System for omnidirectional image viewing at a remote location without the transmission of control signals to select viewing parameters
DCFirst Claim
1. A method of controlling an image display, said method comprising:
- receiving at least one digital video signal corresponding to a captured wide-angle video image, said wide-angle video image having a field of view and being distorted relative to human perception;
selecting two or more views within the wide-angle field of view;
processing the digital video signal to create two or more perspective-corrected video images each corresponding to one of the selected views; and
displaying the perspective-corrected video images simultaneously on the same display monitor.

Abstract
A system for achieving perspective-corrected views at a location removed from the site of the creation of a distorted wide angle image without the transmission of control signals to the site of image creation. Angles of tilt, pan and rotation, as well as degrees of magnification, are achieved without the use of mechanical devices by using transform algorithms. The system provides for the transmission of signals related to an uncorrected image from a site where this distorted image is created, with the transmitted signals being received at one or more processing sites for creating the perspectively-corrected views. Transmission can be via telephone lines, with the system including signal compression and decompression units. Wireless transmission is also utilized where desired.

17. A computer-readable medium having instructions for controlling an image display, said instructions comprising:
-
receiving at least one signal corresponding to a captured wide-angle digital image output from a digital imaging system;
processing two or more selected perspective-corrected portions of the received captured wide-angle digital image; and
simultaneously displaying on the same monitor said two or more selected perspective-corrected portions. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)
