Patent number: 8339681Abstract: The first reading start point D of a front contact image sensor 21 and the second reading start point F of a back contact image sensor 22 are managed using a previously measured sensor-to-sensor distance L. As a result, even if there is a difference in the distance between the sensors, the first and second reading start points D and F will still be a first margin length L1 before the image reading positions A and B of the contact image sensors 21 and 22. Because the beginning of the front image information FD2 and the beginning of the back image information BD2 contained in the back-side image data BD1 in the images captured by the contact image sensors 21 and 22 match, the front image information FD2 can be extracted based on the coordinates of the back image information BD2 contained in the back-side image data BD1.Type: GrantFiled: August 26, 2008Date of Patent: December 25, 2012Assignee: Seiko Epson CorporationInventors: Hideki Nishimura, Takashi Saikawa, Masanori Hayashi

Image reading apparatus, shading correction method therefor, and program for implementing the method
Patent number: 8335021Abstract: An image reading apparatus including a shading correction mechanism that can be formed by fewer component parts than conventional ones, and is increased in the degree of freedom of design, thereby enabling reduction of the size and weight thereof. A contact glass guides an original to an image reading position. A glass holding member holds the glass. A line image sensor reads an image on the original conveyed to the image reading location, through the contact glass. A reference member is disposed at a location different from the image reading location on the contact glass. A moving mechanism relatively moves the line image sensor and the reference member so that the line image sensor can alternatively read the original conveyed to the image reading location and the reference member. A drive section externally drives the moving mechanism to move the line image sensor and/or the reference member.Type: GrantFiled: March 21, 2007Date of Patent: December 18, 2012Assignee: Canon Denshi Kabushiki KaishaInventors: Jun Tanaka, Takashi Machida, Shinobu Kato, Keiji Tsutaoka, Taketo Ochiai, Masahiro Shirai, Shigeru Ikezaki, Hirotaka Watanabe -
