USER1 These are two user-definable setting that let you control red and
USER2 blue gain. This can be useful in environments that are saturated
with a single colour of light (for example bars or entertainment
venues), or it can help vision-impaired (colour-blind) users.
ANTI CR Anti colour rolling. Some types of lighting can cause colour bars
rolling over the screen. Use this setting to compensate.
MANUAL When you switch the camera on, it will acquire a white balance
value from the whitest object in view. The camera will then
reproduce white colour based on this value, regardless of
changes in colour temperature or other factors. If this value
gives insufficient colour quality, you can manually adjust the
balance between red and blue levels to improve the image.
PUSH Use this option to adjust white balance based on a white object
LOCK that you use as a baseline. Point the camera at the white object
and make sure it fills as much of the screen as possible. Click the
middle button on the joystick. The camera will now use the
colour of that white object as a baseline.
7.4 Back light
If there is a bright light in the background, for example from a window, the
image around it may be too dim to see clearly. In that case, use the
backlight function to compensate.
Display: BACKLIGHT
OFF No backlight compensation
BLC Back light compensation. The camera automatically brightens the
dim parts of the image.
HLC Highlight compensation. Use this setting to compensate for extreme
differences between dark and light areas. For example, if someone
shines a bright light directly into the lens, the entire image can
become overexposed. With HLC, the camera masks the bright area
so that the area around the light source is still visible.
7.5 Picture adjustment
These are the common adjustments for video images: MIRROR to mirror
the image, BRIGHTNESS (brightness), CONTRAST (contrast),
SHARPNESS (sharpness), HUE (hue), and GAIN (gain).
7.6 ATR
Use the Adaptive Tone Reproduction (ATR) function to improve the colour
tones of subjects in images that contain both bright and dim areas (for
example, a wall with a window).
