Abstract

PURPOSE:To display image information with dependancy on time after a desired forecast time, by displaying the image stored and read and moving the image to a prescribed direction. CONSTITUTION:When a power switch 5 is turned on, a picture clear data is transmitted from a CPU 6 to a display RAM 9 and a display unit 2 is at clear screen state. Next, a cutting of a weather map of a newspaper is read with an image sensor 1 and the image data read is written in a memory 7. After write, the CPU 6 transmits the data of the memory 7 to a display memory 9 and the weather map is displayed on the display unit 2. In case it is desired to see a weather forecast map after a desired forecast time, at each depression of ''arrow to the right'' key out of shift keys 4, the mode of a moving speed varying switch 3 is read and the information that the amount of shift to right is maximum is given to a memory controlling part 8 to shift the image data of the memory 7, allowing to display the weather map after the desired forecast time on the display unit 2.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an image information display device, and more particularly to an image information display device that displays image information that is time-dependent to be read, such as a weather map.

Devices that read time-independent image information and store it in a storage section under the supervision of an arithmetic and control unit (hereinafter abbreviated as CPU) and display this stored image information using predetermined display control are already common. be. It is also common to reproduce time-dependent image information using video, etc., but no device has been proposed that displays information on time-dependent image information after a certain amount of time. .

Consider, for example, a weather map as image information that is time-dependent and whose display content after a predicted time is desired to be known. Traditionally, in the case of a weather map published in a newspaper, etc., you can simply look at the weather map and make a rough judgment, such as whether the weather in 1 is likely to deteriorate or improve in the afternoon, and you can predict the weather in a few hours. It was difficult to predict.

The present invention has been made in view of the point L, and an object of the present invention is to provide an image information display device that is capable of displaying time-dependent image information after a desired predicted time.

Hereinafter, an example in which the image information display device according to the present invention is applied to an electronic weather map will be described.

FIG. 1 is a schematic plan view of this electronic weather map. In the same figure, a display board DB 1 includes an image sensor 1 that reads weather map clippings from newspapers etc. by optical means, and an image sensor 1 that reads the read image information. A display 2 is provided for displaying information. A transparent panel 2A is fitted into the front of the display 2, and a map of the vicinity including Japan, as well as meridians and latitudes, are written on the transparent panel 2A. A three-position switch 3 is provided on the display board DB (Nawate, also for changing the moving speed of image information read from the weather map, and depending on each slide position, there are fast, normal, and slow modes. Specifications can be made.

Further, on the display board DB are a movement key 4 for controlling the movement direction of image information and a power switch 5 for the entire device.
is provided. In the embodiment, the movement key 4 has a movement function in four directions. That is, "→" is a key for moving rightward, "←" is a key for moving leftward, "↑" is a key for moving -leftward, and "↓" is a key for moving downward.

FIG. 2 is a block diagram showing the electrical circuit configuration of the device shown in FIG. 1, and the same reference numerals as in FIG. 1 indicate the same parts. As mentioned above, the image sensor 1 reads weather map clippings from newspapers etc. and converts them into C as bit patterns.
It has the function of sending image data to PU 6. 7 is RA
M (lantern, access memory), CP
It has the function of writing and reading data sent from U6.

8 is a RAM control unit that controls RMi according to instructions from CPU 6.
In addition to controlling the write/read timing in step 7, the RAN 17 is controlled so that the image data displayed on the display device (to be described later) is in a predetermined moving direction and moving speed.

9 is a display illusion, and the RAM 7 to CPU
The image data to be read out is written and read out according to the instructions in step 6. Reference numeral 2 denotes the aforementioned display device which displays image information read out from the display RAM 9 via a decoder/driver (not shown). Further, information regarding the movement speed and direction of movement by the movement speed variable switch 3 and the movement key 4 is configured to be given to the CPU 6 as an external setting input.

One embodiment of the present invention is constructed as described above, and its operation will be explained with reference to the flowchart shown in FIG.

First, in step S1, when the power switch 5 is turned on, screen clear data is sent from the CPU 6 to the display RAM 9, and the display 2 is cleared as shown in FIG.
Screen status varies. Next, in step S2, a weather map clipping from a newspaper or the like is read by the image sensor 1. In step s3, the image data read from the image sensor 1 is written into the RAM 7 by the action of the CPU 6. After this write CPU 6
sends the data in RAM 7 to display RAM 9. In this state, it is assumed that the weather map review as shown in FIG. 5 is displayed on the display 2. Next, an explanation will be given of an operation method when, for example, after step s4, the user wants to view a forecast weather map for 6 hours later. Since it is now assumed that the weather changes quickly, it is assumed that the variable movement speed switch 4 is set to the fast mode in step s4. In step s5, when the [→] key of the movement keys 4 is pressed, the CPU 6 determines that the "+" key has been pressed and recognizes that the weather is moving to the right, and also changes the movement speed ijJ change switch 3. It reads the mode of
It is given to the M control section 8. Here, the image data in the RAM 7 is moved by the action of the R1 control section 8. Next, in step S6, the data of the RMi7 is transferred to the RAM 9 by the action of the CPU 6, and the weather map WP' for one hour later is displayed on the display 2 as shown in FIG. Similarly, in steps 87 to s16, the weather N for each hour is further displayed, and as a result, a forecasted weather map for 6 hours later can be viewed.

Also, if you want to know the course of the typhoon after the desired predicted time, for example, if it is heading northwest, you can use the ``↑'' key and the ``・-'' key of the movement keys 4 to find out the course of the typhoon after the desired predicted time. You can easily see the forecast weather map.

Therefore, if the electronic weather map according to this embodiment is incorporated into a hand-held device and used, it can be easily displayed no matter how many hours later the weather will be.

By using the electronic weather map listed in L, you can easily decide what to bring, what to wear, etc. according to the predicted weather conditions.
Destination etc. can also be determined in a way that reduces waste, making it extremely useful.

Although the embodiment described in 1-1 has been explained using an electronic weather map as an example, the present invention is not limited to the above embodiment, but the present invention is capable of controlling the display position of time-dependent image information after a desired predicted time. Applicable to those who

As explained above, the image information display device according to the present invention displays an image that has been read and stored, and can move the image in a predetermined direction (two directions). Display contents of certain image information after a desired predicted time can be realized, and it is extremely practical when applied to displaying image information such as electronic weather maps, for example.
