Abstract
A completely electronic color camera for electronically recording an image of an object. The image signals from a solid-state image sensor having color filters are converted to digital form so that the digitized image signals are applied to the same number of coding compression circuits, e.g. differential pulse code modulation circuits, as the kinds of colors of the color filters per scanning line, are subjected to a color separation coding processing and are then stored directly in a memory without performing any additional processing. Error detecting and correctng circuits are provided. Error detecting and correcting data and lens setting data are added to the image data and recorded. The camera is reduced in size, is low in power consumption and requires a reduced memory capacity per frame.
