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.
