Image Sensor Pipeline CMOS WDR sensors have no on-chip image pipeline processing and output the image data in RAW/Bayer format at up to 20 bits per pixel. An imaging pipeline consists of the image sensor itself and an image signal processor (ISP) chip, both of which are hard-wired to produce high-resolution, low-noise, color-corrected photographs. However, various firmware limitations require acrobatics in the pipeline to achieve requested encodings. To be able to utilize ISP, we need a camera with CSI interface. Examples of such functions are debayering, demosaicing, noise reduction, etc. Work on Nest device platform software, with a focus on camera sensor/ISP, imaging pipeline and video processing. Traditional image signal processing (ISP) pipeline consists of a set of individual image processing components onboard a camera to reconstruct a high-quality sRGB image from the sensor raw data.
