ABSTRACT:
An electronic camera includes a low resolution image sensor responsive to image light for generating a low resolution output signal that is used for camera control functions, such as image viewing, and a high resolution image sensor responsive to image light for generating a high resolution output signal that is used to produce an output image signal. The camera further includes an electronic display driven by the output signal from the low resolution image sensor, a zoom lens for varying the size of the image incident upon the high resolution image sensor and a zoom interpolator responsive to a zoom setting of the zoom lens. The output signal from the low resolution image sensor is then applied to the zoom interpolator, which processes the output signal so that the size of a display image obtained from the low resolution signal corresponds to the zoom setting of the zoom lens.
