The geometrical Modulation Transfer Function (MTF) of CMOS APS (active pixel sensor) is analyzed in this paper. Advanced APS have been designed and fabricated where different pixel shapes such as square  rectangle and L shape  were placed  because the amplifier circuit and other function circuits inter pixel of APS take up some pixel area. MTF is an important figure of merit in focal plane array imaging sensors. Research on analyzing the MTF for the proper pixel shape is currently in progress for a centroidal configuration of a target position. MTF will give us a more complete understanding of the tradeoffs opposed by the different pixel designs and by the signal processing conditions. Based on image sensor sampling and reconstructing model  the MTF expression of any active pixel shape has been deduced in this paper. According to actual pixel shape  three different active area pixels were analyzed  they were square  rectangle  and L shape  their Fill Factor (FF) is 30%  44% and 55%  respectively. Results of simulation experiments indicate that different pixel geometrical characteristics contribute significantly to the figures of their MTF. Different geometrical shape of active sensitive area of pixel and different station in pixel would influence MTF figures. The analysis results are important in designing better APS pixel and more important in analyzing imaging system performance of APS subpixel precision system.

CMOS image sensors now become increasingly competitive with respect to their CCD counterparts  while adding advantages such as no blooming  simpler driving requirements and the potential of on-chip integration of sensor  analog signal conditioning circuits  A/D converter and digital processing functions. Furthermore  CMOS sensors are the best choices for low-cost imaging systems. An image identification system based on CMOS image sensor is used to identify the seal images that include fingerprint  and then determine whether the seal is fake or not. The system consists of a color CMOS image sensor (OV2610)  a buffer memory  a CPLD  a MCU (P89C61X2)  a USB2.0 interface chip (ISP1581) and a personal computer. The CPLD implement the logic and timing of the system. The MCU and the USB2.0 interface chip deal with the communications between the images acquisition system and PC. Thus PC can send some parameters and commands to the images acquisition system and also read image data from it. The identification of the images of seal is processed by the PC. The structure and scheme of the system are discussed in detail in this paper. Several test images of seal taken by the system are also provided in the paper.
