PURPOSE:To improve resolution by forming a means for simultaneously reading out electrostatic charges accumulated in two photodetecting elements adjacently arranged in the vertical direction from the 1st and 2nd horizontal transfer registers as video signals successively in the order of charge values accumulated in photodetecting elements arranged in the horizontal scanning direction. CONSTITUTION:Charges accumulated in two photodetecting elements adjacently arranged in the vertical direction and arrayed as two lines on the horizontal scanning direction out of plural photodetecting elements 2 are simultaneously and serially horizontally transferred to horizontal transfer CCDs 9, 10. A signal extracted from the horizontal transfer CCD 9 through an amplifier 11 and a terminal 13 as a video signal synthesized alternately and time sequentially at every photodetecting element pitch from a video signal based upon yellow light and a video signal based upon cyanine light is supplied to sample holding circuits 18, 19. On the other hand, a signal extracted from the CCD 10 through an amplifier 12 and a terminal 14 as a video signal synthesized alternately and time sequentially in each photodetecting element pitch from a video signal based upon white light and a video signal based upon green light is supplied to sample holding circuits 20, 21.
