According to the retrieval apparatus of the present embodiment, images and explanations can be displayed simultaneously, and furthermore, automatic display can be performed automatically in order to reduce the complexity of key operations by the user. Also, within the same item, the image can be displayed all the time even if the explanation is scrolled.

Hereinafter, the details of the display control operation of the search device according to the present embodiment will be described. First, FIG. 5 shows an implementation flow of the present embodiment. First, in FIG. 4, the input screen (4-
After inputting a search word in 6) and starting a search (4-7), a corresponding list (4-8) is displayed. When a corresponding item is selected from the list, the explanation is displayed (4-9). In the explanation display (4-9), 8 cm CD-R before display
The description data read from the OM 17 is stored in the LCD 14
(5-portion) so that it can be displayed on the (display section 19).
1) Yes. The reason for the shaping is that the data of the read explanation is a long character string, so that it is necessary to make it easy to see. Conventionally, after the shaping (5-1), the shaped data is directly displayed (5-9). (The shaping (5-1) and the description display (5-9) are collectively referred to as a description display (4-9).)

In the present embodiment, after shaping the data of the description (5-1), it is determined whether or not the shaped data includes an icon indicating an image (5-2).
If there is no icon indicating an image here, the formatted data can be displayed as it is, as in the past,
The display (5-9) is performed in that state. When the icon indicating the image is included in the data of the explanatory text after the formatting, the image address is stored (5-3), and the data of the explanatory text that has been formatted to secure a space for displaying the image is rewritten. Perform shaping (5-4).

The reason for reshaping is that the data obtained by shaping the explanatory sentence data in the shaping (5-1) is shaped so as to just fit the LCD 14 (display unit 19). 19) The whole image is displayed. Then, the display space of the image to be displayed is lost. further,
When shaping the data of the explanatory note by shaping (5-1), L
It is shaped according to the size of the CD 14 (display unit 19) of 50 half-width horizontal characters and 10 vertical lines, but when re-shaping (5-4), 25 half-width half-width characters corresponding to half of this are used.
It is reshaped so that it is 10 rows long.

When the data of the description is reshaped, the image data is read from the disk based on the address data of the image stored in the image address storage (5-3) (5).
-5). Then, the read image data is reduced to 75% of the original size (5-6). Here, the reason why the image is reduced to 75% is that the read image data is
(Display unit 19) size (256 dots x
This is because it is necessary to reduce the size of the LCD 14 (display unit 19) to half the size (200 dots × 200 dots), which is the display size of the image during simultaneous display.

When the read image data is reduced (5-6), the reduced image data is displayed on the left half of the screen (5-7). Then, after the image is displayed (5-7), the display position is set (5-8) so that the re-formatted description data is displayed on the right half of the screen, and the description data is displayed. Is displayed (5-9) at the position set in (5-8). With this series of operations, the simultaneous display of the image and the explanatory note ends. In this state, the user can use a function which can be used when only the explanation such as scrolling is displayed for the explanation while the image is displayed. FIG. 6 shows a display example of this simultaneous display screen. The display example of the screen of FIG. 6 simultaneously displays a description and an image of Tyrannosaurus.

Here, a supplementary explanation of the image reduction described in this operation will be given. 8cm CD-
The size of the image data recorded in the ROM 17 is 256 dots × 200 dots as described above. In an electronic book player as a search device, since one dot corresponds to one bit in image data, 256 dots × 20
In the case of 0 dot, it is 256 bits × 200 lines. The 256 bits in the horizontal direction (X direction) are the lower 1 bits of the 4 bits.
The bit sum of the bit and the lower 2 bits is calculated, and the operation result is used as the data of the lower 2 bits, and the lower 1 bit is deleted. By performing this for 256 bits, the data is reduced to 200 bits. In addition, in the 200 lines in the vertical direction (Y direction), the bit sum is obtained for all the bits in the last two lines of the four lines, the operation result is regarded as one line, and the remaining one line is deleted. And
When the data is packed, it becomes 150 lines, and is reduced to 75% in both the X and Y directions. The reason why the bit sum is calculated in the above-described method is to increase the amount of information as much as possible. FIG. 7 shows steps of such image reduction.

As described above, the simultaneous display of the explanatory note and the image has been described. However, when the explanatory note and the image are simultaneously displayed as shown in FIG.
By pressing the character enlargement key 35 shown in (1), the image can be displayed in the original size. FIG. 8 shows an operation flow at this time. When the image and the description are displayed simultaneously (8-1), it is determined whether or not the character enlargement key has been pressed (8-2). If the button has not been pressed, the display returns to the simultaneous display of the image and the explanation (8-1) and the state is maintained.
When pressed, the image data is read from the 8-cm CD-ROM 17 based on the address data of the image (8
-3). Then, save the current screen data (8-4)
And writes the read image data in the center of the screen (8-
5). With this method, the image displayed simultaneously by one key operation (pressing the character enlargement key) is displayed in the original size on the LCD.
14 (display unit 19). To return to the simultaneous display state after the image is displayed in the original size, the image can be returned by pressing the NO key of the YES / NO key 33 shown in FIG. In this case, the current screen data can be returned only by writing out the screen data saved in the save (8-4).

When the explanation is scrolled during simultaneous display of the screen and the explanation, and there is an icon indicating another image in the explanation of the same item, only the image data is automatically displayed. Update. Similarly, when you scroll,
When the description of a different item is reached, the simultaneous display of the image and the description is automatically canceled. FIG. 9 shows the flow of these operations.

FIG. 9 is a flowchart showing the operation of the previous stage of FIG. First, it is determined whether the image and the description are being displayed simultaneously (9-1). If not, the process shifts from A to FIG. If they are being displayed at the same time, it is determined whether or not the same item is a description (9-2). If it is determined that the item is a different item, the data of the explanatory note is formatted as the explanatory note data shown in FIG.
The shaping (9-3) is performed in the same manner as the reshaping in 1), and the explanation is displayed (9-11). If it is determined in the determination (9-2) whether or not the description is the same item, it is determined whether or not there is an icon indicating an image different from the image displayed in the description (9-4). . If they are the same, the shaping (9-
Perform 5), set the display position of the explanatory note (9-6),
Display (9-11).

If it is determined in step (9-4) whether or not there is an icon indicating an image different from the image displayed in the description, the address of the image is stored (9-).
7) Based on the address, 8cm CD-ROM
The data is read from 17 (9-8). Then, the image data is reduced (9-9), and the reduced image is displayed on the left side of the screen (9-10). Then, as in the case of FIG. 5, the description is reshaped (9-5) in the same manner as the reshaping (5-4) of FIG. 5, and the display position of the description is set (9-6).
Then, display (9-11) is performed. By performing such an operation, when scrolling is performed during simultaneous display of an image and a description, automatic cancellation and automatic display of another image of the same item can be performed.

In the above-described retrieval apparatus according to the present embodiment, an example has been described in which simultaneous display is performed using a combination of an image and a description. However, the present invention is not limited to this. When there is an icon, a sound may be automatically sounded when the explanation is displayed.
