Patent number: 11948026Abstract: Formed is a dither pattern that makes it possible to output an image with excellent dot dispersibility and reduced graininess regardless of controls after quantization processing. To this end, an extended pattern in which multiple divided pixels correspond to each of multiple pixels included in quantization data and one or more of the multiple divided pixels are determined as dot-arrangeable-pixels in which dots can be printed is generated. Thereafter, the thresholds of the dither pattern are set based on the extended pattern in which the dots are arranged to obtain predetermined dispersibility.Type: GrantFiled: April 26, 2022Date of Patent: April 2, 2024Assignee: CANON KABUSHIKI KAISHAInventors: Junichi Nakagawa, Hirokazu Tanaka, Tsukasa Doi, Mayuko Yamagata, Satoshi Seki

Publication number: 20240086662Abstract: An object is to print a high quality image with resistance to print misalignment. To this end, the image processing apparatus generates quantized data for printing a first dot pattern and a second dot pattern in an overlapping manner. The first dot pattern and the second dot pattern are lattice patterns varying in a combination of two basis vectors. In a combined dot pattern obtained by combining the first and second dot patterns, there is a neighboring dot in which a dot in the first dot pattern and a dot in the second dot pattern are arranged at an interval smaller than a lattice spacing. The neighboring dot includes multiple neighboring dots varying in an approach direction.Type: ApplicationFiled: November 16, 2023Publication date: March 14, 2024Inventors: Tsukasa Doi, Hirokazu Tanaka, Satoshi Seki, Junichi Nakagawa, Mayuko Yamagata
