Patent number: 11153458Abstract: An image processing apparatus includes a reading unit and a controller. The reading unit radiates light to a target from two directions with different angles and reads images of the target. The controller performs, when controlling the reading unit to acquire the two images of the target, control such that a resolution of the image read by radiating the light to the target from one of the two directions is lower than a resolution of the image read by radiating the light to the target from the other one of the two directions.Type: GrantFiled: March 26, 2020Date of Patent: October 19, 2021Assignee: FUJIFILM Business Innovation Corp.Inventors: Kazuhiko Horikawa, Ryosuke Yonesaka

Patent number: 10999478Abstract: An image processing apparatus includes a receiver and a correcting unit. The receiver receives a first read value and a second read value. The first read value indicates a result of reading a first color by a reader from a recording medium in which the first color is applied to a first area in which in-plane density unevenness is confirmable within the recording medium. The second read value indicates a result of reading a second color by the reader. The second color is different from the first color and is applied to a second area that is substantially the same as the first area in a superimposed manner. The correcting unit corrects in-plane density unevenness of the second color applied to the first color in the superimposed manner based on the first read value received by the receiver and the second read value received by the receiver.Type: GrantFiled: July 26, 2019Date of Patent: May 4, 2021Assignee: FUJI XEROX CO., LTD.Inventors: Tomohiko Takei, Koichi Matsubara, Yuma Motegi, Kazuhiko Horikawa, Ryosuke Yonesaka
