    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.

    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: 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.
