unit 9 and reproduces the data through the speaker 10. In the case of digital video data, the video processing unit 64 processes the digital video data, and the digital video data is transferred from the video processing unit 64 to the VRAM 7. The still image such as text and the moving image such as digital video transferred to the VRAM 7 are transferred to the projector display device 1 via the projector interface 14.
5 is displayed. When a key input is generated from the key input device 11 while processing and displaying an image, the control unit 61 checks whether there is a script corresponding to the event. If there is a script, the script interpreter 63 processes the script, receives the execution result, and executes a process according to the result.

When the reproduction (the generation and display of the image) of the image data of the frame number set in the frame counter is completed, a frame end event occurs. If this event requires script processing (70
7) The script is processed by the script interpreter 43 and the result is passed to the control unit 61 (708).
If the result of the script processing specifies a new frame number (709), the control unit 61 resets the frame number in the frame counter (710),
The reproduction operation of the image data is repeated until the display of all the images is completed (706 to 712).

On the other hand, when the frame end event does not require script processing (707), and when the script processing result does not specify a frame number (7
In step 09), the control unit 61 adds 1 to the frame number of the frame counter (711), and repeats the image data reproduction operation until display of all images is completed (706 to 706).
712).

Here, after the image data of the last frame number is reproduced, a script may be executed to repeat the display of the image from the first frame number, or to display a predetermined image. Good.

In the case of interactive script data, the control unit 61 includes a script interpreter 63.
, Receive the execution result, and execute a process according to the result. This process may be performed on the server. For example, script interpreter 6
If the execution result of Step 3 is a request for new image data, the control unit 61 requests the server to download new image data.

As described above, according to the method of reproducing image data in the projector of the present invention and the projector, the image reproduction processing is performed by the reproduction application including the browser 22 and the player 23, and the interactive script processing is performed by the script and Since the video data is processed by the interpreter 63 and the digital video data is processed by the video processing unit 64, and the reproduction function is divided according to the type of image data, the OS, the reproduction application, and the image data are stored. The capacity of the RAM 8 to be stored can be reduced, and the processing speed of the CPU 1 can be reduced.
