Embodiment Construction

[0025] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0026] (first embodiment)

[0027] Fig. 1 is a block diagram showing the functional configuration of an image processing apparatus according to the present invention.

[0028] Referring to Fig. 1, numeral 2 denotes a scanner for inputting an original image. NOTE: This original image does not always have to be input by scanner 2. For example, images captured by a digital camera, images stored in a storage device, can be imported. Numeral 4 denotes a FlashPix rasterizer (rasterizer) for converting an image input from the scanner 2 into a FlashPix image as a file format of the image. Numeral 6 denotes an image memory for storing the FlashPix image converted by the FlashPix rasterizer 4 .

[0029] Numeral 8 denotes an optimum character recognition resolution determination circuit for determining the optimum resolution for character recognitio...

Abstract

An input image is converted into an image in a predetermined format. An optimal character recognition resolution determination unit determines, using the converted image, an optimal resolution to be used upon executing character recognition of the input image. A character recognition circuit executes character recognition of the input image on the basis of the determination result. An output circuit outputs the recognition result.

Description

technical field [0001] The present invention relates to an image processing device and method, and a computer-readable memory. Background technique [0002] Conventional image processing equipment with character recognition basically recognizes a binary image at a given resolution. On the other hand, character recognition accuracy is closely related to the resolution of the input image. [0003] However, because conventional image processing devices can only recognize images of a given resolution, character recognition is not always done under the most ideal conditions in terms of recognition accuracy. Contents of the invention [0004] In view of the above problems, an object of the present invention is to provide an image processing apparatus and method capable of improving character recognition accuracy, and a computer readable memory. [0005] According to one aspect of the present invention, an image processing device is provided, comprising: [0006] input means f...
