Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a human-powered computer device for inputting images.
When inputting predetermined image information including figures, graphs, etc., and saving it to internal memory or even external memory such as a floppy disk, the input means to the computer are usually keys 7I5-)" input, Typical methods include TV camera input, tablet (digitizer) input, etc. First, keyboard input is a method in which the image to be input is sequentially filled in the dot matrix displayed on the CRT'J display using keys manually. Although this method can maintain good image quality, it takes a huge amount of time to input.However, in the case of TV77 camera input, the original image is captured with an ITV camera, and the image information is recorded in chronological order. This method takes out the dust as an electrical signal, performs specified signal processing on a computer, and stores it at a specified address.This method, in principle, requires a short input time, but due to variations in illuminance, spots and dirt may be generated. Currently, it takes a long time to correct this.Furthermore, tablet input requires writing images such as characters on the input surface, which not only takes a long time to input, but also requires a conversion program. However, there is a drawback that input is not easy.

As described above, all of the conventional image input means have the disadvantage that it takes a long time to input, and that the input method is easy and requires a lot of effort.

The present invention has been made to overcome the drawbacks of the conventional art, and its purpose is to input images into a computer easily and in a short time, and to do so without degrading the image quality. To provide a computer input device that can be used with and.

Another object of the present invention is to provide a computer that can input such an image by scanning reading that performs pixel decomposition, similar to existing devices such as automatic plate making and Iso's original reading means, which is easier to handle and can be constructed at a lower cost. Provides input devices.

In order to achieve the above object, the present invention is applied to an input device for inputting images such as characters, figures, graphs, etc. to a computer, and its main configuration is as shown in the block diagram of FIG. An address designation indication A1 extending from a plurality of lot lines dividing the area, and this address designation indication A,
an input sheet 1 having an image display A2 drawn therein by means of display means having properties different from the partition lines, such as means for distinguishing each block, such as the type of color, the presence or absence of magnetism, the width of the display line, and the shade of the display; , is equipped with a reading means 2 for separately reading the address number and the presence or absence of an image in an arbitrary address area of this input sheet 1, and the output signal of this reading means is sent to a computer 3.
The feature is that the input is made to the .

Below, preferred embodiments that further embody the present invention will be described in detail with reference to the drawings.

Embodiment 1 exemplifies a document reading means, such as an automatic plate making machine, which has a scanning reading function that performs time-series pixel resolution.

First, FIG. 2 shows a schematic configuration diagram of an input device according to the present invention. Reference numeral 10 denotes a rotating drum in a document reading means of an automatic plate making machine, which rotates at a constant speed in the direction of arrow H1. The input sheet 1 is wound around the circumferential surface of the rotating drum 1o. On the other hand, the input sheet 1 is placed close to the circumferential surface of this rotating drum.
A light receiver 11 for optically reading an image, etc. is provided, and this light receiver 11 moves back and forth in the direction of arrow H2. Therefore, the entire surface of the input sheet 1 is scanned by the rotation of the rotating drum 10 (Ii vertical scanning) and the horizontal scanning (Ii) of the movement of the photoreceiver 11. The time-series signal read by the light receiver 11 is converted into predetermined data and input to the computer.The light receiver 11 and the signal processing section 12 constitute the reading means 2.

Next, the configuration of each part will be explained in more detail with reference to FIGS. 3 and 4. FIG. 3 shows a partially enlarged view of the input sheet 1, and FIG. 4 shows a block circuit diagram of the reading means 2.

For example, the input sheet 1 is printed on the surface of the white paper 30.
A plurality of lot lines 32 dividing the address area 31 in a J box shape
An address consisting of 3+j? ;0 with running display A;
The division lines 32 are formed by combining X-rays 32x in the X direction and Y-lines 32y in the Y direction in a grid pattern, and the X-rays 32
Make the line width of X thicker than Y line 32y so that it can be distinguished (for example, Y line is 0.1M-, X line is o, 5*1) o
Additionally, the outermost frame line 32w of the X-rays 32X and Y-lines 32y is made wider than the inner X-rays 32X and Y-lines 32y so that it can be distinguished. Note that the division lines 32 and 32 are displayed in black. By the way, lot line 32
(at) IJ square-shaped address area 31
. . . correspond to address numbers sequentially from the starting corner, and one address area corresponds to one address. Each address corresponds to the address of an internal memory IJ (RAM, etc.) built into the computer, and as will be described later, the image information in the address area 31. of the input sheet 1 is sequentially stored in the internal memory area.

On the other hand, within this address designation display A1 is the above-mentioned partition line 32.
2 is displayed on an image display drawn in red using a display means having a property different from that of (black), and using 19 different colors. This image display A2 can draw an image including various input elements such as characters, symbols, codes, numbers, figures, and graphs.

