Quadrus MINI Imager User’s Manual
Camera Settings
Camera Settings
Camera parameters are typically obtained during the calibration process, and do not
necessarily need to be modified directly by the user.
Optics
The Quadrus MINI Imager has three different optical configurations available: Standard
Density, High Density, and Ultra High Density. Determine the optics of your imager and
find the corresponding camera values in the following sections.
Standard Density, High Density, and Ultra High Density Optics
Shutter Speed
Gain
Usage:
Faster shutter speeds reduce blurring in faster applications.
Slower shutter speeds are useful in slower applications and lower contrast
applications.
Definition:
This value sets the exposure or integration time for the image sensor pixels.
The shutter speed setting in relation to the speed of the object is critical. If a
slow shutter speed is selected to capture fast-moving objects, blurring or
smearing of the image will occur. As shutter speed is increased, more light
and gain become necessary, because the pixels’ exposure time has
decreased.

Default:

Options:
15 to 15,000
Usage:
Can be used to adjust the brightness of the image.
Definition:
Sets the gain value for the image sensor. This setting can be configured
through calibration, which is the recommended method. A higher gain
value will increase the brightness of the image, but the visual noise
reduction performance of the system is reduced. Before configuring gain
settings, the desired shutter speed should already be set and the gain
should be configured to optimize the shutter speed setting.
