Lumenera Scientific Infinity Camera

When enabled, every time you capture an image the number of images you
selected will automatically be collected and averaged together.
This feature is not supported by the Infinity X when capturing high-resolution
(DeltaVU™) images.
3.6.8 Preview Histogram
A real-time intensity histogram can be overlaid on the preview window. This
histogram can be used as a guide to setting the image properties such that the
full dynamic range of the image sensor is being utilized. To display the preview
histogram, select Preview Histogram from the drop down Options Menu or select
the histogram icon from the toolbar.
3.6.9 Highlight Saturated Pixels
This option allows you to highlight the pixels in the image that are at or near
saturation. Saturation in this case refers to the brightness of the pixel. Starting
at a value of 240 (out of 255) the pixels will be changed to light red and as they
get closer to their saturated value of 255 will get progressively darker red. In the
case of a monochrome camera, the pixels will turn black, not red.
3.6.10 Load Overlay Bitmap
Any arbitrary bitmap can be overlaid on the live preview display or captured
image. A set of digital reticles is included with the application that can be used
for measurements or to aid object indexing and alignment.
Once the bitmap is loaded, you select from the Options Menu to overlay on the
preview image and/or the captured image.
You can also create your own bitmaps to overlay, using any paint program. The
bitmap must have a width that is evenly divisible by four and must be in RGB24
format, but other than that, there are no restrictions. Any part of the bitmap that
is pure white (RGB = 255, 255, 255) will be transparent with any other color
overlaying and replacing the image data.
If the bitmap is smaller than the image display resolution, the bitmap will be
placed in the upper left corner of the image. If either of the width or height of the
bitmap is larger than the image display resolution, the bitmap will be centered.
Currently, overlays are not supported for monochrome cameras.
3.6.11 Load Alpha Blending Bitmap
An alpha blending bitmap can be used whenever an overlay bitmap is being
used. This bitmap affects the way the overlay bitmap is actually overlaid. It is
often undesirable to have the bitmap completely obscure the image data. The
