Adjusting webcam properties
You can adjust the following webcam properties:
●
Brightness—Controls the amount of light that is incorporated into the image. A higher brightness
setting creates a brighter image; a lower brightness setting creates a darker image.
●
Contrast—Controls the difference between lighter and darker areas on the image. A higher contrast
setting intensifies the image; a lower contrast setting maintains more of the original information’s
dynamic range but leads to a flatter image.
●
Hue—Controls the aspect of color that distinguishes it from another color (what makes a color red,
green, or blue). Hue is distinct from saturation, which measures the intensity of the hue.
●
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 Comp—Compensates in cases where a subject with a large amount of background light
would otherwise be obscured by blooming or silhouetting.
The Properties dialog box is accessible from various programs that use the integrated camera, usually
from a configuration, settings, or properties menu.
