MULTIPLE RESOLUTION CAMERA SYSTEM FOR AUTOMATED LICENSE PLATE RECOGNITION AND EVENT RECORDING

摘要

An in-car multiple-resolution camera system for first responder vehicles includes a high-resolution camera imager for capturing images in high resolution and outputting the same in a first high-resolution image output stream. A signal processing module is provided for processing the first high-resolution image output stream and producing (1) a reduced-area high-resolution image output stream containing image information for only a selected portion or portions of the original image and (2) a wide-area low-resolution image output stream. The wide-area low-resolution image output stream can represent the the full image, if desired. An event recorder is provided for recording the events imaged by the camera imager using the wide-image low-resolution image output stream. A license plate recognition system is provided for using the reduced-area high-resolution image output stream to capture and process images of vehicle license plates nearby.
