Electronic digital still camera for separately storing component video signals in memory
First Claim
1. A digital electronic still camera device to which a semiconductor memory module adapted to store digital data therein is detachably connected, comprising:
- connecting means for detachably and electrically connecting said semiconductor memory module to said camera;
imaging means including a color imaging device having a color filter for imaging a scene through the color filter and producing video signals representative of a scene in the form of image signals associated with filter segments of the color filter;
signal processing means for converting the video signals produced by said imaging means into color component signals and delivering the color component signals to said connecting means in the form of digital signals; and
control means for controlling said imaging means to image the scene, and for controlling said signal processing means to convert the resultant video signals into the color components signals;
said signal processing means comprising color separator means for receiving the video signals produced from said imaging means and for separating the video signals into the color component signals associated with the video signals, producing the color component signals in parallel to each other;
said control means supplying to said connector means, control signals allowing the color component signals to be stored in said semiconductor memory module independently of each other.

Abstract
A digital electronic still camera to which detachably connected is a semiconductor memory module adapted for storage of video signals representing a still image in the form of digital data. The camera includes a connector for detachably and electrically connecting the semiconductor memory module, an imaging subsystem including an image pickup device and adapted for imaging a scene and producing video signals representative of the scene in a dot-sequential manner, a signal processor for converting the video signals produced from the imaging device into component signals and developing the component signals in the form of digital signals, and a control unit for controlling the imaging subsystem and the signal processor to cause the imaging subsystem to shoot the scene, the control unit causing the signal processor to convert the resulting video signals into the component video signals. The control unit supplies control signals to the connector for writing the component signals into the semiconductor memory module.
