Abstract
A solid-state image sensor according to the present invention includes a number of photosensitive cellsthat are arranged in between the first surfaceof a semiconductor layerand its second surface, which is opposite to the first surfaceand which receives incoming light. As viewed from the photosensitive cells, a reflecting portionis arranged on the same side as the first surfacein order to reflect an infrared ray that has been transmitted through the photosensitive celland make it incident on one of the photosensitive cells. As a result, the intensities of infrared rays to be converted photoelectrically by the photosensitive cellswill be different from each other. And by calculating the difference between the photoelectrically converted signals supplied from the photosensitive cells, the infrared ray component received by each photosensitive cell can be obtained. In addition, by arranging a color filteron the same side as the second surface, an infrared ray component and a color component can be obtained at the same time.
