Abstract: A method performed by a processor comprises determining a depth value of a target area relative to the image capturing device. The method also includes determining an adjustment to the brightness control so that a brightness level of images captured by the image capturing device is lowered if the depth value of the target area relative to the image capturing device is less than a threshold depth value.

If the adjustment of the brightness control is to be manually adjusted, the processor over-rides manual control of the brightness control if an operator of the brightness control is causing the brightness level of images not to be lowered if the depth value of the target area relative to the image capturing device is less than the threshold depth value.
