ABSTRACT:
An active pixel sensor is used to replace a charge coupled device (CCD) image sensor. The active pixel sensor may be operated in a low voltage environment and the power consumption is lower than that in the conventional CCD image sensor and the CMOS active pixel sensor which is now developed by current industry. The active pixel sensor of the present invention has a lower cost and may be applied to a portable system.
