Title: Error diffusing method
Inventor: YAMAZAKI NOBUHISA
IPC: H04N1/405
Filed: 1997-12-25
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of jaggy at the edge of a character by performing error diffusion processing while changing the degree of error influence corresponding to the sharpness degree of an image. SOLUTION: Maximum and minimum values are found from the density data of pixels around an object pixel to be binarized, and the sharpness degree of the image is found. The degree of error influence corresponding to that degree is calculated. Bias density data V of the object pixel are calculated by density data A of the object pixel, error data and a calculated degree αof error influence. If the V is <=255, the binarized data of the object pixel are made into '0' and a value to be stored in an error buffer is made into V. When the V is not <=255, the binarized data of the object pixel are made into '1', and the value to be stored in the error buffer is made into (V-255). When the degree α of error influence is equal with '0', the density data V become (A+V) and the error diffusion is performed to the binarized data.  In the case of α=1, the density data V become (2A) and the error diffusion is not performed.
