ABSTRACT:
The apparatus (10) performs pan and zoom functions in conjunction with an electronic image sensor (18) with an image area (72, 92, 112) in which a plurality of lines and columns of pixel data are generated by impinging light. Pan and zoom commands are generated by an input device (12) in response to operator input or commands from a microprocessor and the like. A vertical indexing circuitry (14, 16, 64, 72, 76, 86) is coupled to the image sensor (18) and selectively transfers from the image area (72, 92, 112) a number of successive lines of pixel data in response to the pan and zoom commands. A horizontal indexing circuitry (14, 16, 62, 66, 80, 100, 116) is coupled to the vertical indexing circuitry for receiving the selected number of successive lines of pixel data and further selecting a number of successive columns of pixel data therefrom for display in response to the pan and zoom commands.
