A method and a system for operating an imager during image capture of an object under a wide range of ambient light intensities so as to provide a controlled, output image signal for image recognition. The imager includes an imaging circuit, having an imaging array on a die and light detectors also located on the die adjacent to, the imaging array for sensing the intensity of the illumination on the object and, generating signals representing the intensity of the illumination sensed at each, detector.

Why it's free to use
- Filed January 9, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended January 9, 2021.

- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
