slower computers. When the “optimized for speed” option is selected, the image
quality is noticeably poorer, but CPU usage is minimized and frame rates are
always at their maximum. This setting does not affect how images are captured.
Captured images always use the highest quality algorithms to process the raw
data from the camera into full color images.
3.6.3 Preview Zoom Level
The preview window can be set to “Actual Size (100%)”, which will display the full
field of view at its actual size. Selecting “Half Size (50%)” will shrink the display
50% in each direction while maintaining the full field of view. This option is useful
when previewing large resolutions that are larger than the monitor’s display size.
3.6.4 Generate Flat Field Correction
Flat Field Correction is used to correct for uneven lighting and other fixed pattern
non-uniformity in the image. This action is used to generate the correction to be
applied to the image. Before selecting it, you should make all your imaging
adjustments (exposure, gain, etc.) and then remove any sample from the field of
view so that you only have an empty “background” image. Once the correction is
generated, it can be applied using the next action.
3.6.5 Enable Flat Field Correction
This action applies the flat field correction that was generated in the previous
action. When enabled, the correction will be automatically applied to both the
live preview and the captured image. If you change the resolution of the preview,
the correction will be reset and disabled. If you change the field of view, by
selecting a different objective lens, for example, you should re-generate the
correction for the new field of view.
3.6.6 Image Flipping
Image flipping (vertical) and mirroring (horizontal) are available from the Options
drop down menu or the left-right, up-down arrow icons on the toolbar. Selecting
these options will flip the preview image 180° either vertically or horizontally.
This option also affects the captured image.
3.6.7 Multiple Image Averaging
This feature is accessed through the Options drop down menu. Image averaging
is an effective tool to reduce random noise in your images. To enable this
feature, you select the Multiple Image Averaging option from the Options Menu.
You can change the number of images that are averaged together using the
Multiple Image Settings Dialog, which is accessed by selecting the Multiple
Image Settings option in the Options menu.
