Triggering an image processing function
First Claim
1. A method for triggering a processing function for a frame of image data, comprising:
- (a) calculating a first parameter from pixels of a first region of a first frame, the calculating of the first parameter including summing at least one particular component of the pixels of the first region;
(b) calculating a second parameter from pixels of a corresponding second region of a second frame, the calculating of the second parameter including summing the particular component of the pixels of the second region;
(c) comparing the first parameter with the second parameter; and
(d) triggering a function if a particular difference between the first and second parameters is detected, wherein the triggered function pertains to processing at least one later-created frame that is created subsequent to the first and second frames.

Abstract
The invention is directed to apparatus, methods, and systems for calculating parameters from particular pixel components of first and second frames, and triggering a function pertaining to the image processing of a later-created frame if a particular difference between the two parameters is detected. In one embodiment, the present invention is directed to a method for triggering a processing function for a frame of image data. The method includes: (a) calculating a first parameter from pixels of a first region of a first frame; (b) calculating a second parameter from pixels of a corresponding second region of a second frame; (c) comparing the first parameter with the second parameter; and (d) triggering a function if a particular difference between the first and second parameters is detected. The calculating of the first parameter includes summing at least one particular component of the pixels of the first region. The calculating of the second parameter includes summing the particular component of the pixels of the second region. The triggered function pertains to processing at least one later-created frame that is created subsequent to the first and second frames.
