IPC: B41J2/52
Filed: 1998-01-16
Abstract: PROBLEM TO BE SOLVED: To make a reduction in printing width inconspicuous by detecting a target point of image signal data and gray levels of adjacent points to the target point in a main scan direction or sub scan direction, and correcting to increase the gray levels of the adjacent points when the target point has a maximum density level and the adjacent points have a minimum density level. SOLUTION: Video data sent from a personal computer or the like to a printer is stored in a VRAM 21, and then sent to an 8-bit shift register 18 from a laser scanner part sequentially in a main scan direction. A target point and data of gray levels of adjacent points to the target point in the main scan direction are read and sent to a detection correction circuit 20. Concurrently with this, data in the shift register 18 are shifted synchronously with a video clock and new video data are read. When the detection correction circuit 20 detects that the target point has a maximum density level and both adjacent points have a minimum density level, the gray level of the adjacent points is corrected to increase.
