Explanation of Picture Quality
Adjustment Parameters
Picture quality variations when the R, G,
and B parameters are changed
CYN-RED adjustment (R parameter)
You can adjust the cyan and red color components. The
default is 0.
Pressing
B on the control button of the camera changes
the value in the plus direction to 1, 2 … 7, making the
red component value in the picture increase in the linear
direction that the brightness increases as shown in figure
1. This adds more red as if a red light has been cast.
However, the maximum effective brightness value is
255. When the value becomes larger than 255, saturation
occurs. When this occurs, the saturated white area
remains white even if the value is increased further in the
plus direction.
Pressing
b on the control button changes the value in the
minus direction to –1, –2 … –7, making the red
component value in the picture decrease in the linear
direction that the brightness decreases as shown in the
figure. Decreasing the brightness makes the red color
darker and reduces the redness. The complementary
color cyan (light blue) is added. In this case, the white
area becomes bluish.
