Advanced
To optimize the lighting settings according to your requirements, modify the following
settings under Lighting Conditions:
• White balance - the white balancing system in the AXIS 231D can automatically
detect white in the image and intelligently use this as a reference for other colors.
• Exposure control - this setting is used to adapt to the amount/type of light being
used. Allow slow shutter can be enabled/disabled when the exposure control is
set to Automatic.
• Backlight compensation - this setting is used to make the subject appear clearer
against e.g. a bright background.
Image Formats Image Size
• Windows 24-bit BMP (full color)
• Windows 4-bit BMP (16 colors)
• OS/2 4-bit BMP (16 colors)
The height and width of the overlay image in
pixels must be exactly divisible by 4.
• If the image overlay and text overlay are larger than the video image, no overlay will be displayed. When also using a text
overlay, this will occupy 16 pixels in height and as many in width as the video image. Please consider this when configuring
the overlay image.
• If the overlay is initially positioned so that part of it is outside the video image, it will be relocated so that it appears over the
video image, i.e. the entire image is always displayed.
• The maximum overlay image size supported by the AXIS 231D is the same as the maximum image resolution. See Technical
Specifications, on page 46.
