Abstract
Official abstract text for this publication.
A method and apparatus providing an autofocus routine in a camera apparatus having a processor is disclosed. The camera apparatus is adapted to detect a number of images and communicate image signals representative thereof to the processor. The method includes determining that a degree of change between a first image signal and a second image signal is below a predetermined threshold and responsive thereto, performing the autofocus routine.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of providing an autofocus routine for a camera comprising: determining that a degree of change between a first image signal being a function of a first frame and a second image signal being a function of a second frame detected at the camera is below a predetermined threshold, the determining including analyzing corresponding regions of interest in the first image signal and the second image signal to determine differences between corresponding regi…
