Abstract

PURPOSE:To attain the edition by a character by reading an existing document by an image sensor, etc., separating automatically characters, numerics and marks on the read-out document into one character according to a picture element distribution. CONSTITUTION:A document input device 1 makes the document into a binarization picture at a sufficient resolution level to express the document with the group of character picture elements and fetched said picture to a memory device 2. The histogram of the number of black picture elements on each row of the inputted picture is calculated. In terms of a periphery distribu tion in a row direction, a range where the character exist exceeds a certain value, and the range where characters exist is segmented by the row. In the same manner, a periphery distribution in a column directionn is obtained to separate characters, numerics, marks, etc., into one character, and the binarization pattern of each memory and its appearing order are stored in a memory 6. At the time of edition, information stored in the memory 6 is read out to display on a display device 3, and addition, deletion, correction of the character pattern, line feed, etc., are executed by the character.

Description

DETAILED DESCRIPTION OF THE INVENTION [1] Industrial Applicability The document input/edit method of the present invention relates to an image processing technology that executes everything from document input and storage to document editing.

There are three areas of application:

The first is when data input as an image is processed and output as an image again, such as data compression for image data transmission, noise removal, and blurred image improvement. The second is when the result of performing certain calculations on the input data is output as an image, such as an X-ray tomographic image,
These include the configuration of an ultrasound tomographic image. The third type analyzes image data and attempts to recognize what the object is, such as pattern recognition and image understanding, which extremely compress the amount of information between input and output.

(2) Purpose of the Invention There is a word processor as a document input/editing device, but with this it is necessary to input all the characters in advance using a keyboard etc., and although editing after input is easy, it takes time to input. In addition, although optical character reading devices are easy to input, there are restrictions on the size, font, type, etc. of characters that can be read.The present invention reads existing documents with an image sensor, etc. , numbers, symbols, etc. are automatically separated into character units, and the purpose is to enable editing of each character.

[3] Structure and operation of the invention In FIG. 1 showing the structure of the present invention, the document input device shown in (1) generates a binary image (2) with sufficient resolution to express a character as a collection of pixels. Import to storage device. Here, the character pattern is expressed as a collection of white and black pixels as shown in FIG.

Next, a histogram of the number of black pixels in each row of the input image is calculated. (This is called the marginal distribution in the row direction.) For example,
As shown in FIG. 4, in the peripheral distribution in the row direction, the range in which characters exist exceeds a certain value. Therefore, the position where a character exists in the line direction can be detected. Next, cut out the range where characters exist for each row, and calculate the marginal distribution in the column direction for each row by
Obtain as shown in the figure. As a result, for example, the range in which characters exist can be determined for each line. In this way,
Separate letters, numbers, symbols, etc. in a document into individual characters, and store the binary pattern of each character and its order of appearance in the memory shown in Figure 1 (
6). These processes are performed by the data processing device (4) shown in FIG. Next, when editing the input document, read out the information stored in the memory (6) in Figure 1 and display it on the display device (3), add characters,
Perform deletion, correction of character pattern, line break, etc. The edited document is output by a printing device (5). The flow of the above processing is summarized in FIG.

[4] Effects When editing an existing document character by character, there is no need to re-enter data using a keyboard, etc., as in a word processor. On the other hand, optical character reading devices are easy to input, but there are restrictions on the size, font, type, etc. of characters that can be read.
This method automatically separates characters with simple input and stores them as character patterns, allowing editing on a character-by-character basis. Furthermore, since characters can be extracted by simple calculations, it can be easily integrated into an LSI, and the device can be made smaller and cheaper.
