Abstract
An electronic viewfinder for an electronic imaging still camera may be selectively operated in either an electronic viewfinder mode in which electronic image data sensed by the photoresponsive sensing elements of the camera is transmitted to provide a video display of the scene within the field of view of the camera or, alternatively, an optic viewfinder mode in which the image defining scene light rays are optically transmitted for direct viewing of the scene within the field of view of the camera by the camera operator. The optic viewfinder mode of operation is automatically initiated during the time in which the image defining data is transmitted from the image sensing elements to the image data storing elements and the viewfinder is inoperative to provide its video display.
