Abstract

PURPOSE:To input an erected picture independently of a picture read direction by expanding picture information read from a reader in a direction corresponding to the direction designated by the designating means. CONSTITUTION:For example, when a key 42 relating vertical read is depressed to read a picture in a vertical direction, a one line picture data outputted from a handy scanner 17 is stored once in a buffer 91 and the content of the buffer 91 is expanded sequentially from the picture storage area 92. On the other hand, when the key 43 is depressed to read a picture in a horizontal direction, the data stored in the buffer 91 is subjected to crisscrossing conversion and expanded into the vertical position of the picture storage area corresponding to the value represented by a processing line number 93. Thus, an optional read direction is set.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an image processing system, and more particularly to an image processing system that optically inputs and processes a document image.

[Prior Art] A handy scanner is a typical example of a conventional image reading device.

Usually, this handy scanner is provided with a roller and a circuit (for example, an optical or magnetic encoder) that generates a pulse signal as the roller rotates. This pulse signal is used for the timing of processing related to image reading and the like.

The operator moves this handy scanner in a predetermined direction with respect to the document surface to read an image, and transfers the data to the main body of the apparatus for image processing.

[Problems to be Solved by the Invention] Incidentally, the image input direction by the above-mentioned general handy scanner is limited to one direction, for example, from the top to the bottom of the document.

Therefore, for example, if a document is read from the bottom to the top, an upside-down image will be input. However, a problem occurs when the pages of a relatively thick book are to be read. This is because the paper surface near the binding margin of the two-page spread will be curved, and even if you try to read the image by moving the handy scanner in a direction parallel to the binding margin, the curved paper surface and the reading surface of the handy scanner will overlap. This is because a gap will occur between them. Therefore, it can be said that it is almost impossible to read a good image in such a case.

Therefore, if the device that inputs the image from the handy scanner has an editing function such as rotation, the handy scanner can be read perpendicular to the binding margin to input the flipped image, and in the subsequent editing process, the image will be It is possible to rotate the .

However, in this case, troublesome operations must be performed many times until an erect image is obtained, which increases the burden on the operator.

The present invention has been made in view of such prior art, and it is an object of the present invention to provide an image processing system that can set an arbitrary reading direction and obtain an erect image based on the set direction. be.

[Means for Solving the Problem] In order to solve this problem, the present invention includes the configuration shown below.

That is, in an image processing system that includes a reading device that manually reads an image of a document and a device that processes the read image, there is provided a designating means for specifying the reading direction of the document with respect to the document by the reading device, and a device that stores and holds image information. memory retention means;
and a developing means for developing the image information read from the reading device into the memory holding means in a direction corresponding to the direction specified by the specifying means.

[Function] In this configuration of the present invention, when the read image is developed in the memory storage means by the development means, it is developed based on the set direction.

[Embodiments] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In the figure, 1 and 2 are buses that connect various peripheral devices shown below. 3 is a central processing unit (CPU),

Reference numeral 6 represents a keyboard for inputting operator instructions (including a reading direction designation key to be described later) and various data, and 7 represents a mouse for selecting or specifying various menus. 9 is a CRT for displaying various information; memory 4;
The image data etc. in the image storage area 92 in the CRTC (C
RT controller) 8. 11 is a magneto-optical disk device (MOD), and input/output is controlled by MODC 10. Further, 13 is a floppy disk device, and 14 is a hard disk device, each of which has an HF
Data is input and output via the DC 12. 16 is a printer, 17 is a handy scanner 17, and output (printing) to the printer 16 and image input from the handy scanner 17 are performed via the 5PC 15.

