Patent number: 7894105Abstract: An image reader includes two rows of image reading element arrays, that is, a first image reading element array and a second image reading element array, and a first rod lens array and a second rod lens array, disposed in correspondence with the first and second image reading element arrays and having different focal positions, in order to read an image on a transmission original in optimal focus with a CIS scanner using the rod lens arrays as when an image on a reflection original is read. The second image reading element array provides higher resolution, and has a shorter reading length. The focal length of the second rod lens array is greater than that of the first rod lens array.Type: GrantFiled: January 18, 2005Date of Patent: February 22, 2011Assignee: Canon Kabushiki KaishaInventor: Mitsuru Amimoto

Patent number: 6657748Abstract: In an image reading apparatus, required capacity of a memory for storing shading correction data is reduced, as well as the width of a standard white board for generating the shading correction data is shortened. These are achieved by sequentially generating the shading correction data corresponding to respective R, G and B components, independently, to share a data storage area necessary for generating shading correction data, further, by reversing a scanning direction when scanning a standard white board while illuminating it with light of the respective color components on generating the shading correction data.Type: GrantFiled: May 25, 1999Date of Patent: December 2, 2003Assignee: Canon Kabushiki KaishaInventors: Hisao Okita, Mitsuru Amimoto, Takashi Sakai, Kimihiko Fukawa

Patent number: 6545777Abstract: In a color scanner, three LEDs for irradiating an original with colors R, G, and B are so switched as to sequentially emit light for respective predetermined emission times, and a reading unit is moved to read the original. This invention reduces color misregistration occurring due to the differences between irradiation positions resulting from the switching. Of the RGB LEDs, the start point of the emission time of the G LED having the longest emission time is matched with the end point of the emission time of the R LED before this G LED. The B LED emits light after the end point of the emission time of the G LED.Type: GrantFiled: June 17, 1999Date of Patent: April 8, 2003Assignee: Canon Kabushiki KaishaInventor: Mitsuru Amimoto
