Image Settings allows you to set the following items:
NOTE
The setting items vary depending on whether Select Source is Platen or film.

When this is set to ON, the outline of the subjects is emphasized to sharpen the image.
Printed photos and pictures are displayed as a collection of fine dots. "Moire" is a phenomenon where uneven gradation or a stripe pattern appears when such photos or pictures printed with fine dots are scanned. Descreen is the function for reducing this moire effect.
NOTE

IMPORTANT
- Do not place items that weigh 4.4 lbs (2.0 kg) or more on the Platen. Also, do not press on the document with a force exceeding 4.4 lbs (2.0 kg). If you press heavily, the scanner may not work correctly or you might break the glass.
- Align the document with the edge of the Platen. If not, the shadow will not be corrected properly.
- Shadows may not be corrected properly depending on the document. If the page background is not white, shadows may not be detected correctly or may not be detected at all.
- While scanning, press down on the spine with the same amount of pressure you used to preview the scan. If the binding part is not even, the shadow will not be corrected properly.
How to place the document depends on your model and the document to be scanned.
NOTE
- Cover the document with black cloth if white spots, streaks, or colored patterns appear in scan results due to ambient light entering between the document and the Platen.
- If the shadow is not corrected properly, adjust the cropping frame on the preview image.
- Manual Exposure
This function enables you to adjust the exposure data according to the film.
When this checkbox is not selected, the optimal exposure data (the exposure level for each RGB channel and compensation levels) is automatically set according to the color density of the portion within the cropping area of the film.
Select this checkbox if you intend to adjust the image using an application after it is scanned or to scan with an under-exposed or over-exposed effect.
After you select this checkbox, you can adjust the exposure in 1% increments within the range of 50% to 200%.
IMPORTANT
This setting is not available when Apply the tone value to all frames / Apply the tone value to all crops is applied.
NOTE
- Manual Exposure is not available in Basic Mode. To change exposure, select the Manual Exposure checkbox in Advanced Mode tab, then adjust the value and scan.
- When this checkbox is not selected, the time required for scanning varies by film since the exposure is automatically optimized according to the film.
- Apply the tone value to all frames / Apply the tone value to all crops
"All frames" is displayed in thumbnail view, and "All crops" is displayed in whole image view.
Click Apply to reflect the color adjustment data of the selected film frame or the portion within the selected cropping frame into other frames. This color adjustment data will be used in subsequent scans. It will remain in effect until you click Reset.
This is useful when you want to scan film of photos taken on the same day in the same place, in a consistent color tone.
- High Quality
Set to ON to improve the image quality and reduce noise when scanning film.
IMPORTANT
- Image quality may not change depending on the film type.
- This setting is not available when Apply the tone value to all frames / Apply the tone value to all crops is applied.
