Abstract

PURPOSE:To enable measurement by freely weighting respective parts of a screen by using one photoelectric converter having a wide photodetection surface and then by providing shielding masks for optical weighting corresponding to the position of the converter. CONSTITUTION:Into N type silicon chip 10, impurities are diffused to form P layer 11 and photodetection surface 7a of a photodiode constituted with thin P-N junction is weighted according to the importance of its position while the appearance frequency of a primary object, specific object, etc., are considered. This weighting is performed by providing shielding masks 8 at respective parts of photodetection surface 7a. Only light incident to a part with no shielding mask 8 is photoelectrically converted. Consequently, respective parts of the screen can be measured by being weighted freely and the structure can also be simplified.
