A method includes receiving, by a system-on-a-chip (SoC) from a camera mounted on a vehicle, a first image and transmitting, by the SoC to a display circuit over an interface cable, the first image. The method also includes receiving, by the SoC from the display circuit, a feedback signature corresponding to the first image. Additionally, the method includes detecting, by the SoC, an error, in response to determining that the feedback signature does not match the transmission-side signature and transmitting, by the SoC to the display circuit, a second image, in response to determining that the feedback signature matches the transmission-side signature.

A method of WDR imaging. Exposure times (ETs) are set for first and second frames for an image sensor to avoid second frame saturating by setting a second ET&#x3e;1/a PWM frequency applied to an LED illuminating a scene to generate second longer ET pixel data (PD). The first frame has first PD and a first ET&#x3c;the second ET. A high and low intensity threshold are calculated from a full well capacity. Raw image signals are obtained originating from the image sensor of the scene. Flicker is detected by comparing the first and second frame intensity values to the high and low threshold to determine whether the first PD is flickering data. A WDR merge is performed by selecting weightings from the first and second PD for each pixel including increasing weighting of the second PD for flicker. A final image is formed from the weighted WDR merge.

WDR imaging with LED flicker mitigation

Method and system to improve the performance of a video encoder. The method includes processing an initial video signal in a front-end image pre-processor to obtain a processed video signal and processor information respecting the signal, providing the processed video signal and the processor information to a video encoder, and encoding the video signal in the video encoder according to the processor information to provide an encoded video signal for storage. The system includes a video pre-processor connectable to receive an initial video signal. The video encoder in communication with the video pre-processor receives a processed video signal and a processor information. A storage medium in communication with the video encoder stores an encoded video signal.
