Video image formatting technique
First Claim
1. A method for establishing a pan and scan pixel coordinate (P) that defines an image capture window useful for formatting an image (10) having a first aspect ratio to yield an image having a second aspect ratio, comprising the steps of:
- examining an incoming image frame to ascertain a location therein of most pertinent activity; and
establishing the pan and scan pixel coordinate in accordance with the location in the incoming image frame of the most pertinent activity.

Abstract
The formatting of a video image frame (10) having a first aspect ratio to yield an image frame having a different aspect ratio is facilitated by establishing a pan and scan pixel coordinate (P) within the image that defines an image capture window for formatting purposes. A predictor (22) determines the pan and scan pixel coordinate by examining the image frame to determine the location therein of the most pertinent activity. The predictor (22) determines the location of the most pertinent activity by examining at least one of: video data, audio data, and other data such as closed captioning information.

17. A method for formatting an incoming image frame having a first aspect ratio to yield a formatted image frame having a second aspect ratio, comprising the steps of:
-
establishing within the image frame a pan and scan pixel coordinate (P) that lies substantially coincident with a location in the image frame associated with most pertinent activity, and panning and scanning the incoming image frame with an image capture window centered about the pan and scan pixel location, to format incoming image frame to yield the formatted image frame. - View Dependent Claims (18, 19)
