FUNCTIONS

Gamma

Used for setting gamma compensation to OFF, ON (1), or ON (2).

OFF	: Outputs CCD signals for image processing linearly.
ON (1)	: For obtaining natural gradation taking into account the characteristics of the monitor.
ON (2)	: For obtaining three-dimensional images with a subject that has a small luminance dynamic range.

Concept of Gamma Characteristics

Sharpness

Used for adjusting sharpness of the image.

The sharpness can be changed by about more than 200% from the factory setting.

White Balance

Used for adjusting white balance by adjusting R-gain and B-gain. White subjects can be shot in white by setting the white balance according to the color temperature of the luminance light. The White Balance operation mode can be selected from three modes – Manual, One Push, and ATW. The range of operations of each mode is as follows.

Manual	: 2,400 to 10,000	K or more
One Push : 2,400 to 10,000		K or more
ATW	: 2,650 to 6,000 K or more (Excluding fluorescent light)

Color Temperature

This function was originally intended for selecting the optical filter. However with the DFW-SX900/X700, the R-gain and B- gain are set to the appropriate White Balance when color temperatures 3,200 K and 5,600 K light sources are used.

Hue

Used for adjusting the hue of the image.

The hue can be changed by about more than ±15 degrees from the rotary angle of the NTSC Vector Scope luminance scope based on the factory setting.
