Abstract: PURPOSE: A QUAD-display system is provided to perform a function of a memory controller in software by using a FIFO(First In First Out) memory and a signal processing device. The system can be used in a security and supervisory system using a black and white camera. CONSTITUTION: The QUAD-display system includes following units. The first converter(31) converts an image signal inputted through the respective supervisory black and white camera into digital image data. The first FIFO memory unit(32) stores sequentially the image data from the first converter(31). A signal processing unit(33) controls discrimination, storage and output of the image data from the first FIFO memory unit(32). A memory module(34) stores the image data inputted by the control of the signal processing unit(33). The second FIFO memory unit(35) stores sequentially the image data stored to the memory module(34) by the control of the signal processing unit(33). The second converter(36) converts the image data output from the second FIFO memory unit(35) into an analog image signal. A timing generating module(37) performs an interfacing function between the signal processing unit(33) and the first and second FIFO memory units(32,35).
