摘要： PROBLEM TO BE SOLVED: To realize high quality of a formed image by decreasing density fluctuation caused by a variation of recording elements, deterioration of graininess caused by a shift of paper forwarding and density fluctuation for a long period when multi-path printing is performed.
SOLUTION: When the multi-path printing by a recording head equipped with a plurality of nozzles is performed, a recording data setting part 105 enables the amount of recording on every nozzle to be set from an LUT 106 for setting recording data on every main scanning of the recording head. This LUT 106 for setting the recording data keeps information on the number of paths and the number of the nozzles arbitrarily set reflected. To the amount of recording set like this, a dot pattern to be an object for forming by applying a binary processing is prepared in a half-tone processing part 108.

摘要： PROBLEM TO BE SOLVED: To suppress a deterioration in granularity depending on a low-frequency component of an image by performing N-arization processing by each scanning on the basis of restriction information determined from an N-arization result in the previous scanning, thereby forming a high-quality image. SOLUTION: When printing in a plurality of passes by a recording head having a plurality of nozzles is carried out, a scanning duty setting section 105 computes a scanning duty of each nozzle according to input image data by each scanning of the recording head. A halftone processing section 108 forms a dot pattern to be a forming object by applying N-arization to the computed scanning duty on the basis of predetermined restriction information. A restriction information computing section 111 forms the restriction information to be referenced by the halftone processing section 108 in the next scanning on the basis of the computed scanning duty and the dot pattern. At that time, the forming is carried out such that the phase of the already recorded dot pattern is opposite to that of the next formed dot pattern in the low-frequency band.

摘要： PROBLEM TO BE SOLVED: To solve such a problem that, although a memory capacity of mask data used when printing an image while dividing it into passes of multiple times has been desired to be reduced heretofore, compression depends on the mask pattern of each pass in the case that the mask for each pass is only compressed by a predetermined compressing method, so that the memory capacity cannot necessarily be reduced efficiently.SOLUTION: The record mask encoding method which encodes the mask data for recording a predetermined region of image data in N-steps includes an acquisition step for acquiring the mask data, and a formation step for forming index data in which a recording pattern of each pixel is expressed with the code data using the code data of the number of bits smaller than N assigned to the record pattern showing whether the pixel is recorded by what time scanning of the acquired mask data.
