摘要： A photoelectric conversion element comprises: a plurality of pixels, each of which performs photoelectric conversion and outputs an analog signal; an analog processing unit that sequentially processes, on a pixel-to-pixel basis, the analog signals output from a pixel group including the pixels; and a signal supply unit that supplies a signal needed for preliminary operation to the analog processing unit so as to enable the analog processing unit to perform the preliminary operation before the analog processing unit starts to process the analog signals output from the pixel group.

摘要： An imaging sensor includes multiple light-receiving elements, which are for multiple colors, configured to conduct photoelectric conversion and multiple power supply lines configured to supply a power supply voltage from a power supply source to the light-receiving elements. The light-receiving elements of each of the colors are aligned in one direction. Portions extending between the power supply source and the respective light-receiving elements of the multiple power supply lines are substantially identical in shape on at least a per-color basis.

摘要： An image reading device includes a white reference member, a generating unit, a representative-value storage unit, a reproducing unit, and a normalizing unit. The white reference member reflects a light emitted from a light source. The generating unit generates pseudo data on the basis of the light reflected by the white reference member with respect to each pixel area. The representative-value storage unit stores therein a representative value of each pixel area of the pseudo data. The reproducing unit reproduces the pseudo data on the basis of the representative values. The normalizing unit normalizes results of photoelectric conversion of at least any of pixels on the basis of the pseudo data, thereby creating a criterion for determining the presence or absence of an original.

摘要： An image reading device includes a shooting unit, a light source unit, a shooting controller, and a combining unit. The light source unit sequentially irradiates the bound document with light from first and second irradiation positions opposing each other with respect to a first straight line orthogonal to a direction of a binding portion of the document. The shooting controller controls the shooting unit to shoot a first region positioned at the second irradiation position side on the document when the light source unit irradiates the document with light from the first irradiation position, and controls the shooting unit to shoot a second region containing a region other than the first region on the document when the light source unit irradiates the document with light from the second irradiation position. The combining unit combines a shot image of the first region and a shot image of the second region.
