Abstract :
CMOS active pixel sensor (APS) is currently the most popular image sensor architecture. In this paper, a CMOS active pixel image sensor with analog-to-digital converter (ADC) is presented. The driving controller of the image sensor is implemented on CPLD chip in the real-time mode, and performed successfully. The detailed design of the image sensor driving circuit is provided. Some codes with VHDL for driving circuit are given. The simulation results show that the final output image from the proposed controller produces the images of satisfactory quality.
