ABSTRACT:
The present invention is to enable phototaking operation even during the signal transfer from the buffer to the final recording medium. Image pickup device 14 converts the optical image into an electrical signal. A recording process circuit 20 applies a process, such as compression, to the taken image. The image information processed by the circuit 20 is recorded in a rigid disk device 26, through a buffer memory 22 and an interface 28, under the control of a memory control circuit 24. A system control circuit 30 enables the continuous recording operation or the single recording operation, respectively when the remaining capacity of the memory 22 is at least equal to V1, or less than V1. Also the circuit 30 interrupts the continuous recording operation or reduces the rate of the continuous recording, if the remaining capacity of the memory 22 reaches V2 (<V1) in the course of a continuous recording operation. V2 corresponds to a memory capacity of image information of at least an image frame.
