FIG. 5A shows an arrangement of image data when the display screen size of the TFT module 3 is VGA (640 × 480 pixels), and FIG. 5B is generally used in a personal computer. Array of image data (BMP file data) stored in the storage medium, (c)
Indicates an array of image data of the storage medium 4 recorded according to the present invention. As is clear from FIG. 5B, the image data generally used in the personal computer is the image data from the left end (first column) to the right end (last column) of the bottom line (line 480) of the screen. Is recorded on the first line next to the header of the storage medium, and then the image data on the 479th line of the screen is recorded on the second line of the storage medium.
In this way, the image data is sequentially recorded up to the first line of the screen, that is, the image data is sequentially recorded on the storage medium 4 line by line from the bottom line to the top line of the screen. On the other hand, in the present invention, as is apparent from FIG. 5C, the image data is sequentially recorded on the storage medium 4 line by line from the top line to the bottom line of the screen. Details of this recording method will be described later.

FIG. 6 shows an example of an image recording format when a flash memory card is used as the storage medium 4. FIG. 6A shows the structure of the image header. In this example, the image header has an 8-byte structure, and the first byte is an image type indicating whether or not the image is a valid image, and the second byte is used. Indicates an image format (display screen size: VGA (640 × 480), SVGA (800 × 6
00), XGA (1024 × 768)), the third byte indicates the audio address (start address of the audio data in the most significant byte (in units of 8 blocks), the fifth byte specifies the pause time after the end of the audio, The sixth byte is normally reserved (reserved). However, when the LED character information is recorded on the storage medium 4, it indicates the start address of the LED character data.
The second byte is reserved.

FIG. 6B shows a memory structure (recording format) for one screen. In this example, one screen has four memories.
0 block, 1 block is 32 pages, 1 page is 52
Each block is composed of 8 bytes, and an 8-byte length header is provided at the head of each block. When the screen size is VGA (640 × 480), the total number of pixels is 6
Assuming that 40 × 480 = 614,400 and the total header amount is 8 × 37 blocks = 296 bytes, the image data capacity of one screen is 614,400 + 296, which is 1165 pages when divided by the byte amount 528 per page. . Therefore, when there is no error in each block, image data for one screen can be recorded in 37 blocks. When 40 blocks are allocated per screen, three blocks are left. Use as a spare.

FIG. 7 shows an audio recording format when the storage medium 4 is a flash memory card. FIG. 7A shows an audio header having a length of 4 bytes. The first byte indicates an audio type (whether it is valid audio or not).
The second byte indicates the data length of the audio data in page units (L
= 0-255), and the fourth byte indicates the data length (0-65535) of the audio data in 256-byte units (H).
Indicated by

FIG. 7B shows an audio recording format for one screen. As for audio data for one screen, one block is composed of 32 pages, one page is composed of 528 bytes, and the block length ( Number) is N (undefined), and a header is provided at the head of each block.

The reason why the audio data has a variable length will be described below. In this embodiment, the audio data to be recorded is a system for reproducing the WAV data of a personal computer as it is, for example, 8-bit PCM, frequency 1
1,025 KHz was adopted. In the case of this sampling, 8 bits X11,025KHzX60s in 1 minute
ec = 5292 K bits (661,500 bytes) is required. On the other hand, the read / write (W / R) unit of the flash memory card is based on one block (32 pages), and the number of blocks required for recording for one minute is 40 blocks, which is the same recording area as the image for one screen. However, considering the storage capacity of the flash memory card,
An audio recording area of one minute per screen cannot be secured. Therefore, the block length of the audio recording area is made variable for each image without securing a fixed area for the audio.

FIG. 8 shows the entire image and audio recording format. The image data is composed of 40 blocks (1280).
Page), one flash memory card is provided with 16 screens as an image recording area, and an audio recording area is provided following the image recording area. Variable length of audio data per image from 1 to 352 (block length undefined)
, And a total of 16 screens (audio number 1 to audio number 16) are provided. The LED character display data area is reserved (reserved) after the voice recording area.

(1) First, header data is read from the flash memory card 4 for a predetermined number of bytes (for example, 8 bytes), and the following processing is performed. (A) Confirm that the header is valid. (B) If it is valid, perform the subsequent processing. If invalid, the start address of the next image is set, and the process returns to (a). (Note that after the 16th image, the process returns to the start address of the first image.) (C) The audio start block address is set to R in the microcomputer 21.

(16) Return to step (1).

Next, the flow of signals from the VRAM 25 to the TFT module 3 will be described. (1) The VRAM read address is reset by a read start address reset signal generated by the VRAM read timing generator 23d of the graphic controller 23.

(2) VRAM read timing generator 23

(4) The read data is displayed on the display screen of the TFT module 3 according to the sampling clock.