On the other hand, the reading means 2 is constructed as shown in FIG. In the figure, 40 and 41 are photodiodes (light receiving elements) that face the input sheet 1 and read the displayed contents, and each photodiode 40 and 41 has a color filter 42 with different spectral characteristics.
．． 43 is attached to constitute the light receiver 11. Note that the light receiver 11 may be a light receiving element having a function of a combination of a photodiode and a color filter, for example, having different light receiving characteristics for color wavelengths. The signal processing unit 12 connected to the photoreceiver 11 first connects DC amplifiers 44 and 45 each having a built-in inverter to the outputs of the photodiodes 40 and 41, respectively. By selecting the color filters 42 and 43, a signal level of approximately "1" (high level) is output to the DC amplifier 44 when the photodiode 40 reads black and red on the input sheet 1, and a signal level of approximately "1" (high level) is output when the color is white. "0"
(low level) is output. Furthermore, when the photodiode 41 reads black on the input sheet 1, the DC amplifier 45 outputs a signal level "1j (high level)", and when the color other than black (white, red) is output, the signal level "0" (low level) is output. ) outputs 〇 On the other hand, 46 is an arithmetic unit that arithmetic processes the input signal to this and generates image data to be sent to the computer side, and includes various arithmetic functions, a temporary storage device, etc. The output side of the DC amplifier 45 is connected to the arithmetic unit 46 to input the black signal, and the output side of the DC amplifier 44 is connected to the input side of the comparator 470, and the DC signal is input to the input side of the comparator 47. By connecting the output side of the amplifier 45, the comparator 47 compares both inputs and obtains the following truth 1.
Output according to the direct table.

(Truth Table) In other words, a red signal is extracted from the output of the comparator 47, and is input to the calculation unit 46 connected to the output side of the comparator 47.

The calculation unit 46 uses, for example, a microcomputer,
Various calculation functions can be provided according to a predetermined program (software). In this way, the reading means 2 reads the address designation display on the input sheet 1 and the image display A2.
can be read simultaneously using different systems.

Next, the functions of the calculation section 46 will be specifically explained with reference to FIGS. 3 and 5. FIG. 5 is a timing chart of the read signal.

As described above, the oral drum 1o rotates at a constant speed and the light receiver 11 moves back and forth, so the light receiver 11 sequentially scans the entire surface of the input sheet 1. These scanning lines are indicated by dashed lines in FIG. 1, and the total number of scanning lines is arbitrarily selected, and the address areas 31-
N scanning lines are placed in an arbitrary address area (one pixel). In the embodiment, a case where N=7 is selected will be exemplified.

Now, in Fig. 3, the scanning is La, Lb, Lc,
Assume a state in which Ld, LeLf, and Lq are performed in this order. In this case, the reading signal La of the address designation display A1 displayed in black becomes the X signal in Fig. 5, and Lb-L'q
becomes the Y signal in the figure. Therefore, in the calculation unit 46, the Y signal and the .

On the other hand, the read signals of the image display A2 displayed in red are shown as a to q in FIG. 5, respectively, corresponding to the scanning lines La to Lq.
Such signals are also sequentially supplied to the calculation section 46. Arithmetic unit 46
In this case, use a temporary memory circuit, etc.! The signal >a-cr is temporarily stored, and the presence or absence of an image in an arbitrary address area 31 is determined.

This determination method is based on an arbitrary address area 31 of the seven scanning lines.
Determined by the probability of reading a red light. In other words, if the number of scanning lines that read an image in a given address area is α, and the number of scanned lines that are not read is β, then if □≧k, it is determined as [1] α+β, where k is a constant, for example 0. It can be set to about 45 to 055. Therefore, when focusing on the address area 31a in FIG. 3, for example, the read signal is shown in the A signal section Δ31a in FIG. Input data "1" into the computer. Also, address area 31. When focusing on signal section b, it is indicated by signal section Δ31b, and this section Δ3
The image in 1b is determined to be “nothing” and the image data “
0" into the computer. In this case, since the address numbers corresponding to the address areas 31a, 31b, etc. have been read as described above, the image data will be sequentially stored in the respective addresses of the RAM or the like in the computer. Note that the method of reading the image within the address area 31 is to increase the resolution of the light receiver 11 and read it as an analog signal that is proportional (or inversely proportional) to the image area within the address area 31 in - times of scanning, for example. Good too.

Therefore, according to the user-powered device, the display A for address designation is different in color.
1 and an input sheet 1 having an image display A2 on a rotating drum 1
By scanning the sheet 1 with the light receiver 11, the image information can be read in chronological order and input into the computer as image data. Note that when inputting information, it can be stored in a RAM or the like and also displayed on a display, and corrections can be made as necessary.

In addition, in the embodiment, the address designation display A1 and the image display A2 are displayed in different colors so that they can be identified, but other than that,
One of the two displays can be drawn by applying magnetic paint, for example, and the line width of the two displays may be different, or the shading of the display may be different. optically, which can be read by
It may also be configured to include magnetic reading means.

In this manner, the computer input device according to the present invention can reliably input images to the computer with simple operations.

Moreover, since the information is read and inputted automatically, it can be done in a short time with little effort, and the image quality does not deteriorate in any way.

However, since the document reading means in existing devices such as automatic plate making machines can be used as is, the present invention can be used as a device that is easier to handle and cheaper.
