Abstract:
A system and method that provides adaptive IR illumination for a camera. In some implementations, IR illumination adapts to the objects in a scene being monitored and IR illumination adaptation may be implemented in conjunction with automatic exposure and other exposure adjustment methods. Some implementations include: illuminating a scene using a first IR illumination power; capturing a first image of the scene with a camera; and determining whether a first region of the first image is underexposed or overexposed. When the first region is underexposed, the scene is illuminated at a second power level greater than the first illumination power and a second image is captured. When the first region is overexposed, the scene is illuminated at a third power level that is less than the first illumination power and a third image is captured. The operations are repeated until scene illumination is satisfactory.

Claim (Index 1):
A method implemented in a camera system, comprising:\n when the camera system is in a night mode, wherein the camera system includes a lens assembly, an image sensor, a memory for storing image data from the image sensor, and an IR illuminator:\n illuminating by the IR illuminator a scene using a first IR light at a first illumination power; \n capturing by the image sensor a first image of the scene within a field of view of the lens assembly and storing in the memory first image data corresponding to the first image; \n determining whether a first region of the first image has an illumination level below a lower illumination threshold, resulting in loss of image detail in the first region due to underexposure, or an illumination level above an upper illumination threshold, resulting in loss of image detail in the first region due to overexposure; \n in response to the determining,\n (A) when the first region has the illumination level below the lower illumination threshold:\n illuminating by the IR illuminator the scene using a second IR light at a second power level that is greater than the first illumination power; \n capturing by the image sensor a second image of the scene; and \n storing in the memory second image data corresponding to the second image; and \n \n (B) when the first region has the illumination level above the upper illumination threshold:\n illuminating by the IR illuminator the scene using a third IR light at a third power level that is less than the first illumination power; \n capturing by the image sensor a third image of the scene; and \n storing in the memory third image data corresponding to the third image.
