ABSTRACT:
The present invention pertains to an integrated circuit. The integrated circuit comprises a sensor which produces a sensor signal corresponding to energy received. The integrated circuit is also comprised of a processing element connected to the sensor which receives the sensor signal only from the sensor and produces a processing signal corresponding to the sensor signal. Additionally, there is a memory connected to the processing element for receiving the processing signal and storing the processing signal. In a preferred embodiment, the integrated circuit is also comprised of a buffer connected to the sensor and the processing element for receiving the sensor signal and buffering the sensor signal for reception by the processing element. The sensor can include a photodiode which receives the sensor signal corresponding to light energy it receives. In a more preferred embodiment, the integrated circuit includes a photosensitive array comprised of cells for use in a light stripe rangefinder wherein a plane of light is moved across a scene. Each cell is able to detect and remember the time in which it observes the light intensity thereon.
