Horizontal illuminance is the value measured when the illuminometer is placed horizontally above the field. The relevant data such as the maximum, minimum and average values of the illumination of the site are usually measured and calculated.
A high-speed football game that maintains a good illumination uniformity of the venue helps to improve the athlete's game status and produce high-quality video recordings.
The vertical illumination of the field camera, the vertical illumination refers to the vertical illumination of the athlete. Vertical illumination helps capture the momentary movements in motion during the game, especially facial expressions. These pictures are captured by the field camera. A large change in vertical illumination will result in poor digital video quality. Designers must consider the illuminance balance in all directions to reduce the illuminance imbalance when shooting on the field camera.
The vertical illumination on the field captured by the edge and the bottom camera of the goal is categorized by the vertical illumination of the fixed camera. These camera lenses must cover the entire game during the game. Too much variation in vertical illumination will result in poor digital video quality. Designers must consider the illumination balance in all directions to reduce the imbalance of illumination when shooting on fixed cameras.
The color temperature is a feeling or phenomenon that describes the warm (red) or cold (blue) illuminance. The unit is Kelvin (Tk). Digital camera technology in front of the door, the camera can mediate according to the actual color temperature and contrast. Get the desired ideal color quality. For outdoor stadiums of all competition levels, Tk ≥ 4000 can meet the demand.
The color rendering index is the ability of an artificial illumination source to mimic natural light. In fact, the color rendering index range is required to be Ra20~Ra100. The higher the color rendering index, the better the light color.
