Electronic still camera having two recording stages for recording still-image signals
First Claim
1. An electronic still camera comprising:
- image-pickup means for controllably generating still-image signals;
A/D conversion means for converting signals corresponding to said still image signals generated by said image-pickup means into digital signals, and including an output;
image-signal processing means for performing predetermined processing on said digital signals converted by said A/D conversion means, and including an input and an output;
recording means, comprising a recording medium which is detachably provided on a camera body, for temporarily storing said digital signals converted by said A/D conversion means and selectively storing processed digital signals from said image signal processing means, and including an input portion and an output portion;
control means for retrieving said digital signals temporarily stored in said recording means during a non-operation period of said image-pickup means and supplying the retrieved digital signals from the output portion of said recording means to the input of said image-signal processing means and, after said predetermined processing has been performed on the retrieved digital signals, supplying the processed digital signals from the output of said image-signal processing means to the input portion of said recording means; and
a common bus line coupled o the output of said A/D conversion means, the input and output portion of said recording means, and the input and output of said image-signal processing means.

Abstract
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.
