Video conference camera parameter analysis
White balance:
The white balance control of the video conference camera is to allow the white objects in the actual environment to appear as "true" white in the picture you shot. Different types of light sources will produce different color tendencies in the picture. For example, the light of a candle will make the picture orange yellow, and the light after dusk will put a cool blue tone on the scenery. Our vision system automatically compensates for different lights, so we look for a white sheet of paper to be white forever, whether in warm or cool lighting. But the camera is not the case. It will only directly record the colors presented in front of it, which will lead to a warmer or cooler picture.
Minimum illumination:
Because there are no international standards for management, each large CCD manufacturer has its own method of measuring CCD sensitivity. However, a camera labeled (1Lux, F10) can be exactly the same as the camera labeled (0.01 Lux, F10)!
Shutter speed:
The shutter speed is an important parameter for the camera shutter of a video conference camera. The shutter speeds of different models of cameras are completely different. Therefore, when using a certain model of camera to shoot a scene, be sure to first understand the shutter speed, because When you press the shutter, only the start time of the shutter is taken into account, and the release timing of the shutter is mastered to capture a vivid picture.
