An imaging system comprises an image capturing device, a viewer, a control element, and a processor. The control element controls or adjusts an image characteristic of one of the image capturing device and the viewer. The processor is programmed to determine a depth value relative to the image capturing device, determine a desirable adjustment to the control element by using the determined depth value, and control adjustment of the control element to assist manual adjustment of the control element to the desirable adjustment. The processor may also be programmed to determine whether the adjustment of the control element is to be automatically or manually adjusted and control adjustment of the control element automatically to the desirable adjustment if the control element is to be automatically adjusted.
