With the development of science and technology, CCD(Charge-coupled Device) has been widely applied in various fields and plays an important role in the modern sensing system, therefore researching a real-time image acquisition and display plan based on CCD device has great significance. This paper introduces an image data acquisition and display system of area array CCD based on FPGA. Several key technical challenges and problems of the system have also been analyzed and followed solutions put forward .The FPGA works as the core processing unit in the system that controls the integral time sequence .The ICX285AL area array CCD image sensor produced by SONY Corporation has been used in the system. The FPGA works to complete the driver of the area array CCD, then analog front end (AFE) processes the signal of the CCD image, including amplification, filtering, noise elimination, CDS correlation double sampling, etc. AD9945 produced by ADI Corporation to convert analog signal to digital signal. Developed Camera Link high-speed data transmission circuit, and completed the PC-end software design of the image acquisition, and realized the real-time display of images. The result through practical testing indicates that the system in the image acquisition and control is stable and reliable, and the indicators meet the actual project requirements.

Design of area array CCD image acquisition and display system based on FPGA

This paper researches the digital high definition imaging technology and successfully designs a digital high definition
camera system .The system takes large array CCD(KAI-2093CM) which conforms to SMEPT 274M standard as
photoelectric transfer device, FPGA+AFE as framework, HD-SDI as transforming interface, and combines with the
current advanced digital high definition video standard. The result of imaging shows that the high definition camera can
realize high definition shooting. The pictures are clear and can be displayed with no stagnation in real time. Moreover,
the small camera with high resolution can be applied for high definition shooting in aerospace and other fields.
