Object-of-interest image capture
First Claim
Patent Images
1. A method for object-of-interest image capture, comprising:
- capturing a current image using a local exposure value determined from luminance readings of pixels within an object region of an object-of-interest of a previous image;
determining an object region of the object-of-interest in the current image;
calculating a contrast measurement of the object region; and
identifying the current image as having an optimized object region when an iteration measure meets a criterion.

Abstract
A method and apparatus for object-of-interest image capture accomplishes the functions of capturing (120) a current image, determining (125) an object region of the object-of-interest in the current image, calculating (130) a contrast measurement of the object region, and identifying (135) the current image as having an optimized object region when an iteration measure meets a criterion. The current image is captured using a local exposure value determined from luminance readings of pixels within an object region of an object-of-interest of a previous image.