The appearance of the handy scanner 17 is as shown in FIG. 2, and by moving it while the button 21 is pressed down, an image of one line with the width of the marks 17a and 17b can be scanned into 5 pages.
It is input via C15. Also, regarding the reading and output timing of this L-line image, the handy scanner 17 has an encoder (optical type and magnetic type, but either type is fine) that rotates as it moves. Reading and output are performed in synchronization with pulse signals generated from the detection elements of this encoder. Therefore, a certain amount of time is required from reading to output, and if the handy scanner 17 is moved faster than the time required, normal reading will not be possible. Therefore, in addition to the one line of data read from the handy scanner 17,
It outputs reading status information (information on whether reading is in progress or whether reading output of one line has been completed normally) and the pulse signal shown above. These state information (status) and pulse signals are latched in the 5PC 15 as a status 81 and the number of read lines 82, as shown in FIG. The latter has 82 lines to read using a handy scanner of 17.
This is a count value obtained by counting the pulse signals output from the above, and the number of lines that have already been read is stored.

Explanation of Principle (FIGS. 3 to 9)> The principle of image reading processing in the image processing apparatus of this embodiment described above will be explained below.

FIG. 3 shows an example of how the handy scanner 17 operates when reading a document in the vertical direction.

Note that 31 in the figure is a document, and the handy scanner 17 moves in the direction of the arrow shown in the figure to read it. Therefore, since the image is read with the width of the marks 17a and 17b shown above, the image in the area indicated by 32 in the figure is read.

Further, FIG. 4 shows an example of the operation of the handy scanner 17 when reading a document in the horizontal direction.

In the embodiment, an erect image as shown in FIG. 5 is obtained regardless of whether the image is read vertically or horizontally with respect to the document.

To achieve this, in the embodiment, when reading a document image with the handy scanner 17, it is first specified whether the reading direction is vertical or horizontal with respect to the document. The keyboard 6 is provided with keys 42 and 43 for designating the reading direction (see FIG. 5), and the reading direction is determined by pressing these keys. That is, by pressing the key 42, vertical reading is specified, and by pressing the key 42, horizontal reading is specified. Further, when these keys 42 and 43 are pressed, a light emitting diode is provided inside to notify the operator that the key has been selected.

Here, for example, press the key 42 related to vertical reading and press the third
FIG. 6 shows the display state of the CRT 9 while the document 31 is being read by the operations shown in the figure. Vertical reading is achieved by temporarily storing one line of image data output from the handy scanner 17 in the buffer 91, and sequentially developing the contents of the buffer 91 from the top of the image storage area 92. At this time, the line position to be expanded next is stored in the number of lines to be processed 93, and the expansion process is performed according to this information, and the contents of the number of lines to be processed 93 are updated every time the processing for one line is completed.

On the other hand, when the key 43 is pressed and a horizontal reading operation is being performed, the display screen state becomes as shown in FIG. 7, which is achieved by the following process. That is, as shown in FIG. 9, the data stored in the buffer 91 is vertically and horizontally converted and expanded to the vertical position of the image storage area 92 corresponding to the value indicated by the number of processing lines 93. Incidentally, when this process is completed, it goes without saying that the contents of the number of lines to be processed 93 are updated.

Description of Processing Procedure> An example of a processing procedure for realizing the above-mentioned contents is shown in FIG. 10, and its contents will be explained below.

First, if it is determined in step S1 that a key has been pressed manually, it is determined in the next step S2 whether or not the pressed key is the key 42 relating to the start of vertical reading. If it is detected that the key 42 has been pressed, the process proceeds to step 85 and subsequent steps, and vertical reading processing is executed.

In the vertical reading process, first, in step S5, the number of lines to be processed 93 is initialized to "0". Then, in the next step S6, it is determined whether the reading has been completed, that is, whether the button 21 of the handy scanner 17 is released. If it is determined that the button 21 is pressed down, the process advances to the next step S6, and the number of processing lines is 9.
It is determined whether 3 and the number of read lines 82 are equal.

This means nothing more than determining whether one new line of data has been read by the handy scanner 17. If the number of read lines 82 is greater than the number of lines to be processed 93, the process advances to step S8 and the corresponding 1 line of data has been read. After storing the data in the buffer 91, the data is transferred (displayed) to the position of the image storage area 92 indicated by the number of processing lines 93. After this processing, the number of processing lines 93 is updated in step S9, and the process returns to step S6.

On the other hand, if it is determined in step S2 that a key other than the key 42 has been pressed, the process advances to step S3, and it is determined whether the key 43 is pressed this time. At this time, if it is determined that the key 43 has been pressed, the processing from step 810 onwards is executed.

