Image Settings
1. JPEG Quality sets the desired qual-
ity when the JPEG image format
is selected. Selecting a higher
quality results in a higher quality
image, but a larger file.
2. Brightness allows you to set the
brightness level the imager will
use when taking images.
3. Edge Sharpness specifies how
much the imager will attempt to
sharpen edges in images it takes.
Selecting the highest position on
the slider gives the sharpest edges,
but also increases noise in the
image.
4. Gamma Correction measures the brightness of midtone values pro-
duced by the image. You can brighten or darken an image using
gamma correction. A higher gamma correction yields an overall
brighter image. The lower the setting, the darker the image. Move the
slider to change the amount of correction the imager applies when
taking images.

account your particular environment and conditions to determine optimal set-
tings for your specific situation.
