Webcams / DirectShow devices

Webcams and other DirectShow devices are configured on the fly when being triggered by VIOSO 6. The settings provided by each camera can differ, but the most important settings usually are similar in naming and purpose.

Please compare your camera setting and find at least these obligatory settings:

Resolution and Frame Rate Setting (Format):

Choose the highest resolution your webcam supports while maintaining a high frame rate. There's often a dedicated best match like "FullHD @30Hz" that you should choose. The video type (compression, etc.) is neglectable.

This camera (a Logitech C930e) has a best match of resultion and framerate when using 1920x1080 @30 fps

Image Settings (Options):

After selecting the image formar, access the options to tweak the camera image by pressing the button "Options"

Exposure, Focus and Zoom Settings (Camera Contol):

Adjust the values for Exposure, Focus and Zoom (if enabled) manually to prevent overexposure or underexposure of the projected image as well as to get a focussed image.

Adjust at Exposure and other settings. Do NOT check "Auto"!

Deactivate Auto Exposure, Auto Focus and Auto Zoom by all means! All such automatic adjustments will mess up the scanning.

Find settings that provide a bright, but constrast-rich overall image

White Balance (Video Proc Amp):

Adjust the values for Exposure, Focus and Zoom (if enabled) manually to prevent overexposure or underexposure of the projected image as well as to get a focussed image.

Adjust the White Balance . Do NOT check "Auto"!

Deactivate Auto White Balance by all means! All such automatic adjustments will mess up the scanning.
