Divide a scanned image with the reference image that expresses changes of dark and
bright as a whole, and correct the brightness throughout the image.
{
(Each gray level of scanned image) X reference gray level} / (Each gray level of
reference image)
- Divide a scanned image that is shot under the uneven light by a blank image that is
shot under the same light condition, you can change the image to the one that is shot
under the even light.
Subtract a scanned image with the reference image that expresses changes of dark
and bright as a whole, and correct the brightness throughout the image.
{
(Each gray level of scanned image) + reference gray level} - (Each gray level of
reference image)
- Subtract a scanned image that is shot under the uneven light by a blank image that
is shot under the same light condition, you can change the image to the one that is
shot under the even light.
Filter a scanned image with the maximum value, and then with an average value, to
make a brightness image.
[Max. value filter: Max. gray level of 3 x 3]
-
[Average value filter: Average gray level of 3 x 3]
- Use this filter when a brightness distribution image (reference image) for the
scanned image cannot be obtained.
