What is AWB?

 AWB ( Auto White Balance). The human eyes always see the white light, but the image sensor (CCD, CMOS) in the camera will record the color temperature of the light source and restore the color to the image in. For example, with the tungsten bulb to illuminate the scene, then the image shooting out will be partially like orange tones. Therefore, in order to make the scene color display correctly, we will use the AWB function to make the original white color look more real.

What is BLC?

BLC (Back Light Compensation), automatically brings more detail to darker areas of an image when bright light shining from behind obscures it and provides perfect exposure for an object in front of very strong back light.
