How do I change the camera mode for the objective camera from standard definition (SD) to high definition (HD)?
Generally, you make camera mode setting changes in the Device Settings dialog. There are only a few steps required to change the camera mode from SD to HD.
Changing the objective camera mode is done in the Device Settings for each uScope individually.
The Device Settings dialog appears for the selected uScope.
The SD camera mode is a 960x540 image that is binned from a 1920x1080 image (each 2x2 pixel array is converted into a single pixel. One advantage of SD mode is that images are smaller and are transmitted to the PC much faster. Another advantage is that image noise (which all image sensors have) is significantly reduced.
The HD camera mode is a 1920x1080 image. An advantage of the 1920x1080 image is that it has double the resolution of the SD image. A disadvantage is that images are approximately four times larger and take more time to read/write to disk.
In order for the camera mode changes to become the new default, you must select the Make this the default resolution for this camera checkbox.
If you fail to select this checkbox, your changes to the camera mode will not become effective.
Whenever you change camera modes, it is always a good idea to re-calibrate the camera. Calibration resets the image exposure and color settings (white-balance). Additionally, a new flat-field image is captured to use with the flat-field filter applied to each scanned image.
Refer to the following knowledge base article to learn more about recalibrating the objective camera.
Finally, you must click Save and Exit to save the changes to the camera mode.
As of uScope Navigator v4.5, the Overview Camera mode is fixed to High-Definition mode and cannot be changed.
