Abstract
This invention is directed to an image processing apparatus and method capable of analyzing a character image to detect a blur, and reducing the blur on a printed product. According to the method, a scanner reads an original character image, generating image data. A blur and deterioration of a character image represented by the image data are detected. Portions corresponding to the detected blur or the deterioration are removed from the image data. The image data from which the portions corresponding to the blur or the deterioration are removed is output to an image output unit.
Claims7
An image processing method of processing image data generated by reading an original character image by a scanner, the method comprising:
- a detection step of detecting a blur and deterioration of a character image represented by the image data;
- a removal step of removing, from the image data, portions corresponding to the blur or the deterioration detected in the detection step;
- and
- an output step of outputting, to an image output unit, the image data from which the portions corresponding to the blur or the deterioration are removed in the removal step.
An image processing system comprising:
- a scanner which reads an original character image to generate image data;
- a computer which receives the image data generated by said scanner, detects a blur and deterioration of a character image represented by the image data, removes portions corresponding to the detected blur or the deterioration from the image data, and outputs the image data from which the portions corresponding to the blur or the deterioration are removed;
- and
- a printer which prints an image based on the image data output from said computer on a printing medium.
An image processing apparatus comprising:
- a scanner unit configured to read an original character image to generate image data;
- a detection unit configured to detect a blur and deterioration of a character image represented by the image data generated by said scanner unit;
- a removal unit configured to remove, from the image data, portions corresponding to the blur or the deterioration detected by said detection unit;
- an output unit configured to output the image data from which said removal unit removes the portions corresponding to the blur or the deterioration;
- and
- a printer unit configured to print an image based on the image data output from said output unit.
