Abstract
CMOS-based image sensors offer the unique capability of integrating all electronic circuitry of a digital camera on a single chip. The resulting system, hereafter referred to as micro-camera because of its high level of integration, has a great potential in terms of low-power consumption, rendering a wide range of new applications in the field of portable multimedia devices possible. This chapter presents the concepts for the design of such low-power micro-cameras. In a first part, the photodetection principle and the basic CMOS sensor architectures are described. In a second part, the design of low-power Analog to Digital Converters suited for video applications is presented before shortly discussing onchip control and pre-processing functionalities. Two examples of micro-camera realisations are then presented jointly to their specifications, architecture and performances. A summary followed by an outlook on future improvements and applications concludes the chapter.
