Abstract: This paper presents implementation of a low-power tracking CMOS image sensor based on biological
models of attention. The presented imager allows tracking of up to N salient targets in the field of view. Employing
"smart" image sensor architecture, where all image processing is implemented on the sensor focal plane, the
proposed imager allows reduction of the amount of data transmitted from the sensor array to external processing
units and thus provides real time operation. The imager operation and architecture are based on the models
taken from biological systems, where data sensed by many millions of receptors should be transmitted and
processed in real time. The imager architecture is optimized to achieve low-power dissipation both in acquisition
and tracking modes of operation. The tracking concept is presented, the system architecture is shown and the
circuits description is discussed.
