MONITORING SYSTEM AND METHOD THEREOF USING PC HAVING SCREEN ACQUISITION BOARD

摘要

PURPOSE: A monitoring system and a method thereof using a PC(Personal Computer) are provided to mount a screen acquisition board to the PC and to connect the board to a camera member, thereby monitoring a monitoring region through a screen inputted from the camera. CONSTITUTION: A camera member(200) is mounted to a monitoring area. A screen acquisition member(212) is embedded to a computer, connected to the camera member and acquires a screen from the camera member according to a screen acquisition signal at every predetermined time period. A previous screen luminance storing member(214) stores the acquired screen according to a storing signal. A control member(216) supplies the screen acquisition signal to the screen acquisition member at every time period, calculates the distance between luminances relating to the pixels of the acquired screen and of the previous screen. Then the control member counts the pixel number when the distance exceeds a predetermined value and outputs the storing signal to the screen storing member when the counted pixel number exceeds a predetermined number.
