3. Getting An Image
3A. Press the green arrow icon in the upper left-hand corner.
3B. This View window will appear on your
computer screen. It shows what the camera sees.
NOTE: The camera view is black and white
when the Usoria starts up. You will change
this in the next step, Advanced Color & Image
Settings.
To focus the camera, adjust the focus on your
camera lens.
If the view window is black, try the following:
•
•
•
•
•
•
Be sure the lens cap is off.
Check the lens to be sure it is properly connected to the camera.
Open the iris on the lens to allow more light into the lens to see the image.
Check the USB 2.0 cable to be sure it is properly connected to the camera.
Check the USB 2.0 cable to be sure it is properly connected to the USB 2.0 port on your
computer.
If none of the above work, you are in trouble!

4. Advanced Color and Image Settings
4A. Type Alt and S. Or, click on “Device”, then
“Settings”.
4A.
This Device Settings window will
appear.
4B. Select a Color Mode – Choose
Bilinear for general use.
Monochrome is black and white.
Nearest Color gives you the fastest
transport stream with the worst
image quality.
Bilinear gives you medium speed
and quality.
Laplacian gives the best image
quality with a slow transport
stream.
4B.
4C. The Flip Image controls will flip
4C.
the image horizontally (sideways)
and/or vertically (upside down). Leave
these unchecked.

4F.
4E.
4D. External Trigger Polarity: This option is for taking snapshots with an external trigger. “Positive”
enables the Trigger input #1, and Negative enables trigger input #2. For more information, see the
External Trigger Connector Pinout diagram in the User Guide.
4E. Additional Options:
Direct Access to Driver Frame Memory: For general use, leave this unchecked. For more information,
see the User Guide.
Check Enable Image Correction: This enables the controls for brightness, contrast (the difference
between light and dark areas of the image), and gamma (the overall brightness and hue).
Display Video on Program Startup: This option is not currently enabled.
4F. Median Filter: For general use, leave this unchecked. Use the Median Filter to reduce camera
“noise” – unwanted specks in your camera image. It can also be used to smooth a sharp transition
between light and dark areas of the image. The Median Filter will slow the frame rate by about five to
seven percent.
4G. The Average Frames controls are used to increase the image quality of still pictures. For more
information, see the User Guide.
4H. Press the Close button to close the Device Settings window.

5. Adjusting the Area Viewed by the Camera
The viewport is the rectangular area where the image seen by the camera lens is scanned. The smaller the
viewport size, the higher the frame rate for your video. For general use, you will want a larger Viewport
so that you can see more of your image. However, when the frame rate is important, select a smaller
Viewport.
5A. To open Viewport Settings, press Alt and V, or
press “Settings” under “Viewport” on the main
menu.
5A.
This window called “Viewport Settings” will
appear. The blue shaded rectangle in the center
represents the size of the current Viewport area
compared to the size of the total possible
Viewport area.
5B. To change the viewport size, check one of
the buttons on the “Predefined” control. For
general use, a larger Viewport setting is best.
5B.
When you change the viewport size, you may
need to provide more light to the camera lens.
Adjust the exposure control slider upward, or
open the iris on the lens.
Page 7
5C. To capture just one section of the total
view, click on the blue shaded rectangle with
the left mouse button and drag it to the area
you want to view. (Drag to the right to see
an area on the right, and drag to the left to
see an area on the left.) The changes are
displayed in the View window immediately.
5C.
These pictures below show how capturing different sections of the Viewport Settings will give you
different views. Here, the Viewport setting shows the largest area possible.
In this example, the Viewport Setting shows just a small area of the total view. For this picture, the
Exposure slider was adjusted upward to allow more light into the lens.
Page 8
5D. As you change your Viewport settings, your frame rate will be displayed in the far right corner of the
main menu. In this example, the smallest View window size will give you a frame rate of 62 fps, or 62
frames per second.
5D.
5D.
For information on manually setting the Viewport size with the “Offset” controls, please see the User
Guide.

