1. A single chip camera device, comprising:

  • a substrate, having integrated thereon an image acquisition portion and a control portion, both of which are formed using a logic family that is compatible with CMOS;

    said image acquisition portion integrated in said substrate including an array of active pixel type photoreceptors, where each element of the array includes both a photoreceptor and a readout amplifier integrated within the same substrate as the photoreceptor;

    said control portion integrated in said substrate including a signal controlling device, controlling said photoreceptors to output their signals,said control portion also including, integrated in said substrate, a timing circuit integrated within the same substrate that houses the array of photoreceptors, controlling a timing of operation of said array of photoreceptors, and further comprising double sampling charge storage elements on said substrate.
