Abstract:
1. A single-chip integrated circuit camera system, comprising: an image sensor; one or more external optical elements for focusing light onto the surface of the image sensor; an image-processing element for receiving raw image data and timing signals from the image sensor; a data storage element for storing image data produced by the image-processing element; a communication interface element for controlling input and output data and control signals for the camera; an on-chip multiplexer; a register set; and a test access element for verifying camera internal functionality, said test access element comprises one or more IO pins, wherein the one or more IO pins is either connected to the register set for controlling external functions or connected to internal data inputs and outputs for testing purpose, wherein the connection of the one or more IO pins is controlled by the on-chip multiplexer, wherein said image sensor, said image-processing element, said data storage element, said communication interface, said on-chip multiplexer, said register set and said test access element are on said single chip integrated circuit camera.
