PROBLEM TO BE SOLVED: To provide a photoelectric converter capable of detecting a photographed body with a fine pattern, high in focus detecting accuracy and improved in responsiveness and low in luminance marginal performance. SOLUTION: Photodiodes PD1-PDn are so constituted as to be switched in the sample pitch by the changeover of switches SW12, SW23, SW34, SW2P, SW3P, SW4P, and the like so as to be able to act being switched into the case of independently inputting to image amplifying circuits E1-En photodiode by photodiode and into the case of inputting to the image amplifying circuits E1-En at the quadruple sample pitch, that is, with the units of photodiodes PD1-PD4, PD5-PD8,... as the sample pitch. |
