    摘要: In a line sensor including color filters periodically disposed in a light-receiving-element row, a “mixture of colors” problem occurs when light that has been transmitted through a color filter differing from a color filter corresponding to a light receiving element is incident upon the light receiving element. To prevent the “mixture of colors” from occurring, in a CMOS sensor 107 including a light-receiving-element row in which a plurality of photodiodes 1204 are disposed side by side in a main scanning direction and a plurality of color filters 1202 that are disposed in correspondence with the plurality of photodiodes 1204, the center of each color filter 1202, other than the center color filter that corresponds to the center photodiode of the light-receiving-element row, is displaced in a direction toward the center of the light-receiving-element row from the center of the photodiode 1204 corresponding to the color filter.

    摘要: A photoelectric conversion apparatus includes a semiconductor substrate having one principle surface including recessed portions, and insulation bodies in the recessed portions. The semiconductor substrate includes photoelectric conversion elements each of which includes a first semiconductor region of a first conductivity type, a second semiconductor region of a second conductivity type, and a third semiconductor region of the second conductivity type which has at least a portion disposed nearer to the principle surface relative to the second semiconductor region. The second semiconductor region has a polarity of signal charge. The second semiconductor region is in contact with the first and third semiconductor regions. Signal charge paths are disposed between the recessed portions in a cross section perpendicular to the principle surface. At least one of the second and third semiconductor regions is positioned in directions of at least two of the signal charge paths.

    摘要: A sensor has first pixels each including one of red, green and blue color filters, and second pixels each including one of red, green and blue color filters. In the first and second pixels including color filters of the same color, light transmittances of the light transmissive portions are different. A light transmittance of the light transmissive portion of the first pixel including the red color filter is lower than that of the light transmissive portion of the first pixel including the green color filter, and a light transmittance of the transmissive portion of the first pixel including the green color filter is lower than that of the light transmissive portion of the first pixel including the blue color filter.
