● Saturation—Controls the strength of color in the final image. A higher saturation setting creates a
bolder image; a lower saturation setting creates a more subtle image.
● Sharpness—Controls the definition of edges in an image. A higher sharpness setting creates a
more defined image; a lower sharpness setting creates a softer image.
● Gamma—Controls the contrast affecting the mid-level grays or midtones of an image. Adjusting
the gamma of an image allows you to change the brightness values of the middle range of gray
tones without dramatically altering the shadows and highlights. A lower gamma setting makes
grays look black, and makes dark colors even darker.
● Backlight Compensation—Compensates in cases where a subject with a large amount of
background light would otherwise be obscured by blooming or silhouetting.
● NightMode—Compensates for low-light conditions.
● Zoom (select models only)—Adjusts the zoom percentage for taking photos or recording videos.
● Horizontal or vertical—Rotates the image horizontally or vertically.
● 50Hz or 60Hz—Adjusts the shutter speed to achieve a video recording that does not flicker.
Customizable preset profiles for multiple lighting conditions compensate for the following lighting
conditions: incandescent, fluorescent, halogen, sunny, cloudy, night.
