PURPOSE:To obtain a stable picture, by using a charge transfer part itself as a buffer memory to refresh partially a picture signal repeatedly. CONSTITUTION:A photoelectric charge corresponding to the photographed picture of each picture element is stored in the photo detecting part of a solid-state image pickup element 20. In recording to a recording device 21, the picture signal is circulated in a transfer register of the solid-state image pickup element 20 because terminals 5 and 8 are connected. The frequency of driving pulses is brought into the monitor (television) band to output one-screen components of the picture signal repeatedly to a terminal 22, and one-screen components of still picture are reproduced successively on the monitor device. A part of one screen, namely, one-line components of the picture signal are read out to a register 23 from the storage device 21, and new one-line components of the picture signal are transferred from the register 23 to the register in the solid-state image pickup element 20 synchronously with this readout, and thus, the picture signal is refreshed. |
