IPC: G06T5/00
Filed: 1989-06-09
Abstract: PURPOSE:To generate a picture giving natural impression by varying the weight of a binarization error in response to a picture element. CONSTITUTION:An error filter processes a picture element corresponding to a processing object picture element and preceding and succeeding picture elements to the object picture element in one preceding picture element of the processing object picture element and in one preceding scanning line of the scanning line. Then the error filter gives weights W1-W4 to binarizing errors l1-l4 of a picture element. The weights W1-W4 are not constant but vary with a processing object picture element of an original picture and each weight is expressed as a function of the picture element. Thus, the characteristic is reproduced with fidelity as to the entire picture by decreasing the weight W1 smaller as to a character area and increasing the weight W1 as to a graph area. Moreover, the weight is decided based on the picture element as to each picture element and each area is linked smoothly with a change in the unit of one picture element.
