Usage tips
Reading aloud – Text blocks
Reading aloud is best done in a reading mode where you easily can select the text blocks.
Reading aloud – Recognition
Text recognition isn't 100% accurate. The devices will make mistakes. By changing the magnification you
can adapt the quality of recognition.
Reading
Reading is best done in positive or negative mode. These modes adapt the image for the visually impaired
to a high-contrast image with improved background. Background and letters can be set at your discretion.
The background can be set by means of background suppression. This will allow you to filter out the
structure of a sheet. This unique KOBA Vision function allows you at all times to set a contrasty background
without annoying paper impurities. A newspaper can be read without annoying paper impurities. Factory
settings will take you back to the original settings.
Watch photos
Photos are best watched in photo mode. This mode is a unprocessed image without contrast
enhancement. Using the buttons contrast, brightness and colour, you can adjust the image so that the
photo becomes clearly visible. Factory settings will take you back to the original settings.
Crafting
Crafting is best done with a small enlargement. It is better to select a dark background during this activity
so that the camera is not hindered by large differences in contrast with whatever is darkened by the hands.
Writing
You can also write under your video magnifier. It is best to use a black pen and lined paper.
