PURPOSE:To read only specified frequency components, that is, single-emission signals by reading signal charges by connecting filters to the output signal of photoelectric conversion elements. CONSTITUTION:When pulse signals for opening a shutter are emitted while being roughly synchronized with a strobo light, photodiodes 5 read incident light including the strobo light. Next, the signals read by the photodiodes 5 are sent out to high-pass filters 11. The high-pass filters 11 pass only the signals of high-frequency corresponding to the strobo light among the inputted signals and store them in capacities 16. Next, a horizontal shift register 15 outputs the signal charges corresponding to the strobo light stored in the capacities 16 to an output wiring 14 through horizontal selection switches 13. |
