記録装置、記録方法及びデータ供給方法
Document Type and Number:
Japanese Patent JP3571891
Kind Code:
B2
Abstract:
Multi-pass recording is performed to record an input image by plural scans of a recording head over a recording medium in a main scan direction with at least one interposed sub-scan. A thinned image is provided in each scan. Recording data for the input image is produced by creating mask patterns having a resolution lower than the recording resolution in the main scan direction and/or the interposed sub-scan direction on the basis of a random number array. The created mask patterns or enlarged forms of the created mask patterns are combined with input image data to produce the thinned images. A logical AND of the mask patterns and the input image data may be computed for use as recording data.
