Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a map recording disk device that records various enlarged/reduced/Is maps on a video disk and randomly accesses a map at a desired address by a video disk playback device. A map is subdivided into matrix planes to partition macromaps, this macromap is subdivided in the same way to partition semimaps, and this semimap is subdivided in the same way to form micromaps. , an address function is defined for each of the micromaps, and the address values obtained from these address functions and the corresponding frame number information are stored in advance in the RAM of the discrimination circuit from the video disk, and the specified address on the display is Calculate the coordinate value with a discrimination circuit and calculate an address value that includes this coordinate value from the address function, or input the address value directly by key operation and find the number corresponding to this address value from the above address frame information. The map information stored in this frame on the display is generated as a still image, and in particular, an image taken from directly above or diagonally above is recorded on a video disc as a map.

Maps are sequentially recorded in the frames of a video disc, and each frame must include map image information as well as frame numbers adjacent to the map and frame numbers of enlarged/reduced maps, leading to an increase in video disc production costs.

In addition, the capacity of the memory that stores a huge amount of frame number information becomes large, which increases the complexity of the device and increases costs. The frame is designed so that only image information can be stored in the frame, and will be explained in detail below based on the drawings.

([) is a video disc examiner that projects image information recorded on a video disc on a display (2);
) is the controller that controls this disc playback device,
(4) is a discrimination circuit that supplies the frame number to be reproduced to the controller (3), which has the function of calculating the dot coordinate value, the function of calculating the address value of the map including the dot coordinate value from the address function, and the function of calculating the address value of the map including the dot coordinate value, and the function necessary for shifting. It has a function to calculate adjacent address values, a memory to store address values and corresponding frame number information necessary for these calculations, and a memory to temporarily store address values during menu-based searches. The keyboard (5) is equipped with function keys such as macro map, dot movement keys, shift keys, etc., and various input information is given to the discriminating circuit (4) by these operations.

Multiple unit maps to be recorded on a video disc are superimposed on a rectangular coordinate plane as shown in Figure 2, and subdivided into squares using equally spaced vertical and horizontal lines parallel to the coordinate axes to create 32 macro maps ( 6) to form sections. In order to specify this macro map (6), the code a1 is placed every 16 scales on the X axis.

This initial value address/frame information is stored in the memory of the discrimination circuit (4) from the video disc032
Each macro map (6) is subdivided into 16 equal parts to form a semi-map (7), and the address function is set to [a4

m is defined as a natural number including O. Figure 3 shows the macromap (6) whose address value is (&5o-a64/b3z~”16] subdivided into 16 semi-maps (force divisions), and the address of the semi-map (7) in the left corner of the bottom row. The value is [ass-a64/ boo-1) + s), and the right corner of the bottom row is (aso-a?6/ b32-bel) The semi-map (7) containing 11 points (P) is Cats-ayz/

Note that the n-times scales of the single scales al and bl are an, bn, which are used for the address values of maps (6), (7), and (8), and an and bm are the origin of the unit map. (Fig. 2), but it may also be understood as a symbol used in an address function. 8192
The memory of the circuit (4) determines the initial value of the frame number corresponding to the first address value. 0 to be stored in
The divided map t6), f force, (8) is not projected on the entire surface of the display (2), but an area divided by the four points A, B, and OSD on the display (2) as shown in Fig. 5. (that is, [an, bm] points match these four points), the adjacent maps (6), (force, (8)

The controller (3) selects a predetermined frame address from the disc playback device (1) and causes the display (2) to display the macro map (6).
figure).

In order to enlarge a part of this macro map (6), move the dot point furnace to the desired position and press the [semi] key, then the discrimination circuit (4) will change the coordinate values of the point (P) in the same way. Calculated, semi-map (force address value [a76 to a7) 1
)28-b24) is calculated, the frame containing this is selected, and a map is displayed on the display (2). Dot points (4 points A on the display (2))
If you position it outside the areas of B, C, and D and press the shift key, the macro map (6) containing point (P) will be
(4). [If you continue to press the shift key in this state, the macro map (6) will scroll and be displayed in sequence.

Semi-map (When you want to see a part of the force magnified in history, move the point (P) to that position and use the micromag.

. The discrimination circuit (4) determines that the address 1st shift is (a74-a73
/b27-b26) is displayed (Fig. 6). Position the point (P) outside the area of the four points A, B, C, and D, and the adjacent micromap +8 by pressing the shift key will be projected in the same way. If you press the [Macro] or [Semi] key here, this micro map (8
) can be projected by the discrimination circuit (4), and conversely, the micromap (8) can be projected immediately from the macromap (6).

Once the dot coordinate values are calculated, you can continue to display the dot at the corresponding position even if you move to another map.
For example, once you have entered the coordinate values on the unit map, you can create a map containing the dot coordinate values by simply pressing the [Macro], [Semi], or [Micro] function keys.
(8) is displayed on the display (2). By storing the address frame information in the ROM of the discriminator circuit (4), it is no longer necessary to input this information into the first frame group of the video disc, eliminating waiting time. This ROM
If you store the user registration frame information in advance,
A desired micromag (8) can be drawn out directly by keyboard operation. Address functions such as macromap (6) are naturally divided into (n++s) and (n+4) depending on the number of divisions.
), (n+1), etc., so the definition is not limited to the above, and a pointing device such as a touch panel may be used instead of the dot display.

Next, to explain the images of map i61, (7), t8), a simple map may be used, but the present invention, which uses video images taken from directly above or diagonally above, memorizes roads, river proboscises, etc. as they are. Because of this, it can be used as a data bank. By placing images taken diagonally from above in four directions next to a semi-map (7) taken from directly above, buildings and other objects can be observed in three dimensions, making it a great marketing tool.

As described above, the present invention subdivides the macromap (6) into semi-maps (7) or micromaps (8), defines address functions therein, and defines the address values obtained from each address function. Store the information of the corresponding frame number in memory and display it (2)
The specified coordinate value above is calculated by the discriminator circuit (4), and the address value including this is calculated from the address function, so there is no need to store information other than images in the frame of the video disc, and it is possible to enlarge the map, reduce the map, and scroll. The map access operation is extremely easy7; CY), which improves the performance of the entire system and reduces costs.
