Electronic still camera having two recording stages for recording still-image signals
 An electronic still camera comprising an image-pickup section, and A/D conversion section, a primary recording section, a secondary recording section, a control section, and an image-signal processing section. The image-pickup section generates still-image signals. The A/D conversion section converts the still-image signals into digital signals. The primary recording section records the digital signals. The control section reads the digital signals recorded by the primary recording section, at least during non-operating period of the image-pickup section. The image-signal processing section performs predetermined processing on the digital signals read by the control section, thereby outputting data. The predetermined processing includes at least data compression. The secondary recording section records the data output by the image-signal processing section.
