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.
