Patent ID: 8896693

Claim:
A camera for monitoring multiple targets, the camera comprising: an image sensor being divided into N non-overlapping sensing areas respectively controlled by N integration times to ensure that each of the sensing areas outputs a properly-exposed sensing signal when the camera is operated to sense a scene, wherein the image sensor includes an array of pixels, each of the pixels includes: M subpixels, coupled respectively to M readout circuits, producing M pixel-level sensing signals, each of the M readout circuits coupled to one of the M subpixels to read out one of the M pixel-level sensing signals therefrom; an integrator provided to combine the M pixel-level sensing signals of the M subpixels to produce a final pixel-level sensing signal of the each of the pixels, wherein M anti-blooming circuits are provided to ensure each of the M pixel-level sensing signals does not exceed a predefined threshold before the M pixel-level sensing signals are combined in the integrator; and N readout circuits, each of the N readout circuits coupled to one of the sensing areas to read out the properly-exposed sensing signal therefrom when the camera is operated to sense a scene including the multiple targets.
