Abstract

The invention provides a high-frame frequency CCD camera system, and relates to the CCD camera system technical field. The camera system comprises a lens, a CCD image sensor, a preamplifier, a video signal processor, a horizontal timing sequence signal generator, a horizontal drive circuit, a vertical drive circuit, an electronic shutter drive circuit, a controller 1, a controller 2, an external memory unit, a Camera Link output unit, a PC, a PCIe acquisition card and display equipment. The high-frame frequency CCD camera system is an integrated system which combines a high-speed CCD drive technology, video processing with data integration; and the system can provide high-speed digital image and can be widely applied to research fields such as moving target capture, transient process record and the like, and has wide application prospect in real-time image motion compensation of large-array low-frame frequency CCD.

Description

technical field [0001] The invention relates to the technical field of CCD camera systems, in particular to a digital CCD camera system with a frame rate up to 1000fps. Background technique [0002] After the advent of photographic technology, people began to imagine how to continuously and quickly capture images of targets, such as car collisions, motion photography during object breaking, and other fields. The earliest high-speed camera system used the method of film sensing to record the image of the target, which can achieve high time resolution, but requires a complex optical-mechanical structure, and the obtained film needs to be washed before it can be judged and used. Due to the use of mechanical shutter , the exposure time interval is long, which cannot meet the occasions of high-speed motion. With the development of the semiconductor industry and integrated circuit technology, especially the CCD sensor has low power consumption, low noise, and small dark current. ...
