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： 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： A photoelectric conversion element includes a plurality of light-receiving elements, a plurality of pixel circuits, and a plurality of storage units. The light-receiving elements are aligned in a predetermined alignment direction for each color of light to be received, to receive and convert the light into electric charge. The pixel circuits are disposed respectively adjacent to the plurality of light-receiving elements, to convert the electric charge generated by the corresponding light-receiving element into a voltage signal. The storage units are disposed respectively corresponding to the plurality of the pixel circuits, to store therein the voltage signal generated by the corresponding pixel circuit. The storage units are disposed in an adjacent region that is adjacent to a photoelectric conversion region in which the light-receiving elements and the pixel circuits are disposed.

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.
