Abstract
A system for providing an improved image of daytime and nighttime scene for a viewer within a vehicle is provided herein. The system includes: a pixel array sensor having a fully masked gate-off capability at a single pixel level, wherein the pixel array sensor is provided with an inherent anti-blooming capability at the single pixel level; wherein each pixel is gated by a corresponding transfer gate transistor having high transfer gate efficiency. The system further includes a gating unit configured to control the transfer gate transistors with pulsed or continuous wave modulated active and passive light sources, to yield a synchronized sensing signal from the sensor, wherein a single pulse is sufficient to cover the entire field of view of the sensor and the entire depth of field of the illuminated scene; and a processing unit configured to receive the synchronized sensing signal and process it.
