Monitoring system-white balance

White balance, that is, White Balance. The color of the object will change due to the color of the projected light, and the images taken in different light situations will have different color temperatures. For example, a photo taken in an environment illuminated by a tungsten filament lamp (electric bulb) may be yellowish. Generally speaking, there is no way for a CCD to automatically correct light changes like the human eye. Therefore, through the correction of white balance, it will immediately adjust the intensity of the red, green and blue colors of the entire image according to the characteristics of the image in the current portrait to correct the errors caused by external light. In addition to the automatic white balance or specific color temperature white balance function, some cameras also provide manual white balance adjustment.
