Abstract

PURPOSE:To easily recognize characters from which sizes are different by providing a density converting part which converts the size of an image information character into a specified size. CONSTITUTION:Image information, from the information inputted from an input interface 10 in an attribute information decision part 20, is made to be expanded to an original length in an image information expanding part 30 according to the contents of the attribute information which shows the compressing system of the image information and the expanded image information is transferred to a density conversion part 40. According to the contents of the attribute information, which shows the part which should be converted into a character code, decided in an attribute information decision part 20 the conversion of density that the size of the part is converted into the reference size is executed in the part 40. The image information converted in the density conversion part 40 is transferred to an image information recognition part 50 to which the character code is recognized by referring the character pattern stored in a storage part 60. Thus, the image information characters from which sizes are different can be easily recognized.

[Detailed Description of the Invention] [Industrial Application Field] The present invention is applicable to image information input from the scanner section of an optical character reading device, or to storage in a remote terminal device such as a facsimile machine, or a magnetic disk device, an optical disk device, etc. Regarding an image information character recognition control device for inputting character information from a device as image information and recognizing this as character code information, in particular, density conversion is performed on image information characters of different sizes to obtain a constant size. The present invention relates to an image information character recognition control device having a density conversion unit that recognizes the character code after converting it into a character.

[Conventional technology]

Information about characters is input as graphic information (image information 1) from the scanner section of an optical character reading device, a remote terminal device such as a facsimile machine, or a storage device such as a magnetic disk device or optical disk device, and this is converted into a character code. The recognition control bag W (hereinafter referred to as an image information character recognition control device or simply a recognition control device) is a scanner unit for reading image information and a recognition control bag W for recognizing the read image information as a character code. It is integrated with the recognition section. Therefore, the recognition unit recognizes only the image information input from the scanner unit, and the recognition means for recognizing the character code of the image information uses a certain size stored in the storage unit of the device. [Problem to be Solved by the Invention] As described above, the conventional image information character recognition control device uses the image information character recognition control device to Since characters are recognized by referring to a character pattern of a certain size,
Characters written in sizes other than those stored in the memory cannot be recognized, and in order to be able to recognize character patterns of various sizes, character patterns of all sizes must be stored in the memory. Since the image information character must be stored in Therefore, it is an object of the present invention to provide a recognition control device that can easily recognize image information characters of different sizes.

[Means for solving problems]

The image information character recognition control device of the present invention includes an input interface for inputting character image information compressed according to a predetermined compression method and its attribute information from a host device, and an input interface for inputting the image information and the attribute information from the input interface. is input, these are separated, and the compression method information indicating the compression method in the attribute information and the density conversion information indicating the character size necessary for density conversion and the character position to be converted are determined and sent. an attribute information determining section that sends out image information; and decompressed image information obtained by inputting the image information and the compression method information from the attribute information determining section and converting the image information to the original length according to the compression method information. an image information decompression unit that outputs; a density conversion unit that receives the decompressed image information and the density conversion information and outputs the decompressed image information at a specified character position as density-converted image information having a predetermined size; an image recognition unit that inputs density conversion image information, compares it with character patterns stored in a storage unit, recognizes a character code, and sends out character code information; and an image recognition unit that inputs the character code information and sends out character code information; and an output interface for transferring a reference character pattern of a certain size to the storage section.

The information buses 80 are connected to each other by an information bus 80. The image information recognition section 50 and the storage section 60 are also connected by an information bus 80.

Furthermore, the image information decompression unit 30 and the density conversion unit 40 are as follows:
It is connected via a control bus 81 for inputting control information from the attribute information control section 20.

The image information of the information inputted to the attribute information determining section 20 from the input interface 10 connected to the upper circuit is converted to its original length by the image information decompressing section 30 according to the content of the attribute information indicating the compression method of the image information. The expanded image information is transferred to the density conversion unit 40, where the size of the area is determined according to the content of the attribute information indicating the area to be converted into the character code determined by the attribute information determination unit 20. A density conversion is performed using the reference size as the reference size.

The image information converted in the density conversion unit 40 is transferred to the image information recognition unit 50, where the character code is recognized by referring to the character pattern stored in the storage unit 60, and the result is character code information. The signal is output from the output interface 70 to the lower circuit. The attribute information inputted together with the image information to the attribute information determining unit 20 is processed by the attribute information determining unit 20, which determines the compression method of the image information, the part of the image information that needs to be converted into character code information, and the character code required for density conversion. The size of the data is determined and transferred to the image information expansion section 30 and the density conversion section 40 via the control bus 81.