6. Calibrating for the Right Colors
To calibrate for the correct colors, set the “White Balance”. “White Balance” tells the camera how to
calculate the difference between white and other colors.
Always set the white balance when you start to use your camera, or whenever your lighting conditions
change.
To set the white balance, the camera must be on.
6A. If the camera is off, press the green arrow icon in the upper left-hand corner.
6B. This View window will appear on your computer
screen. To focus the camera, adjust the focus on your
camera lens.
Point the camera lens at a large white object, such as
a piece of blank white paper. Cover the whole field
of view and use good lighting.
Under Sensor Control use the Exposure slider to
adjust the exposure time.
6C. Type “W” to set the white balance. Or,
select “Color Balance”, then “White Balance”.
The image in the View window will
immediately have more realistic colors.
6C.
6C.

6C.
6D.
6C. Another way to set the White Balance is to
click on “Device”, then “White Balance”.
6D. If your image is not bright enough, use White
Balance (Gain). Type “Alt” and “W” at the same
time, or select “Device”, then “White Balance
(Gain)”.
Re-adjust the Exposure and Gain controls if
needed. If the image is too dark, adjust the
Exposure slider upward. If it is too light, move the
Exposure slider downward. Your settings will be
saved automatically.
Page 11
6E. To un-do the White Balance, select “Default”.

7. Where and How to Store Videos and Pictures on Your
Computer
In the Capture Options section, you can select where to store your videos and pictures on your computer.
7A. For Capture Options, press Alt and C, or select
File, then Capture Options.
7A.
This Capture Options window will be displayed.
7B. In the Picture File Store Folder box, press the file
folder icon.
Select the computer “folder” where you would like
to store your videos or snapshots.
7B.
7C.
7C. File Name Prefixes are set automatically by
combining a file name prefix and the number of the
last captured file plus one. For example, if the last
captured video file is “FRAME_15.bmp”, the next
file will be named “FRAME_16.bmp”. If you prefer,
you can change the file name prefixes.
You can also change single file names. Open the file folder on your computer where the files are stored,
right click on the file and select “Rename”.
For information on “Limits” and sequence counts, please see Section 9 of this Quickstart Guide,
Shooting Frames or Frame Sequences.

8E.
8D.
8A. Press the Green Button to start the Video mode.
8B. Set the camera settings as desired -- exposure, gain, viewport, etc.
8C. To shoot video and save it to a file on your computer, press F4 or the video camera button.
8D. To stop shooting video, press Esc or the red Stop Video button.
8E. To capture a single frame of a video, press F2 or the plain camera icon.

9. Shooting Frames or Frame Sequences
To shoot a frame sequence, bring up the Capture
Options screen.
9A. Press Alt and C, or select File, then Capture
Options.
9A.
9B.
9C.
9B. Check “Limit Sequence Count” and enter the number of frames you want to shoot in sequence.
(This number must be higher than one.)
9C. Enter a number for the timing of your frame sequence. A millisecond (ms) is 1/100th of a second. If
you set “Capture a frame every” to 100, you will take one picture every 100 milliseconds.
Page 15
9. Shooting Frames or Frame Sequences -- Continued
For example, if you set “Limit Sequence Count” to six frames and set “Capture a frame” to every 100
milliseconds, you will take six pictures at the speed of one picture every 100 milliseconds, or six pictures
at the speed of one picture every tenth second.
The millisecond interval where you capture a frame must be more than the current frame Exposure that
was set with the Exposure slider on the main menu. For example, if your Exposure is 59, you must
capture a frame at least every 60th millisecond. If it is less, an error message will display and you will
need to change either the exposure time or the number of frames.
For information on capturing frames as an average of frames, see the User Guide.
9D. To shoot a frame sequence, press F3, or the camera icon with the yellow plus sign.
9D.
The frame sequence will be saved as a bitmap file.

trigger” attached to your camera. For more
information, please see the User Guide.
