MULTIPLE CAMERA IMAGE MULTIPLEXER

摘要

The multiple image video surveillance camera system that uses a common set o f sequencing logic to sample multiple imaging devices or multiple pre-set imag e windows within a large high-resolution imaging device is provided (32, 34 of fig. 2). The images are multiplexed into a single frame or switched on a fra me- by-frame basis at the imaging device. The switched frames are marked or encoded (36 of fig. 2) to facilitate separation for individual image display . This configuration allows one camera processor or sequencer to support multiple imagers and eliminates the need for a separate multiplexer, which lowers the system cost. Using a single transmission media (36 of fig. 2) to the video recording or display devices significantly reduces system installation cost.
