Title: Image-forming device and gradation characteristic adjustment method for the image-forming device
Inventor: AKITA HIROSHI
IPC: B41J2/52
Filed: 1997-07-14
Abstract: PROBLEM TO BE SOLVED: To prevent effectively the deterioration in image quality at switching of pixel density and change of a paper mode by introducing offset for a gradation curve to a gradation characteristic curve of the image-forming device that is changed at the switching and the change. SOLUTION: A test patch signal for gradation characteristic adjustment is given to a semiconductor laser 110 in the stage of forming a test patch image and a density sensor DS senses the density. Then an offset is adjusted, based on a pattern obtained in the pattern-forming stage. This adjustment offsets a gradation curve by parallel translation of the gradation curve. A desired gradation curve is obtained by applying other gradation correction such as gamma correction to the gradation curve after the offsetting, so that this results in that sharp images are maintained even after pixel density conversion. The gradation curve is offset by allowing a control section 120 to rewrite correction data for gradation correction conducted by an image-processing circuit 70.
