Patent ID: 7355744

Claim:
An image-processing device comprising: a first memory; a second memory; a controller that converts a high-resolution character data to a high-resolution binary data, stores the high-resolution binary data into the first memory, converts the high-resolution character data to a low-resolution character data, stores the low-resolution character data and a low-resolution image data as low-resolution composite data into the second memory, converts the low-resolution composite data into a high-resolution multi-value composite data, corrects the high-resolution multi-value composite data to a corrected high-resolution multi-value composite data by using a logic filter table that employs the high-resolution binary data stored in the first memory, and corrects the corrected high-resolution multi-value composite data by assigning to a blank pixel in the corrected high-resolution multi-value composite data, that was generated when correcting the high-resolution multi-value composite data, one of a value of a pixel adjacent to the blank pixel and a blank value.
