Video Capture Of Digital Microscope Based On PCI

Nowadays the new technology is changing with each passing day, especially in the field of computer technology, but in the contrary some of traditional techniques were looks like old fashion. Optical telescope combine with the modern Computer technology make the traditional technology keep pace with the new technology. In this case Video Capture of Digital Microscope Based on PCI was born, it made of microscope and computer. In this dissertation, investigate and discuss the connection and communication between microscope and computer, a video capture scheme was proposed and made it.The first step of the system is sending the optical image to CCD camera. The second step is the camera sending the analog video signal to capture card which transform it to digital video signaled. Finally, the digital video signal is sended to computer by PCI bus.Video decoder/encoder chip, PCB board design software, drivers and apply software programming, all of them have many options. Consider of demand, we use SAA7134 as the PCI bus chip and record/encoder chips, design PCB board with Protel 99, write drivers with AVStream multimedia class, program the apply software under the DirectShow capture mode.