In step SIO, the number of lines to be processed 93 is set to "0", and in step S11 it is determined whether reading has ended. If it is determined that reading is continuing, step S12
Next, the number of lines to be processed is 93, and the number of lines to be read is 82.
Determine whether it is equal to or not. If these values are different, the process moves to step S13, where the input 1-line data is stored in the buffer 91, subjected to vertical/horizontal conversion, and transferred to a position within the image storage area 92 indicated by the number of lines to be processed 93.

After updating the number of processing lines to 14 in step S14, the process returns to step Sll.

In addition, if the determination in step S3 is NO1, that is, the key 42
．． If it is determined that a key other than 43 has been pressed, the process advances to step S4 to perform processing (editing processing, etc.) corresponding to the input key.

Through the above processing, it is possible to obtain an erect image even if the document is read in the vertical or horizontal direction. Therefore, if these are switched according to the condition of the object to be read, a good image can always be obtained with a simple operation.

Description of Other Embodiments> By the way, in the above-described embodiments, the vertical reading direction was determined to be from top to bottom, and the horizontal direction was determined to be from left to right.

Therefore, in the following, as shown in FIG. 11, the vertical reading direction is from bottom to top (hereinafter referred to as the reverse direction, and the direction in FIG. 3 is referred to as the forward direction) to obtain an erect image. An example will be described.

In addition, in this embodiment, instead of specifying whether to move the handy scanner 17 in the forward direction or to read in the reverse direction, the moving direction of the handy scanner 17 is detected and the erect image is automatically generated. It's something you get. Therefore, the operator can obtain a royal image regardless of whether the reading direction is forward or backward simply by specifying whether the image should be read in the vertical or horizontal direction.

Regarding the detection of the moving direction of the handy scanner 17, in the embodiment, the encoder in the handy scanner 17 has two detecting elements, and the moving direction is detected based on the phase of the pulse signal output from each detecting element. It is.

At this time, the status 81 and movement direction 83 of the handy scanner 17 are also stored in the 5PC 15 as shown in FIG.
(1 bit indicating forward or reverse direction) is assumed to be latched.

The following will be explained according to the flowchart in FIG.
The same flowchart shows that the judgment in step S2 of FIG. 10 is Y.
It shall be processed at the time of ES. That is, steps 85 to S9 may be replaced with the flowchart of FIG. 13.

Now, when the key 42 related to the start of vertical reading is pressed in step S2 of the flowchart of FIG. 10, the process moves to step S25 of FIG. 11, and processing related to vertical reading is executed.

First, in step S25, the process branches to step S26 and step 330 based on the initial moving direction of the handy scanner 17.

If it is determined that the direction is forward, first, step S2
6, and set the number of lines to be processed 93 to O''.Next, if it is determined in step S27 that reading is in progress, proceed to step S28, and set the read data of one line to correspond to the number of lines to be processed, 93. The process proceeds to step S29, where the number of lines to be processed is 9.
3 and returns to step S27. During this time, when it is detected that the button 21 of the handy scanner 17 is released, the process returns to step S1 in FIG.

On the other hand, if it is determined that the initial moving direction of the handy scanner is the opposite direction, the process proceeds to step S30. In step S30, first, the number of processing lines 93 is set to the lowest position of the image storage area. If it is determined in step S31 that reading is in progress, the process advances to step S32.
The read one line of data is transferred to the position of the image storage area 92 indicated by the number 93 of lines to be processed. Then, in step S33, one is subtracted from the number of processing lines 93, and the process returns to step S31.

Although the above explanation was about vertical reading, it goes without saying that horizontal reading can also be processed in exactly the same way.

As explained above, according to this embodiment, the original image is
An erect image will be obtained no matter which side the image is read from.

Furthermore, in the embodiment, the reading direction was detected using the output pulse phase of the two detection elements of the encoder.
It is perfectly acceptable to employ means for detecting changes in directions other than this.

[Effects of the Invention] As described above, according to the present invention, it is possible to input an erect image regardless of the image reading direction.
