PURPOSE:To clearly photograph a low-luminance moving body by successively transferring and accumulating charge at the same speed with the image of the moving body on the photosensitive surface of a charge transfer image sensor and by repeatedly inputting and reading data to and from a memory. CONSTITUTION:The image of moving body 4 is projected upon photosensitive part 61 of charge transfer image sensor 6 via lens 5. Then, transfer pulses are sent from transfer pulse generating circuit 7 to terminal 63 synchronizing with the turning of pully 1, and the charge of photosensitive part 61 is transferred to storage part 62 at the same speed as the movement of the image. From pulse generator 7, pulses faster than the said pulses are sent to storage part 62 to perform charge transfer successively, and they are stored in video memory 8 and read out successively to display the image on television receiver 9. Consequently, as far as body 4 is in the visual field of lens 5, the same image is displayed repeatedly, so that the clear image can be obtained from a low-luminance body. |
