VIRTUAL SPORTS SYSTEM FOR CONTROLLING CAMERAS ACCORDING TO ENVIRONMENTAL BRIGHTNESS TO OBTAIN GOOD BALL IMAGES

摘要

PURPOSE: A virtual sport system for obtaining high quality ball images by a camera according to brightness is provided to calculate the kinetic velocity and height of a ball when the ball is on the air. CONSTITUTION: A virtual sport system comprises a picturing unit(100) and a simulator. The picturing unit comprises a camera(110) for obtaining the image of a ball. The simulator calculates the physical quantity of the ball based on a ball image. The picturing unit comprises a control unit(130). The control unit obtains the information of an image from images obtained from the camera and determines a control signal to control exposing time and the image of the camera based on the information of an image.
