Patent number: 11949834Abstract: An image reading device includes linear image sensors that are arranged so that adjacent image sensors include an overlapping region in which portions of reading regions of the adjacent image sensors overlap in a main scanning direction, and a buffer unit for read image data. Image data of each overlapping region are generated by synthesizing first image data obtained by a first linear image sensor and second image data obtained by a second linear sensor, the first linear image sensor and the second linear sensor being adjacent in the main scanning direction. Image data of the predetermined line is generated based on image data in which the image data of each overlapping region are excluded from the image data stored in the buffer unit and the image data of each overlapping region. The processing is repeatedly executed in a sub-scanning direction.Type: GrantFiled: December 2, 2022Date of Patent: April 2, 2024Assignee: Canon Kabushiki KaishaInventors: Tomoya Teraji, Katsutoshi Miyahara, Takehiko Kasamatsu, Shota Nonaka
