Value Description

PLL adjustment Changing the value adjusts the horizontal resolution of the image. Adjust the

value using small increments until the image is sharper. The value ranges from 0-

999 to 999.

Offset The Offset and Gain parameters function as contrast control for an image. The

Offset controls the darker parts of the image and the gain controls the bright

parts of the image. Adjust both values to optimize image quality. Adjust the

values using small increments until the image is sharper. If you set Offset to a

high value, set a high value for the gain to balance the two.

Gain The Gain and Offset parameters function as contrast control for an image. The

Gain controls the bright parts of the image and Offset controls the darker parts

of the image. Adjust both values to optimize image quality. Adjust the values

using small increments until the image is sharper. If you set Offset to a high

value, set a high value for the Gain to balance the two.

Aspect Ratio Sets the aspect ratio of the captured image. The default is 4:3. Set the value to

Wide mode when capturing images that have a wide aspect ratio. Using the

incorrect setting causes the image to be distorted or stretched.

HSync threshold Adjust horizontal sync detection.

VSync threshold Adjust vertical sync detection.
