Title: Reducing device for pseudo half tone image
Inventor: NAKAJIMA YOSHIHIDE
IPC: H04N1/405
Filed: 1986-08-13
Abstract: PURPOSE:To reduce an image without deteriorating gradation width expressed by an original image and the finess of the gradation by evenly selecting the thresholds by dithers and thinning picture elements. CONSTITUTION:An in-matrix main scan position counter 7, a main scan matrix counter 8, an in-matrix subscan position counter 9 and a subscan matrix counter 10 specify picture elements. Judging from the readings of the counters, a thinning decision circuit 11 decides which picture elements that said counters specify are thinned or not. The thinning decision circuit 11 evenly selects the thresholds of dithers corresponding to picture elements comprising the original image, and is constituted of memories that decide selected picture elements so that distances between said elements can be roughly constant. Thus a dither image can be reduced with the gradation width and the finess of the gradation unchanged.
