Supports ARIA1 Camera Feature

ARIA (Automatic Restoration of Illumination Attenuation) adjusts illumination so that light is more evenly distributed between the wide and the telephoto ends of the lens. First, the Camera-lens communication at initialization identifies the lens attached. When zooming, the camera’s gain is increased starting at the F-drop/ramping point. Simultaneously, Peripheral Illumination Correction corrects light fall-off from the center of the frame to the periphery, This correction more evenly distributes light throughout the entire image.
