Abstract

PURPOSE:To provide a character recognition device realizing the quicking of data transmission. CONSTITUTION:The device is provided with an image reading part 1, image memory part 2, a character segmenting part 3, a space/character recognition part 4, a space code counter part 5, a transmission data memory part 6 and a modem transmission part 7. When space data is consecutive in read image data, the number is counted to store the counter value in a transmission memory instead of space data. Then, a usual character data is stored in the transmission memory as it is and the pieces of data are successively transmitted from the modem transmission part to an external terminal.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a character recognition device having a transmission function.

[0002]

2. Description of the Related Art In a conventional character recognition device having a transmission function, all recognized space codes are transmitted. However, general sentences and the like have a large number of space portions continuous as compared with the character portion, and when all the space data are transmitted, a great amount of transmission processing time is required.

A conventional character recognition device having a transmission function will be described below with reference to FIG.

The document data is read by the image reading unit 41, converted into bitmap data, stored in the image memory unit 42, and the character cutting unit 43 cuts out a character area for each character. The recognition unit 44 recognizes characters and spaces. The recognized character code is stored in the transmission data memory unit 45 and sequentially transmitted to the outside by the modem transmission unit 46.

[0005]

As described above, conventionally, all recognized space codes have been transmitted. Therefore, in the case of a sentence containing a lot of space data, the transmission time is long for the amount of character information and the transmission cost is high.

The present invention solves the above problems, and an object of the present invention is to provide a character recognition device having a high-speed data transmission function with a low transmission cost.

[0007]

In order to achieve the above object, the present invention counts the number of space codes continuously by a counter when the space code is more than a certain number and stores the count number in a transmission memory to make the number constant. In the following cases, the space code is stored as it is in the transmission memory.

[0008]

According to the present invention, since the number of space codes is transmitted instead of the space code by the above-mentioned structure, the transmission speed is improved.

1 is a block diagram of a character recognition device according to an embodiment of the present invention, FIG. 2 is a hardware block diagram of the same device, and FIGS. 3 to 5 are software flowcharts of the present invention.

In FIG. 1, 1 is an image reading unit, 2 is an image memory unit, 3 is a character cutting unit, 4 is a space / character recognition unit, 5 is a space code counter unit, and 6 is a transmission for storing recognized data and the like. The data memory unit 7 is a modem transmission unit. The relationship and operation of each component of the character recognition apparatus of this embodiment having the above components will be described with reference to the flowcharts of FIGS.

The image reading unit 1 reads image data from a document. The read data becomes binary data and is stored in the image memory unit 2. Then, character cutting is performed for each one character in the upper left corner of the image memory (the size of one character is specified in advance by a parameter or the like, and the character cutting is performed with reference to this). The cut-out image data is recognized by the recognition unit 4 character by character. If the cut out data area is space data, the data one character before is referred to. When the reference data is the same space data, the space code counter unit 5 is incremented. If the reference data is not the space data, the space code is stored in the transmission data memory unit 6. If the previously cut out data area is a normal character and the space code is being counted up, it is determined that the space code has been counted, and the numerical contents of the space code / counter unit 5 are transferred to the transmission data memory unit 6 Store in and clear the counter. Further, the recognized normal character is stored in the transmission data memory unit 6. The above operation is performed until the recognition of all areas is completed, and after completion, the contents of the transmission data memory unit 6 are transmitted to the partner terminal via the modem transmission unit 7.

As described above, according to the character recognition device of the embodiment of the present invention, the space / character recognition unit and the space code counter unit are provided, and when the space codes are continuous, the number of space codes is counted to replace the space code. Since the count number of the space code is stored in the transmission data memory unit and is transmitted, high-speed transmission is possible as compared with the conventional sequential transmission of space code.

[0013]

As is apparent from the above embodiments, according to the present invention, consecutive space characters are counted and the count value is transmitted instead of the space data, so that the transmission speed can be increased and efficiency can be improved. A recognition device can be provided.
