AbstractA custom CMOS image sensor for capsular endoscopy is presented. The complete functionality of the chip is guaranteed through seven signal pins, used for the I2C like input and the LVDS output interfaces. Prototypes have been produced in the UMC 0.18μm-CIS (CMOS Image Sensor) technology both in the monochrome and colour-RGB versions. The imager has been electrically and optically characterized and ex-vivo images have been acquired and evaluated. The results of the characterization show state of the art performance in terms of power consumption (<40mW) and light sensitivity (0.1 lux@555nm for the monochrome imager), comparable to CCD technology
