Abstract
An improvement to an electronic zoom system allows operation with a single vidicon camera and an electronic storage means to provide a viewer with zoom capability and a display that has effectively no loss of resolution.
Claims10
Apparatus comprising:
- radiation sensing means providing an output signal indicative of the radiation received thereby;
- wide field of view means;
- narrow field of view means;
- means mounting said wide field of view means and said narrow field of view means in first and second interchangeable positions with respect to said radiation sensing means so as to direct radiation from a scene being viewed to said radiation sensing means;
- changing means operable to interchange said wide field of view means and said narrow field of view means;
- storage means having an input connected to receive and store the output of said radiation sensing means and to produce an output representative of the stored output of said radiation sensing means;
- and
- connective means connecting the output of said radiation sensing means to a first output connection while connecting the output of said storage means to a second output connection when said wide field of view means is in the first interchangeable position and connecting the output of said radiation sensing means to the second output connection while connecting the output of said storage means to the first output connection when said narrow field of view means is in the first interchangeable position.

Apparatus for use with an electronic zoom system which system has a first input for receiving a wide field of view signal, a second input for receiving a narrow field of view signal and a third input for receiving a zoom command signal comprising:
- a camera having a broad field of view lens, having a narrow field of view lens and providing a first output representative of the image viewed by the camera;
- changing means operable to interchange the wide field of view lens and the narrow field of view lens into operable position with respect to said camera;
- storage means having an input to receive input signals representative of an image, operable to store an image created from the input signals and to provide a second output representative of the image stored in said storage means;
- first switch means operable in a first condition to connect said camera to the first input of the electronic zoom system so that the first output provides the wide field of view signal thereto and in a second condition to connect said camera to the second input of the electronic zoom system so that the first output provides the narrow field of view signal thereto;
- second switch means operable in a first condition to connect said storage means to the second input of the electronic zoom system so that the second output provides the narrow field of view signal thereto and in a second condition to connect said storage means to the first input of the electronic zoom system so that the second output provides the wide field of view signal thereto;
- and
- third switch means operable in a first condition to connect said camera to the input of said storage means so that the first output provides the input signal thereto.
