Abstract

PURPOSE:To avoid waste of storage of image information by storing only a printable part with magnification among read image information. CONSTITUTION:The image read section 1 and a main body section 3 are connected by a connection wire 9 electrically. A main body section 3 has a control section 10, a RAM 11 and a print section 12, and the control section 10 is provided with a central processing unit CPU 13, a ROM 14 and a switch group 15. The CPU 13 applies print of the image by a longitudinal printable width having upper/lower interval based on the center of the magnified image information and the center of the read image information is magnified by, e.g., twice.

Description

[Detailed Description of the Invention] Technical Field> The present invention relates to an image processing device having a function of reading images such as characters, figures, pictures, etc. on paper and enlarging and printing the read image information. This relates to a device in which only the printable part is printed.

<Prior art> There are devices that have a function of enlarging and printing image information read by an image input device. For example, if the image information is enlarged twice and the reading width is the same as normal, R A M that stores image information by
The required amount is doubled, which is inconvenient (this is necessary for making other various image processing routines common).

<Object of the Invention> The present invention provides an image input processing device having a function of reading an image and enlarging and printing the read image information. It is an object of the present invention to provide an image processing device equipped with a means for enlarging image information by a printable width based on the center of the enlarged image information in response to the output of the means.

<Example> Hereinafter, the configuration of the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of an image input processing device according to an embodiment of the present invention.

In the figure, 1 is an image reading unit that reads images (characters, diagrams, pictures, etc.) on a paper surface (reading paper) 2, and 3 is a main unit that embeds the image read by the image reading unit 1. . The image reading section 1 and main body section 3 are formed in separate cases.

The image reading unit I includes a light emitting element 4 that irradiates light onto the paper surface 2, and a light receiving element 5 that receives the reflected light.
It further includes a rotating body 6 that rotates in contact with the paper surface 2, a disc (with a hole) 7 for detecting the rotation of the rotating body 6, and a photo interrupter 8. .

Further, the image reading section 1 and the main body section 3 are connected by a connecting wire 9.
It is electrically connected.

The main body part 3, the control part 10, and the random access memo I
It has a JRAM 11 and a printing section 12, and the control section 1
0 is equipped with a central processing unit CPU I 3, a read-only memory ROM+4, and a switch group 15.

Each switch +5a to +15g of the switch group 15 has the following functions.

+5a...Turn on the power to the entire device using the power switch.

Turn off.

15b... Use the 2x enlargement switch to
Turns on and off the mode that outputs double the size.

+5c: Use the graphic switch to switch between graphic mode and word mode.

+5d...Repeat switch prints the previously output image again.

+5e: The clear switch erases the image information currently stored in RAMI+.

15f... Image input switch, main switch +5
While f is being pressed and the rotating body 6 (disc 7) is moving, an image is input.

15g: Use the layout switch to turn the layout mode on and off.

Note that each of the switch groups 15 does not need to be provided in the main body section 3, and some of them may be provided in the image reading section IK. Further, the image reading section (2) and the main body section 3 may be integrally formed.

Here, the operation of this device will be explained.

In the normal operation mode, the power switch 15a is turned on,
The 2x magnification switch +5b is OFF.

The graphic switch +5c is OFF, and the layout switch 15g is OFF.

At this time, with the image input switch 15f turned on, the image reading section l is moved on the paper 2 to start inputting an image, and at this time, the photointerrupter is rotated by the rotation of the disk 7. An intermittent signal is generated at 8, which is detected by the CPU I3.

Then, the light emitting element 4 lights up, and the light receiving element 5 determines the brightness of the light reflected on the paper 2, thereby obtaining image information. The obtained image information is
It is once input to the RAM 11 through the PU13. To input image information, set the image input switch +5f to OFF.
The process ends when it becomes FF or when the RAMI+ becomes full. End of input: (Accordingly, by setting the switch group 15, the CPU I 3 inputs the R
The image stored in AM11 is processed.

Details of the processing will be described later. After processing, the image information is output to the printing section 12 and printed on paper (not shown).

The aforementioned processing procedure is shown in the flowchart of FIG.

Here, as Figure 3 of the entire manuscript, an image r on the manuscript
A case where ABCDEJ is enlarged twice will be explained.

The lines around the image in FIG. 3 indicate the reading start position and reading width.

The image in Fig. 3 is read as shown in Fig. 4. In Fig. 4, the reading height (vertical axis X) is 1.5 m, the dot density is INR/dot, and the reading length (horizontal axis Y) is 6 m.
It is crn. The numbers on each axis are expressed in units of 1.

Vertical l! The cumulative number of black dots (X) in each row of 1 to 15 meters of 111X is as shown in FIG.

FIG. 6 shows an image reading subroutine.

In the subroutine of FIG. 6, enlargement processing is executed during each type of processing in step S2.

FIG. 7 shows the processing contents of step S2.

FIG. 8 shows a printing flowchart. In the flow chart of FIG. 7, the cumulative black dot total (X) of FIG. 5 is determined and stored in step S3.

The enlargement preparation subroutine of step S2 is shown in FIG.
The expanded judgment/execution sub of the S2 step is shown. In FIGS. 9 to 11, XM represents the reading height 15), and YM represents the reading length 60).

In addition, in Fig. 11, (X, Y) is the coordinate (X, Y
) shows the image content.

If the standard value is 3, as is clear from Figure 5, A-4
(line), B=+2 (line). Then, it is checked whether it is doubled and falls within RAλI, that is, whether A - B is larger than 1/2 of the printing height.

And C=CB-A)X2=(+2-4)X2= 16>15
Therefore, it can be seen that after being enlarged twice, it becomes higher than the print height.

Therefore, printing is performed by a vertical printing width that is the same distance above and below with respect to the center of the enlarged image information.

That is, the enlargement range is expanded from the top to the area of printing @ (reading width) I/4 to 3/4.

Regarding the enlargement process, as shown in Figure 11 (C), move the part of the image information to be enlarged to the lower part of the RAM that contains the data, and then enlarge it sequentially from the top. Now, the center of the read image information has been enlarged to twice the size.

Effects> As described above, according to the image input processing device according to the present invention, only the printable portion of the read image information is enlarged and stored, so that the image information is stored efficiently and effectively. It is.
