camera settings
Select the Camera Settings Icon on the Future WinJoe toolbar. Brightness,
Contrast, Saturation, Sharpness, Gamma and White Balance can be
adjusted. (Figure 6). To return the camera settings to their default settings,
click the Default button.
Select the Camera Control tab to modify exposure times using exposure slider.
(Figure 7). To return the exposure to its default settings, click the Default button.
Try several different settings to get a feel of how the camera controls work
and affect the resultant image on the computer screen. The Brightness and
Exposure controls are the ones you will use the most.
The magnification, lighting conditions, and object being imaged will dictate
how these camera controls should be set. Usually Exposure will be set first
(higher magnification usually requires more exposure), and then Brightness is
adjusted as needed.
tips
loss of camera connection
If the computer connection to the camera is interrupted, you will need to
re-establish connection. This can happen due to several reasons; if a cable
becomes unplugged, the computer “freezes”, or the software/hardware other-
wise temporarily loses the data coming from the camera.
To re-establish camera connection, first close the Future WinJoe program on
your computer. Then, unplug and re-plug the camera into the computer’s USB
port. Now, open Future WinJoe, click the connect camera icon and the Live
Video Window should appear indicating re-established connection between
camera and computer.
On screen reticule
The on screen reticule can be switched on and off by clicking on the
reticule icon.
By calibrating the units of reticule against a ruler, target specimens can then be
visually measured against this reticule for precise measurement.
