Mulitple gated pixel per readout

摘要

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.

1. A method of providing an improved image of daytime and nighttime scene, the method comprising:
configuring a pixel array sensor to have a masked gate-off capability at a single pixel level, providing the pixel array sensor with an inherent anti-blooming capability at the single pixel level, wherein each pixel is gated by a corresponding transfer gate transistor having a high transfer gate efficiency, configuring a gating unit to control the transfer gate transistors of the pixel array sensor so as to accumulate a sequence of multiple exposures per single readout of the pixel based on specified exposure parameters, and configuring the pixel sensor array to operate in at least one mode other than gating.
