Abstract

PURPOSE:To discriminate a color comparatively easily, exactly and with high accuracy, by constituting 3 kinds of photodetecting parts of plural separated photodetecting units, arraying them so that they are mutually mixed and dispersed between different spectral components, and also providing a common electrode. CONSTITUTION:3 kinds of photodetecting parts for independently photodetecting the spectral components of the 3 primary colors as to every component are constituted of plural separated photodetecting units, respectively, and the photodetecting units of each photodetecting part are arrayed so that they are mutually mixed and dispersed between different spectral components. Also, a common electrode for connecting each photodetecting unit of the same spectral component is provided, so that a photoelectric converting output of each photodetecting unit can be collected and fetched at every spectral component by this common electrode. According to such a constitution, it is possible to discriminate a color exactly and with high accuracy without being influenced by ununiform photodetecting light quantity due to a photodetecting position.
