• Manual Exposure: Captures one (or more) images with
a pre-selected exposure time.
• Auto Exposure: Captures an image with an ideal
exposure time determined automatically by the system
prior to image capture. (NOTE: When using the Auto
Exposure function, any exposure time settings made by
the user prior to image capture will be changed.)
After selecting Auto Exposure, select from one of the
following image acquisition settings:
1. Best (Longer Exposure) exposes the image to the
maximum value of the histogram (65,000 gray
levels).
2. Better exposes to fill the histogram 50% so the
brightest portion of the image is at 32,000 gray
levels.
3. Good exposes to fill the histogram to 25% or 16,000
gray levels.
4. Minimum (Fast Exposure) exposes to fill the
histogram to 10% over background. Minimum and
Good settings are particularly useful for
chemiluminescent imaging applications and allow for
quicker image capture overall.
• Sequential – Constant Time: Select the number of
frames to be captured as well as the total image capture
time, and the software will automatically capture the
desired number of frames with evenly divided exposure
times.
• Sequential – Variable Time: Captures sequential
images with user-selectable exposure times per image.
For example, capture one image at 300ms exposure,
immediately followed by another image captured at
200ms exposure, and so forth.
Click “+” to add a new interval. Tap to edit each time
block (Min, Sec, Ms and Micro) as needed, then use the
on-screen keyboard to make edits. Or, use the
dropdown menu to select from several pre-defined
interval sets for specific applications.
• Image Integration – Continuous: Captures multiple
images at a desired exposure time and continually
“stacks” the images, compensating for low-light
limitations. Image Integration - Continuous will continue
image acquisition and “stacking” until the user stops the
image capture.
• Image Integration – Automatic: Similar to Image
Integration - Continuous, except the software
automatically stops image capture and “stacking” when
the ideal level of saturation has been achieved.
Select the Number of Frames to be captured during
Manual Exposure and Sequential – Constant Time image
capture modes. Use the “+” and “–” buttons to select the
desired number of frames.
