PURPOSE:To execute the band conversion without using a special band converter, by providing an input part, to which the picture signal is inputted from the external, in the charge transfer part of a solid-state image pickup element and making driving frequencies for input and readout different from each other. CONSTITUTION:The picture signal from the external applied to an input terminal 8 is inputted to a register 10 through a voltage-charge converter 9. After the transfer to the register 10 is terminated, the charge of the register 10 is transferred to a register 2, and the input of the external picture signal to the register 10 is restarted. This operation is repeated to store the external picture signal in the register 2. The picture signal stored in the register 2 is transferred to a register 3 by readout pulses having a frequency different from that of driving pulses for the input to the register 10 and is outputted from a terminal 5 to a recording device (which is not shown in the figure) through a charge-voltage converter 4. |
