Patent Images
1. A video camera comprising:
- a wide-angle optical system configured to receive an optical image;
a high-resolution image sensor coupled to the optical system and configured to convert the optical image to an electronic image, an image processing circuit coupled to the image sensor and configured to receive and process the electronic image, one of its tasks being to correct optical distortion through reference to a table of parameters specific to a combination of the optical system and the image sensor on one or more regions of interest of the captured said electronic image;
a control circuit coupled to said image processing circuit and configured to receive movement and zoom commands and to transmit a signal to said image processing circuit relating the movement and zoom commands specific to a region of interest in said electronic image, wherein the region of interest includes at least a portion of said electronic image; and
an output circuit coupled to said image processing circuit capable of outputting in a plurality of electronic signal formats.

Abstract
A motion video camera that removes the need for mechanical pan, tilt, and zoom apparatus is disclosed. The video camera includes the following. A wide-angle optical system is configured to receive an optical image. An image sensor is coupled to the optical system and is configured to convert the optical image to an electronic image. An image processing circuit is coupled to the image sensor and is configured to receive the electronic image and to execute movement and zoom operations by correcting distortions in the electronic image introduced by the wide-angle optical system and image sensor.
