Camera test light box

Main uses:

The main purpose of the camera test light box is to provide a special lighting environment for the camera test, which meets the requirements of high illumination uniformity, light source color temperature can be switched, and illuminance can be adjusted continuously. Specifically, it helps testers evaluate the following performance of the camera:

Clarity and color reducibility: Under certain lighting conditions, testers can observe whether the image captured by the camera is clear and whether the color is accurately restored.

Illuminance and backlight compensation: By adjusting the illuminance of the light box, the tester can evaluate the performance of the camera in different lighting conditions, especially in the backlight environment can maintain the sharpness of the image and color accuracy.

Distortion and power consumption: During the test process, you can also observe whether the camera has problems such as image distortion, and measure its power consumption and minimum operating voltage and other parameters.

Applicable standards:

The design and use of camera test light boxes generally follow the following standards:

Light source color temperature: A variety of color temperature light sources are usually provided in the light box, such as D65（6500K） international standard artificial daylight, TL84（4000K） European, Japanese, Chinese store light sources, etc., to meet the needs of different test scenarios.

Illuminance range: The illuminance range is usually adjustable to suit the test needs of different cameras. For example, some light boxes have an illumination range of 750 to 3200 Luxes.

Lighting uniformity: Lighting uniformity is one of the important indicators to evaluate the performance of the light box. High quality light boxes usually have a light uniformity higher than 80% or even more than 90% to ensure the accuracy of the test results.

Timing function: In order to record the use time of each set of light sources, the light box is usually equipped with strong timing function, so that the tester can better manage and analyze the test data.

In addition, the camera test light box should also meet the standards and requirements of relevant institutions such as the International Institute of Lighting （CIE） to ensure the accuracy and reliability of its test results. At the same time, the design and manufacture of the light box should also follow the relevant safety standards and specifications to ensure the safety of the operator.
