A high-speed non-destructive CMOS image sensor with bi-directional multiple charge transfer active pixel scheme is presented. The high-speed intermediate pictures are used in the motion vector estimation with adaptive iterative search. The sensor has an ability to cancel FPN of intermediate image. The proposed adaptive iterative search with high-speed non-destructive intermediate pictures reduc...

CMOS image sensors are nowadays extensively used in imaging applications even for high-end applications. This is really possible thanks to a reduction of noise obtained, among others, by Correlated Double Sampling (CDS) readout. Random Telegraph Signal (RTS) noise has thus become an issue for low light level applications especially in the context of downscaling transistor size. This paper descr...

Neuromorphic vision processor is an electronic implementation of vision algorithm processor on semiconductor. To image the world, a low-power CMOS image sensor array is required in the vision processor. The image sensor array is typically formed through photo diodes and analog to digital converter (ADC). To achieve low power acquisition, a low-power mid-resolution ADC is necessary. In this pape...
