Line sensor, image reading device, and image forming apparatus

In a line sensor including color filters that are periodically disposed in a light-receiving-element row, a problem called a mixture of colors occurs. A mixture of colors occurs when light that has been transmitted through a color filter differing from a color filter corresponding to a light receiving element is incident upon the light receiving element. In a CMOS sensor 107 including a light-receiving-element row in which a plurality of photodiodes 1204 are disposed side by side in a main scanning direction and a plurality of color filters 1202 that are disposed in correspondence with the plurality of photodiodes 1204, the center of each color filter 1202 is displaced in a direction of the center of the light-receiving-element row from the center of the photodiode 1204 corresponding to the color filter.

Methods and systems for blending line image data streams from a film scanner are disclosed. In one embodiment, a method is provided including receiving multiple data streams from line scan sensors. An overlap position may then be initially selected, which forms an overlap position between two of the data streams. A difference measure may then be calculated between the two data streams within the overlap area. The overlap positions may then be iteratively altered between a plurality of overlap positions, and additional difference measures may be computed for each overlap position. A blending position may then be selected from the plurality of overlap positions, which may correspond to the overlap position with the smallest difference measure. The data streams may then be blended at the selected blending position.

Image scanner

First, second, and third line reading processing is processing of emitting light of each color to first, second, and third line of an original document in first, second, and third lighting order, respectively, and reading reflection light of the emitted light. A color that is first in the first lighting order, a color that is first in the second lighting order, and a color that is first in the third lighting order are different from each other. A color that is second in the first lighting order, a color that is second in the second lighting order, and a color that is second in the third lighting order is different from each other. A color that is third in the first lighting order, a color that is third in the second lighting order, and a color that is third in the third lighting order is different from each other.