(5) Steps (2) to (4) are sequentially repeated in the horizontal direction from the upper left position of the display screen of the TFT module 3 for a predetermined time (approximately 16.7 m).
In s), one screen is displayed.

(6) Return to step (1).

By operating the mode switch 9, the image display by the TFT module 3 can be switched between the automatic display mode and the manual display mode. In the automatic display mode, T is controlled by the microcomputer 21.
Images are automatically switched and displayed on the display screen of the FT module 3 at regular time intervals. On the other hand, in the manual display mode, the image can be displayed on the display screen of the TFT module 3 in a forward or backward direction by operating the step switch 7 one by one.

Further, when the speaker 15 is turned off by operating the switch-equipped volume 11, the screen is switched at regular intervals (for example, every 5 seconds), while the audio data is stored in the content (the audio recording area corresponding to the displayed image). During that time, the screen is held until the audio data ends.

As is clear from the above, in the present invention, T
Since the display of an image on the display screen of the FT module 3 is limited to a function of only displaying a still image, expensive hardware such as a personal computer or a CPU board capable of high-speed processing is not required as a control device, and computational performance is not required. Inexpensive components such as low one-chip microcomputers can be used. In addition, when an arithmetic unit (microcomputer) having such a low processing performance is used, the screen switching speed becomes slow. However, in order to cover this, the display screen is switched by a personal computer or the like (from the bottom of the screen to the top). Contrary to (rewriting), rewriting is performed so that the previous screen is left and overwritten from top to bottom of the screen. As a result, it is possible to avoid unnaturalness that occurs when the screen is slowly switched from bottom to top. Further, since the image data is recorded on the storage medium 4 (flash memory card) in a state where the image data is converted into a form to be written into the video memory 25, the image data from the storage medium 4 to the video memory 25 can be transferred to the video memory 25 even if a low-speed arithmetic unit is used. Data can be written at a relatively high speed, and the display speed in the TFT module 3 can be increased.

Further, the graphic controller 23 of the present invention outputs the image digital data read from the storage medium 4 to the TFT module 3 as it is without converting the image digital data into analog data and displays the image. In addition, a clear image can be displayed without signal deterioration due to data conversion.

Further, the graphic controller 23
When the image digital data read from the storage medium 4 is divided into RGB digital signals and stored in the video memory 25, R (red) and B (blue) are 5 bits and G
(Green) is stored in 6 bits. By setting G (green), which has high visual sensitivity, to one bit more than R (red) and B (blue), a 16-bit display (65,000) is stored. A thousand colors)
However, it is possible to reproduce a color sensation closer to full color (16,770,000 colors).

Further, since audio data is recorded together with the image data in the storage medium 4 and the data indicating the address of the audio data is inserted in the image data header.
When reproducing image data, audio data can be reproduced in synchronization. In this case, since the pause time is inserted in the audio header, the screen can be displayed for a certain time even when there is no or short audio announcement (data). Embodiment 2 FIG.

FIG. 9 is a front view and a side view of an image electronic POP device according to Embodiment 2 of the present invention, and FIG. 10 is a block diagram of a control circuit thereof. This Embodiment 2

As shown in FIG. 10, the LED character display device 53 has an LED display panel 55 for displaying characters.
And an LED driver circuit 57 connected to the microcomputer 21 for displaying character information (character digital data) read from the storage medium 4 on the LED display panel 55.

Next, the operation of the second embodiment will be described. Under the control of the microcomputer 21, the image data, audio data, and LED character data recorded on the storage medium 4 are read by the reading device 5, and the image is displayed on the display screen of the TFT module 3 by the graphic controller 23, and is displayed on the display image. Synchronously, the sound is reproduced from the speaker 15 by the sound reproducing circuit 33,
Characters are displayed on the LED display panel 55 by the LED driver circuit 57. Here, the reproduction of the image and the sound is as described in the first embodiment.
Regarding the display of the ED character data, the microcomputer 21 accesses the LED character data address of the storage medium 4 from the data indicating the LED character data number (address) in the image data header, and records the LED recorded therein. The character data is read, and the LED driver circuit 57 is driven to display characters on the LED display panel 57.

In the second embodiment, the microcomputer 21
Is controlled by the output signal from the human body sensor 51 as follows.

When no output signal is output from the human body sensor 51 (ie, when a human is not within a predetermined distance), the microcomputer 21 controls the LED driver circuit 57 to read the character information read from the storage medium 4. The display characters are displayed on the LED display panel 57 so that the display characters are moved and displayed, that is, flown. When the human body sensor 51 detects that a human has entered a predetermined distance, the microcomputer 21 controls the LED driver circuit 57 based on an output signal from the human body sensor 51,
To stop the flow of the character display on the display panel 55,
Either dimming the LED or turning off the LED to stop displaying characters.

The microcomputer 21 may control the display of the TFT module 3 based on the output of the human body sensor 51.
