Auto Function Profile#

The Auto Function Profile camera feature allows you to specify how gain and exposure time are balanced when the camera is making automatic adjustments.

Using the Feature#

Setting the Auto Function Profile#

To set the auto function profile:

  1. Set the Gain Auto auto function and the Exposure Auto auto function to Continuous.
  2. Set the AutoFunctionProfile parameter to one of the following values (if available):

Available Auto Function Profiles#

Minimize Gain (= Gain Minimum)#

The gain is kept as low as possible during the automatic adjustment process. If the exposure time is at its upper limit and the target brightness value has not been reached yet, the gain will be increased in order to reach the target.

Minimize Exposure Time (= Exposure Minimum)#

The exposure time is kept as low as possible during the automatic adjustment process. If the gain is at its upper limit and the target brightness value has not been reached yet, the exposure time will be increased in order to reach the target.

Minimize Gain Quick (= Gain Minimum Quick)#

This profile works the same as the Minimize Gain profile. The difference is that it reacts more quickly in situations with extreme changes in brightness or where the image brightness changes rapidly. This situation occurs, for example, when microscope objective lenses are changed using the objective turret.

Minimize Exposure Time Quick (= Exposure Minimum Quick)#

This profile works the same as the Minimize Exposure Time profile. The difference is that it reacts more quickly in situations with extreme changes in brightness or where the image brightness changes rapidly. This situation occurs, for example, when microscope objective lenses are changed using the objective turret.

Smart#

Gain is kept as low as possible and the frame rate will be kept as high as possible during automatic adjustments.

This is a four-step process:

  1. The camera adjusts the exposure time to achieve the target brightness value.
  2. If the exposure time must be increased to achieve the target brightness value, the camera does so until the frame rate drops.
  3. If the frame rate drops, the camera stops increasing the exposure time and increases the gain until the AutoGainRawUpperLimit value is reached.
  4. When the AutoGainRawUpperLimit value has been reached, the camera stops increasing the gain and increases the exposure time until the target brightness value is reached. Increasing the exposure time results in a lower frame rate.

Anti-Flicker 50 Hz / 60 Hz#

Gain and exposure time are optimized to reduce flickering. If the camera is operating in an environment where the lighting flickers at a 50-Hz or a 60-Hz rate, the flickering lights can cause significant changes in brightness from image to image. Enabling the anti-flicker profile may reduce the effect of the flickering in the captured images.

Choose the frequency (50 Hz or 60 Hz) according your local power line frequency (e.g., North America: 60 Hz, Europe: 50 Hz).
