Specifying Settings for Documents and Color Mode

Specify the document input method, document size, color mode, and other settings.

[Original Input Method]

Select [Platen Glass].

[Input Size]

Specify the size of the scanning area. For normal cases, select the same size as the document. To specify the size with values, select a unit, and enter the values for width and height. To lock the width to height ratio of the image, click

The image size that can be scanned is limited on some applications.

[Color Mode]

Select the image type to scan documents.

[Black and White]	The document is scanned as a black and white image (in black and white only, with no intermediate shades of gray). You can change the threshold that separates text in the document or the image into black and white with [Threshold] (Adjusting Brightness and Color).
[Grayscale]	The document is scanned as a grayscale image (in black and white with intermediate shades of gray, similar to a black and white photograph).
[Color]	The document is scanned as a color image.
[Text Enhanced]	The document is scanned as a black and white image optimized for processing by OCR (optical character recognition) software.

Specifying Resolution and Image Size

Specify the output resolution and output size.

[Output Resolution]

Select the resolution of the scanned image that suits your intended use.

About the output resolution

A resolution of 75 dpi is a rough guide for displaying the scanned image on a computer, and 300 dpi for printing or creating a searchable PDF.

If you double the output resolution, the image file size increases by a factor of 4. If the file size is too large, a memory shortage or other error may occur. Set the resolution to the minimum required for your intended use.

[Output Size]

Select the size of the scanned image when it is printed or displayed on a computer.

Click

to switch between the portrait and landscape orientation. This button is not available when [Flexible] is selected.

If you select [Add/Delete], you can add new output size settings and delete the added sizes.

Select [Flexible] to change the output size and the ratio of width to height. Drag the area you want to scan on the preview image or enter values for width and height. If you specify the magnification percentage in the [%] entry field on the right side of the width and height entry fields, the document is enlarged or reduced for scanning.

[Data Size]

Displays the data size of the image when it is scanned with the set [Output Resolution] and [Output Size].

Adjusting Image Quality

Configure settings for improving the image quality, such as correction of scratches or faded colors on a photograph. These settings are available if you select [Color] or [Grayscale] for [Color Mode] (Specifying Settings for Documents and Color Mode).

[Auto Tone]

Automatically adjusts the color tone of the image.

[Reduce Dust and Scratches]

Makes dust or scratches on the document less noticeable. [High] makes large scratches and dust less noticeable, but may ruin details on the image.

[Fading Correction]

The setting is available if you select [Color] for [Color Mode]. Corrects faded colors on the document or enhances the color saturation of dull-colored documents. [High] dramatically corrects the faded colors, but may change the color tone of the entire image.

[Grain Correction]

Reduces graininess to create a smooth color tone when scanning photographs taken with high-speed film. [High] dramatically reduces graininess, but may also reduce image sharpness or degrade image quality.

[Use Unsharp Mask]

Emphasizes the edges and lines in the image, creating a sharper appearance.

[Use Descreen]

Reduces the color unevenness and moire that occur when scanning printed images.

Adjusting Brightness and Color

Configure color settings such as brightness, contrast, and color tone. The displayed items vary depending on the settings selected for [Color Mode] (Specifying Settings for Documents and Color Mode). When [Text Enhanced] is selected, you cannot configure these settings.

(Brightness/Contrast)

Adjusts the brightness and contrast (the difference between the light and dark parts) of the image. To adjust while checking on a graph, click

on the upper-right of the screen.

[Channel]

If you select [Color] for [Color Mode], you can adjust the [Red], [Green] and [Blue] color channels separately. To adjust all three colors at the same time, select [Master]. You can combine the adjustments made in [Master] and those made in the individual color channels.

If you select [Grayscale] for [Color Mode], only [Grayscale] is displayed.

[Brightness]
Slide

or enter a value.

[Contrast]
Slide

or enter a value. When contrast is reduced, the difference between the light and dark parts of the image is reduced to create a softer appearance. When contrast is increased, the difference between the light and dark parts is increased to create a bolder appearance.

(Histogram)

A histogram is a graph that shows the distribution of brightness in an image. You can adjust the image while checking the preview image and histogram. Specify the part of the image you want to make brightest (or darkest) in the preview image, so that the brightness balance of the original image is automatically adjusted with the specified part being the average. Likewise, you can also adjust the balance with the brightness of the medium tone being the average.

[Channel]

If you select [Grayscale] for [Color Mode], only [Grayscale] is displayed.

(Black-point Eyedropper)/

(Mid-point Eyedropper)/

(White-point Eyedropper)
Click the parts on the preview image (or cropping frame) you want to specify as the darkest, the medium, and the brightest. Slide

, or

. Alternatively, you can enter a value.

(Gray Balance Eyedropper Tool)
Click a part on the preview image (or cropping frame) you want to render as an achromatic color, which is black, grey, or white, each of which does not have color depth. Color tone on the rest of the image is adjusted with the clicked part being the average. For example, if snow on a photograph image is bluish, click this part because you essentially want to render this part as white. When you click this part, the snow is no longer bluish, and the entire image is adjusted so that it comes closer to natural colors. Click different parts little by little while checking the preview image to produce the optimum color tone.

(Tone Curve Settings)

The tone curve is a curved line that indicates the brightness and contrast levels of the image before and after adjustment. Select a registered tone curve to adjust the brightness and contrast levels of the image.

[Channel]

If you select [Grayscale] for [Color Mode], only [Grayscale] is displayed.

[Select Tone Curve]

[Under Exposure]	Darkens the entire image.
[High Contrast]	Emphasizes the difference between the light and dark parts of the image.
[Invert the Negative/Positive Image]	Inverts the light and dark parts of the image.

(Final Review)

The results of all adjustments made to the brightness, contrast (

), histogram (

), and tone curve settings (

) are displayed in a tone curve and as numerical values. Perform a final check of the color settings.

(Threshold)

Adjust the threshold value* for black and white images. You can enhance the appearance of text or reduce the visibility of text or images printed on the reverse side of a semi-transparent document, such as a newspaper. The setting is available if you select [Black and White] for [Color Mode].

* The threshold value is the boundary that separates whether a color is rendered as black or white. Colors below a certain density level are rendered as white, and colors above a certain density level are rendered as black.

[Threshold Level]
Slide

or enter a value. To render more parts as black, slide

to the right or enter a larger value.
