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.

DETAILED DESCRIPTION This invention is directed to the solution of the above stated problem of the prior art.
It is therefore a first object of the invention to provide a camera which facilitates selection of an angle of view and, for this purpose, is provided with display means for displaying image information; and control means for controlling and causing the display means to simultaneously display a plurality of images of different angles of view.
It is a second object of the invention to provide a camera which facilitates selection of an angle of view and comprises display means for displaying image information; and control means for controlling and causing the display means to display a range of view angles and to differentiate a luminance obtained within the view angle range from a luminance obtained outside the range.
It is a third object of the invention to provide a camera which makes the state of angle of view readily perceptible and, for that purpose, comprises display means for displaying image information; and control means for controlling and causing the display means to display an index indicating a view angle range and to selectively display an image in an enlarged state according to the angle of view.
Other objects and features of the invention will become apparent from the following detailed description of embodiments thereof taken in connection with the accompanying drawings.
