TRAFFIC ENFORCEMENT SYSTEM WITH TIME TRACKING AND INTEGRATED VIDEO CAPTURE
First Claim
1. A method for operating a traffic enforcement system device, the method comprising:
- determining a distance to a moving target vehicle;
focusing a camera on said target vehicle based on said determined distance;
zooming said camera in on said target vehicle such that an image of said target vehicle substantially fills a field of view of a display of said camera;
periodically redetermining said distance to said moving target vehicle to maintain said image of said target substantially within said field of view of said camera;
determining target data for said moving target vehicle;
displaying said target data on said camera display;
capturing one or more images of said target vehicle; and
storing said one or more images and corresponding target data of said target vehicle.

Abstract
A method, system, and apparatus are provided for capturing a video image and speed of a target vehicle. A ranging device detects a distance to a target vehicle. The focal distance or zoom of a video camera is set and adjusted based on the distance. The speed of travel of the vehicle is detected, displayed, and/or stored in association with a video image captured of the vehicle by the video camera. A range of distances within which to capture the video image and speed of the vehicle may be set by detecting distances between a pair of landmarks or using GPS and compass heading data. An inclinometer is provided to aid initiation of a power-conservation mode. A target tracking time may be determined and compared to a minimum tracking time period. A device certification period can be stored and displayed and the device deactivated upon expiration thereof.

21. A traffic enforcement system device comprising:
-
a detection module that determines one or more of a distance to a moving target vehicle and target data for said moving target vehicle, the detection module periodically redetermining one or more of said distance to said moving target vehicle and said target data; a display device; a camera configured to capture one or more images of said target vehicle, the focal distance of said camera being set based at least partially on said determined distance such that an image of said target vehicle substantially fills a field of view of the display device, the focal distance being periodically adjusted based on the redetermined one or more of said distance to said moving target vehicle and said target data to maintain said target vehicle substantially within said field of view of said camera; a control module that displays said target data on said display device and stores said one or more images and corresponding target data of said target vehicle in a memory. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28)
