Methods and apparatus related to improved surveillance
First Claim
1. A method of operating an integrated camera assembly including a camera housing, comprising:
- operating a sensor module mounted in said camera housing to generate first fixed size data units, each first fixed size data unit being of a first pixel value size;
performing, within said camera housing, an image processing operation on at least some of said first fixed size data units to produce second size data units, each individual one of the first fixed size data units and second size data units communicating a single pixel value, each second fixed size data unit being of a second pixel value size, said second fixed size data units being of a second fixed size which is smaller than said first fixed size;
generating, within said camera housing, an image output signal from said second fixed size data units;
processing, within said camera housing, at least some of said first fixed size data units, which are also processed by said image processing operation, to perform at least one of a target detection and a target tracking operation; and
outputting, to a device outside said camera housing, said image output signal.

Abstract
A smart camera device incorporates a first processing path for video display processing and a second processing path for detection and/or tracking processing. A sensor device provides input signals including first size data units to both processing paths, at least some of the same input signals are processed by both processing paths. The video display processing generates second size data units which are smaller than first size data units. First size data units provide more information to the detection/processing module than second size data units would have provided if used. IR detection capability is improved by using first size data units. Detection and/or target tracking operations generate control signals used to control the video display processing to enhance the visual perceptibility of a detected target. Detection and/or target tracking operations generate target information signals conveying an indication of target detection, target identification information, target location information, and/or camera control signal.

16. An integrated camera assembly, comprising:
-
a camera housing; a sensor module configured to generate first fixed size image data units, each first fixed size data unit including a total number of bits which equals the number of bits in a pixel value generated by said sensor module; an image processing module located inside said camera housing for performing an image processing operation on at least some of said first fixed size data units to produce second size data units, each individual one of the first fixed size data units and second data units communicating a single pixel value, said second size data units being of a second fixed size which is smaller than said first fixed size, each second fixed size data unit communicating less bits than a first fixed size data unit; a video compression module, located inside said camera housing, coupled to said image processing module configured to generate a compressed image output signal from said second fixed size data units; and a secondary processing module, located inside said camera housing, configured to process at least some of said first fixed size data units, which are also processed by said image processing module, said secondary processing module at least one of a target detection and a target tracking operation. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
