Abstract

PURPOSE:To output picture information from a storage section at picture reproduction inversely at reading, and to obtain the same reproduced picture as an original picture, through the pickup and storage of minimum range of information only required at reproduction output for the picture information obtained from a reading section. CONSTITUTION:Characters and graphs on an original 1 are optically read at a reading section 2, the change in density of row and column picture elements is changed into a binary signal and applied to a control section 3. This control section 3 receives the picture elements at each row, the picture element data of row and column are monitored while being stored on a memory for one page's share to store the row in which the detected signal of the picture element data first appears and the positions of beginning and end of the column in the row. The position of a column where the detected signal of the picture element data at each row first appears and that finally appears are stored while revising the minimum and maximum values through the comparison with the preceding row. The picture data for one page's share is picked up at the control section, address information of the effective area is added and given to a storage section 4, and the picture information from the storage section 4 is reproduced with the inversed operation as the reading at the control section 3 and a reproducing section 5.

Description

DETAILED DESCRIPTION OF THE INVENTION An object of the present invention is to provide a method for storing a document image that has not been input into an image processing device with the minimum amount of information necessary for image reproduction, and for reproducing it at the same position as the document image. Our goal is to provide the following.

Ti! When storing image information, it is very important to minimize the storage capacity. The conventional technology compresses and stores the yomizutou # in terms of run length, etc., and decompresses and outputs the compressed data during playback. The present invention takes note of the fact that the prior art stores information that is not included during reproduction, such as the margins of a document, and provides a method for storing such information by discarding this portion.

This method monitors the read information when reading the original image with the reading unit, and stores the start and end points of valid information.
After the reading is completed, effective information is cut out from the information in the original page, and position information of the information area (relative address information for the JJill page) is created, and the information is awkwardly added and transferred to the storage unit. During playback output, the output section analyzes the position information and image information passed from the storage section, in reverse of the reading described above.
By outputting the image information according to the position information, it is possible to obtain the original image and the reproduced image.

An embodiment of the present invention will be described below with reference to the drawings.

Figure #11 is a block diagram of an image processing device according to the present invention. In the figure, 1 is the original, 2 is the original expansion part, 3 is the control part,
4 is a storage section, 5 is a reproduction section, and 6 is a copy output paper.

In the first step, images such as characters and figures on the document are read by the reading section 2. The reading unit 2 is a scanning type optical reader that reads the original 1, converts individual density changes of pixels in rows and columns into binary symbols, and sends the converted signals to a control unit.

The control section 3 receives the pixel data for each row sent from the reading section 2, monitors the pixel data of the rows and columns while lying on a part of the memory, and detects the pixel data when the detection signal of the pixel data appears first. Stores the starting and ending positions of the row and columns within that row. After this memorization is carried out, from the next row, the position of the column where the first detection signal appears and the position of the last column where the detection signal appears among the one thread data for each row are compared with the previous row. Recultivate and memorize the greatest value with the male and female immortals.

At the same time, in order to detect the last line where the detection bar code is present in the pixel data of the row, pixel data continues to be received while updating the memory of the row position.

In this way, after receiving the pixel data for one part of the original,
Displays the range of valid data for data in memory
! ! The position information of the first row of fists, the row after I#, the small column of carp, and the largest column are completed in each storage regime.

Based on this position information, the control section 3 extracts the image data of the #lJ range necessary for storage from a part of the memory, adds address information of the effective area, and sends it to the storage section 4.

The storage unit 4 stores the image data sent from the control unit 3 in a form that can be retrieved during playback.

At the time of image reproduction, the control unit 6 reads the address information from the dl11 data sent from the storage unit 4, contrary to the reading operation described above.
Then, the pixel data is developed into one page worth of pixel data and sent to the reproduction section 5. The reproduction section 5 outputs the pixel data onto copy paper 6.

FIG. 2 is a block diagram for obtaining position information of valid data. Pixel data of rows and columns are input to data input circuit 1o.
The data is stored in the page memory 11 through the process. At this time, the pixel data is simultaneously sent to the row storage circuit 14 and the column storage circuit 15. The row storage circuit 14 is composed of an address register that can store both addresses of the start row and end row of valid data, and a detector for combining and detecting the presence of valid pixel data in the data. Inspect...
Then, the row address at that time is obtained from the X address circuit 12 and set in both the start row and end row address registers.

After an address is set in both registers, each time valid pixel data is detected from the next row data, only the end row address register is updated to the address of that row.

The column storage circuit 15 includes an address register that can store both addresses of the start column and end column of the data, a detector that outputs whether valid pixel data exists in the row data, and a start column of the detected column address. , consists of a magnitude comparator for the end column and both address register registers, and when valid pixel data is detected in the row data, the column address at that time is obtained from the X address register circuit 13 and is applied to both the start column and the end column. The contents of the register are compared in size, and when the start address is smaller than the register value and the end address is larger than the register value, the value of the X address circuit 13 corresponding to the contents of the register is changed to ITi. When the operation is repeated until the end of the input data, as shown in FIG. on the page (a
The positional information of 1, 1, 2, 1, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 23 and 28, 1, 2, 2, 3, 3, 4, 50 column storage circuit 14 column storage circuit 150 and column storage circuit 150, respectively, are stored. The extraction address selection circuit M1-7 is connected to the selection circuit 17.The extraction address selection circuit M1-7 is composed of two address registers for storing the start and end addresses of the valid area. From the start, start, end, and end address registers of the column storage circuit 15, the start address (5) and end address (average) of one effective area shown in FIG. 6 are obtained.

The image data to be sent to the storage unit 4 has a start address (5) and an end address (B) as shown in FIG.
is added.

According to this embodiment, when processing image information, data such as margins can be deleted before being transferred and stored, which is effective in improving processing speed and reducing storage capacity.

According to the present invention, only the information in the minimum area necessary for reproduction output can be transferred and stored when reading worn characters, figures, etc. There is a small effect.
