Abstract

A miniaturized camera which is programmable and provides low power consumption. An active pixel image sensor used in the highly miniaturized camera provides improved imaging functionality as well as reduced power consumption, extending the possible life time of the camera system. The spread spectrum nature of transmission and reception improves data integrity as well as data security. The ability of the highly miniaturized wireless camera to receive commands as well as transmit image data provides improved functionality and a variable rate of power consumption to be set according to the application and needs of the situation.
