1. An electronic camera for recording still images comprising:
- a two dimensional image sensing array comprising a predetermined number of discrete image sensing areas;
a two dimensional image storing array comprising a predetermined number of discrete image storing areas, said predetermined number of discrete image storing areas being substantially less than said predetermined number of discrete image sensing areas;
means for providing a viewfinder display;
means for recording image data on a select recording medium; and
means for controlling the sampling and transfer of image data from said image sensing array to said image storing array for storage therein during a preview mode of operation and for subsequently transferring said image data stored in said image storing array to said viewfinder display means to provide a visual display of said image data during said preview mode of operation, said image data control means being operable during a record mode of operation to control the transfer of image data from said image sensing array to said image recording means to enable said image data to be recorded by said recording means.

Abstract
An electronic camera for providing a photographic quality still print includes a viewfinder display in which the scene to be photographed may be viewed for composition at a standard television transfer frame rate without the provision of additional buffer memories. The electronic camera comprises an integral charge coupled device (CCD) sensing configuration which operates to sense the image to be recorded in a preview mode of operation and to provide a real time digital buffer memory during a succeeding review mode of operation in order to display the recorded scene in the viewfinder at a standard television frame transfer rate.

8. An electronic camera for recording still images comprising:
-
a two dimensional image sensing array comprising a predetermined number of discrete image sensing areas; means for providing a viewable display; means for recording image data on a select recording medium; and means for controlling the transfer of image data from said image sensing array to said image recording means to enable said image data to be recorded by said recording means during a record mode of operation and for controlling the sampling and transfer of image data from said recording means to said viewable display by way of said image sensing array to provide a visual display of said recorded image data during a review mode of operation wherein;
said image data sensed by said image sensing array is in analog format;
said image data control means comprises means for converting the image data received from said image sensing array during said record mode of operation to a digital format for recording by said recording means, and said image sensing array operates to momentarily store image data in digital format sampled from said recording means during said review mode of operation. - View Dependent Claims (9, 10, 11, 12)
