Abstract
A video imaging system includes a digital image sensor for performing image capture operations and a digital image processor for performing image processing operations. The digital image sensor includes a sensor array outputting digital pixel data, an image buffer for storing the pixel data, a first processor and a first interface circuit for transferring the pixel data onto a pixel bus. The digital image processor includes a second interface circuit coupled to receive the pixel data from the pixel bus, a frame buffer coupled to store the pixel data, an image processing pipeline for processing the pixel data stored in the frame buffer into video data, and a second processor. The digital image sensor and the digital image processor transfer control information over a control interface bus and the digital image sensor performs the image capture operations independent of the image processing operations performed by the digital image processor.
