PICTURE IMAGE STORING DEVICE OF SECURITY SYSTEM

摘要

PURPOSE: An image storage device is provided to improve reliability by processing image sensing function with hardware type in real time by storing image by compression from the time when any motion is sensed in a security area. CONSTITUTION: A picture image storing device of security system comprises: a digital camera(101) for imaging an image of body to be monitored and converting it to a digital signal; a motion sensor(105) for comparing a present image from the camera to a previous image to sense motion and outputting a motion sensed signal when a difference between these images is above a predetermined value; and a sensor part(108) for sensing change amount of motion, temperature, impact, humidity and voice in certain area and transmitting it to a CPU(central processing unit)(111). The CPU activates the digital camera when it senses change amount in the sensor part, and compresses an image from a sensed timing and stores the compressed images in a flash memory(112).
