Abstract

PROBLEM TO BE SOLVED: To provide an image processor or the like which outputs an image on an arbitrary accurate scale. SOLUTION: A map is generated on a display picture (S1); and when two arbitrary points on this map are pointed via a keyboard, a mouse, or the like, these two points are displayed on the image and a distance L between two points on the image is detected (S2). When an actual distance D between these two points is inputted with the keyboard (S3), a reduced scale GSC of the map on the image is calculated by L/D (S4). When a desired reduced scale PSC is inputted with the keyboard (S5), a magnification for print is calculated by PSC/GSC (S6), and the image of the map is expanded with this magnification (S7), and a map on the desired reduced scale is printed by this expanded data.

However, exactly 1
It was not possible to print a map of any scale (in this case, scale) such as 1 / 10,000 or 1 / 50,000.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a block diagram showing the configuration of a "map processing device" which is an embodiment.

In FIG. 1, reference numeral 1 denotes a central processing unit CPU, which is connected to various devices described below through a bus line BL6 to control them. Reference numeral 2 is a keyboard KB, which has keys for cursor movement, general character input, and map creation / editing processing. Reference numeral 3 denotes a display LCD, which displays the map data written in the VRAM (4) which is a write-only memory for display.

Reference numeral 8 is a read-only memory ROM, which has a CP
It comprises a program PRG (8a) for controlling U1 and a FONT (8b) for storing a character pattern.

Reference numeral 9 is a write-only memory RAM, which is a non-volatile memory. The interior is divided into several parts, each of which is used for its own purpose. WO of RAM9
RK (9a) is a work area used to operate the above-mentioned program, IMAGE (9b) is an area for storing map data, and the map data is configured even if the entire map is an aggregate of dots. It may be good, or it may be a collection of line segments forming a map, and this embodiment can be realized by any method. Further, L (9c) is an area for storing the length on the memory when two points are designated on the screen, and this is multiplied by the length when printing one dot when the map has a dot system. It becomes the number of dots between the specified two points, and if you have the line segment method, the specified two
It becomes the length of the line segment between the points. D (9d) is an area for storing the actual distance designated by the operator. That is, it is necessary to indicate the distance between the two points and how much the actual length of the distance should be. This will show the scale of the map. GSC (9e) is an area for storing the scale on the memory. That is, it is a value obtained by dividing the L by D. PS
C (9f) is an area for storing a print scale. This value is input by the operator. M (9g) is an area for storing a magnification for enlarging a map on the memory.

Reference numeral 7 is a printer PRT for printing contents such as text. The present apparatus operates by the CPU 1 executing a program stored in the ROM 8.

Next, the operation of the present apparatus will be described with reference to the flow of FIG. 2 and the display screen example of FIG.

First, a map as shown in FIG. 3 is created on the screen (step S1). Since the method of creating a map can be implemented by existing technology, details are omitted.

After the map is created, two reference points are designated and displayed on the screen. In FIG. 3, for example, two points A and B indicating the length of the lower right building are designated by the keyboard 2 or a mouse (not shown) and displayed on the screen. The length between these two points is stored in L (9c) of RAM 9 (step S2).
For example, if the map is composed of dot images,
The size at the time of printing one dot is 1/10 mm, and if there is 40 dots between AB, it is detected as 4 mm and "4" is stored.

Next, the actual distances between the two points are input by the keyboard 2 and stored in D (9d) of the RAM 9 (step S3). For example, if the distance between AB is 20 m, it is converted into millimeters and "20,000" is input.

In this case, if the length of the building is known, the length may be input, but if it is not known, another reference point is selected and the length is input. For example, if the length of the bridge is known, points C and D in FIG. 3 may be designated and the length of the bridge may be input. In that case, the length of the bridge is the scale of this map.

The map scale is completed as described above. L to D
Divide by and store the value in GSC (9e) (step S
4). For example, in the above example, "1/5000" is stored at 4 / 20,000.

Then, the scale for printing is input. The scale of the map is usually 1 / 10,000 or 1 / 50,000, but it can be set freely. However, if the scale ratio is too large, the limit of the printing paper will be exceeded, and printing may not be possible. In extreme case, if you specify 1: 1, the map must be printed in the same size as it actually is,
It is impossible in practice. In this embodiment, the upper and lower limits of the scale are not set, but a common sense scale is input as the map. This value is stored in PSC (9f) (step S
5). For example, "1 / 10,000" is stored.

Next, the magnification at the time of printing the map data is calculated from the scale on the map and the printing scale. Ie IMAG
It is a magnification of how many times E (9b) is to be enlarged and printed. This is determined by dividing PSC by GSC. This value is stored in M (9g) (step S
6).

The IMAGE data is developed in WORK (9a) according to the calculated magnification (step S7).

In the example above, GSC is 1 / 5,000, P
If SC is 1/10000, M will be 1/2. In this case, the already stored IMAGE is reduced to half in distance and expanded to WORK (9a).

Further, the expanded data described above is printed (step S8).

Through the above steps, the map can be printed at a desired accurate scale.

As described above, according to the present invention,
Images of any exact scale can be obtained.
