    • For an image-capturing unit having a light source and mirrors directing light reflected from a scanned document into a lens condensing the light onto a photoelectrically converting image sensor, a synthetic resin housing. The housing is composed of an open-ended upper frame having a top plate from which sidewalls extend, encompassing an internal space. A mounting surface for anchoring the light-source is formed on the upper side of the upper-frame top plate, and formed on the lower side of the upper-frame top plate is a pedestal on which the lens is supported. Mirror-support projections are formed on the lower side of the upper-frame top plate, or on the upper-frame sidewalls, to support the mirrors from below the lens. With this housing, the influence of heat from the light source on the optics is minimized, improving the mirrors' positional accuracy.

    • An optical system, imaging device and high-resolution processing method precisely generate a high-resolution image by using image data with few pixels. The optical system images an optical image in an imaging unit, the imaged image is spatially discretized so as to be sampled and converted into an image signal, thereby being recorded in a recording unit. A timing at which the image is imaged by the imaging unit is recorded in an imaging timing recording unit. A weight coefficient for the image is calculated by a weight calculating unit by utilizing the timing information obtained by the imaging timing recording unit. A high-resolution processing unit generates a high-resolution image by using the weighted information of the image generated by the weight calculating unit.
