Usage tips
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.
Readhelp
This readhelp is extremely useful for visually impaired people suffering from tunnel vision. The
readhelp consists of a reading line and a reading bar. This help allows a horizontal line or bar
to appear. This will keep you from confusing lines in the text (vertical confusion). The reading
line can be set to take on different colours. It is adviseable to select a line with a colour that is
different from the text. The read help can only be activated in the negative and positive
reading mode.
Factory settings
The factory settings button was especially provided to be able to return to the original settings
at all times. This means that you can always return to the original settings after having
adjusted contrast, background, colour, brightness, zoom, etc.
