The wide dynamic camera technology is a technique that allows the camera to see the characteristics of the image under very strong contrast. In some cases where the contrast between light and shade is too large, the general camera is limited due to the CCD's photosensitivity, and the captured image tends to be too bright or the foreground is too dark. In response to this situation, wide dynamic technology came into being and solved this problem better.
Test <br> <br> test methods may vary dynamic range of the camera, but the test principle is similar, Here are a basic test method JVC follows:
The equipment and conditions required to test the dynamic range of the camera The following equipment is required to test the dynamic range of the camera:
Transmission gray card and reflection gray card;
·Brightness adjustable backlight light box and adjustable illumination light source;
Video monitor and waveform monitor;
Light meter or illuminometer;
· Standard internal lens and so on.
Conditions for testing the dynamic range of the camera: It is necessary to perform in a dark room.
application
Highway toll system :
At present, the focus of low-light and wide-dynamic cameras for road monitoring is the highway toll monitoring system, which is mainly for the charging lanes, toll plazas, and toll booths, the type of vehicles that the toll lanes pass through, and the operation process of the toll collectors. As well as emergency and special events during the charging process, observations and records are made and effective supervision is implemented. . Especially at night, toll booth staff need to see the license plate. Under normal circumstances, after the lights are turned on, the ambient illumination and the license plate illumination on the road form a certain dynamic range. Traditional cameras are difficult to “seeâ€, so they are low. Illumination, wide dynamic cameras have a demand.
electronic system
Through closed-circuit television monitoring and automatic red-light recording, the command center has improved its intuitiveness, real-time mobility, and response to accidents and accidents, as well as enhanced objectivity in investigation and handling of violations, and has fully coordinated control areas. Control to improve the vehicle's capacity. Due to the need to see the license plate, 24-hour monitoring, so there is a demand for low illumination, wide dynamic cameras.
City Commercial Street
There are also certain applications in the city commercial street to grasp the traffic conditions of some bustling intersections, the operation of the vehicles around the road sections, the traffic situation of pedestrians, and the traffic security situation.
