Paper Abstract

This paper describes an analysis system of high-speed photography film. This system has two modes. In the case of the semi-automatic analysis mode, a series of coordinates of the filmed particle can be get by using the cursor. Then the data are processed by the microcomputer and the velocity, acceleration and other movement parameters are printed. In the case of automatic analysis mode, the cursor is used to produce a gate signal which determines the range of digital image. The video signal in this range is given a realtime A/D conversion, then it is put into the image buffer. Microcomputer processes the digital image and gives the coordinate of the marking point, then just like the semiautomatic analysis mode, calculates the velocity, acceleration and other movement parameters.
