Image processing method for superimposing high-resolution character data on low-resolution image data

摘要

A primary correction unit corrects the high resolution multi-value composite data by using a logic filter table that employs the high resolution binary data stored in a memory. A secondary correction unit assigns to the blank pixels in the corrected composite data, one of a value of a pixel adjacent to the blank pixel and a blank value. An independent claim is also included for image processing method.
