Abstract
Abstract A camera includes an electronic zooming feature to selectively transform an image actually received at an image sensor into a displayed image at a photographing plane according to different angles of view corresponding to different zooming ratios. The image actually received is converted to binary data and stored in memory according to address coordinates. Electronic zooming is performed without affecting the optical system of the camera by reading stored data from memory to obtain an area defined by selected address coordinates and displaying an image corresponding to a desired focal length.
