Short summary
Applications in the fields of e.g. industrial image processing, image based robotic control systems and autonomous driving require high dynamic range image sensors. Conventional linear CMOS image sensors only have a limited dynamic range. To extend the dynamic range the concept of a linear self-reset pixel is implemented with several pixel variants being realized and characterized on a CMOS chip. A second topic is the design with digital readout of a cluster structure composed of a pixel matrix.
