Figure A2-10: Settings used in Figure A2-8
Example A2-3(Indoor Situation 2)
Figure A211 is the original picture; the sunlight spreads
out through the window. Due to the auto-iris
adjustment of camera, the interior of the house is
underexposed and many objects cannot be identified
clearly, especially the advertisement paper at the lower
half part of the image.
Figure A2-12 : Visibility Enhancement was applied to
the whole picture. The advertisement paper at the lower
half part of the image is more visible, but both the left
and right sides of the window are overexposed.
Figure A2-13 : You can mask out the
upper half part of the picture to apply
Visibility Enhancement for the lower
half part. The advertisement paper is
clearer and the other part appears the
same as in the original video.
