Projecting White Documents; Adjusting Brightness And Image Contrast - Canon RE-455X Bedienungsanleitung

Projecting white documents

If the WHITE PAPER button is pressed when projecting text documents on a white background, this mode
automatically adjusts so projection of white parts of a document appear much whiter.
If the button is pressed, the WHITE PAPER indicator lights up.
If the button is pressed again, the indicator turns off and returns to
regular mode.
The effectiveness may vary depending on the document, including how dark it is.

Adjusting Brightness and Image Contrast

If you want to project a black or dark document, or the item being projected is small and has great contrast
compared to the background, you may be able to control the brightness (adjust the exposure) by using the
EXPOSURE knob to make the image clearer.
If the background is white and the subject is dark, sometimes the quality of the image improves if you place
it on black paper when projecting it.
Turn the knob toward the HIGH side to brighten the image. Turn the
knob toward the LOW side to darken the image.
Use the DETAIL control to adjust image quality. Turn the control
toward the HARD side to emphasize the outline of an object. Turn
the control towards the SOFT side for a softer outline.
Brightness may not be adjusted effectively using the EXPOSURE
knob if the image is too dark.
