Backlight; Picture Adjustment - Velleman CAMCOLD 23 Notice D'emploi

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
LOCK object 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).
Note: ATR can introduce noise in night-time images.
