SOLID-STATE IMAGE PICKUP DEVICE FOR PHOTOMETRY AND AUTO- FOCUSING AND IMAGE PICKUP DEVICE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To solve the problems that there is no technology for a multiple auto-focusing, also that appropriate exposure can not be obtained as a photometric function in a back-lighted state and that a photometric range is narrow because an output of a photometric sensor is a linear output.;SOLUTION: A plurality of photoelectric transducer strings 1A to 7A and 1B to 7B for the multiple auto-focusing to a plurality of positions in a photographing area, photoelectric transducers S1 to S7 for spot photometry for performing photometry of a plurality of distance measurement positions in a spot manner, and a photoelectric transducer W0 for full photometry for performing photometry of the whole photographing areas are integrated on the same semiconductor substrate 107.;COPYRIGHT: (C)2003,JPO
