Abstract:
A solid-state image sensor 31, which has a two-dimensional matrix of a plurality of pixels used to sense the two-dimensional spatial distribution of radioactive rays, light rays, electrons, ions, or the like, is provided with an aperture 34 that extends through a substrate 33b of an image sensing unit 33 on which the pixels are arranged, and a signal transfer path that connects signal transfer electrodes 33d for reading images of the respective pixels kept clear of the aperture 34. Furthermore, the image sensing unit 33 is divided into at least two regions by a boundary including the aperture 34, and these regions have individual signal read registers. With this structure, the image sensor serves as both an image sensor for sensing the two-dimensional distribution of radiation or the like, and an aperture for passing such radiation.

PURPOSE: A spectro-colorimetric device and an image forming device having the same are provided to obtain a stable color by a color unit sensor even though a color difference between colors of a color image formed on a paper and directed colors is existed. CONSTITUTION: A spectro-colorimetric device comprises a concave surface reflective type diffractive device(160), a linear sensor(170), a housing(100), and an opening(102). The concave surface reflective type diffractive device is composed to split incident lights. The linear sensor comprises a plurality of photoelectric conversion elements. The housing supports the concave surface reflective type diffractive device and linear sensor. The opening formed in the side wall of the housing is arrayed so that spectrums split by the concave surface reflective type diffractive device are passed through.

Abstract:
A solid state image pickup device (31) in which a plurality of picture elements are arranged in two dimensions to pick up the image of the distribution in two-dimensional space of radiative ray, light beams, electrons, ions, etc., and which is characterized by an opening (34) piercing a substrate (33b) being provided at the roughly center of an image pickup part (33) where the picture elements are arranged, and a charge transfer path to connect charge transfer electrodes (33d) to read out the image of each picture element with one another being wired, avoiding the opening (34). Furthermore, the image pickup part (33) is divided into at least two regions with the boundary between them lying partially in the opening (34), and each region has an exclusive register for charge readout. Hereby, this image pickup device doubles as an image pickup device to pick up the two-dimensional distribution of radiative ray, etc. and an aperture to this radiation.
