Resolution

The resolution is measured in dots per inch (dpi), which is used to represent the
image detail in a given area. The available resolution ranges from 50 to 19200.
Generally, the higher the resolution is, the sharper and higher the quality of the
scanned image gets. However, in some cases, high resolution is not necessary
because resolution is determined or limited by many factors: image type, the
original image's resolution, the output device's resolution, the available
memory space in your hard disks, etc.

Pointer

You can adjust the resolution by dragging the pointer to the desired resolution ,
directly key the value in the Edit box, or choose the value by clicking on the
pull-down button.

Edit box

Brightness

Brightness refers to the intensity of light reflected from or transmitted through
an image. The larger the brightness value, the brighter the image appears. You
can either drag the pointer, key the value into the Edit box to change the value,
or choose the value by clicking on the pull-down button.

Contrast

Contrast refers to the differences in the brightness between the light areas and
the dark areas of an image. The larger the contrast value, the higher the
differentiation between the light and the dark areas.You can either drag the
pointer, key the value in the Edit box to change the value, or choose the value
by clciking on the pull-down button.

The Zoom command allows you to enlarge the view of an image in the
Preview window. However, t he zo om function can only enlarge the
image view with one defined scale.

To zoom in:

Click the Zoom command. It w ill magnify the view in the Preview
window.

To disable zoom in:

After magnifyin g the view, click the Zoom command again to reduce the
view to its ori ginal size.

NOTE:

When zooming in, a vertical scroll bar and/or a horizontal bar will
appear to let you scroll thr ough t he entire im a ge.

Mirror

Mirror command lets you change t he horizontal orientation of a prescan
image to one that mirrors the current orientation of the image view across
a vertical im aginary line.

To mirror an image:

Click the Mirror command in the Image box.

Invert

The Invert function en ables you to make a positive view of a scanned
image negative or to make a negative image positive. By applying this
command, the brightn e ss value of ea ch pixe l will c hange t o an inver se
value on 256-color scale.

To invert an im age:

Click the Invert command from the Image box after a pplying the Prescan
function.

10

Descreen

Descreen filter is used to eliminate the moire patterns (wavelike lines) from
the images. As the images are scanned directly from screen-print media (like
newspapers or magazines), you should notice that the scanned images usually
come with wavelike patterns and banding lines. As long as the scanning
resolution is not set very high, you can apply this function to remove those
annoying effects. (When this function is activated, the scanning speed will
become slow.)

Click on the descreen icon, and a
dialog box titled "Descreen" will
appear. There are three items in the top
dialog box: Normal Scan, Default
Setting and Customize. Select
"Normal" then descreen will not
perform onto the scanned images.
Select "Default" to perform the default
setting of various document types. In
addition, select "Customize" to define
your own descreen level by entering a
desired value in the number box.

Gamma

Sometimes you wish to adjust the brightness of midtones of the scanned image
while keeping shadow and highlight areas relatively unchanged. The Gamma
correction function allows you to increase or decrease the intensity of the
middle gray tones.

The available gamma value
ranges from 0.01 to 7.99. The
default value is 1.0. Changing
the gamma value above 1.0 will
brighten the midtones, while
below 1.0 will darken the
midtones. You can either enter
the desired gamma value in the
edit box or use the scroll bar to
select your desired value.

To correct all color components (red, green, and blue) of the

image with the sam e gamma value.

To correct red compone nt of the image.

o correct green component of the image.

To correct blue component of the image.

If channel “All” is chosen, the gamma value is applied to all the

red/green/blue channel. Otherwise, gamma value for red/green/blue is

applied to red/green /blue component respectively.

HSV

Choose the HSV command from the Tools menu. The Hue & Saturation
dialog box will display and allow you to adjust the hue and saturation of
its pixels in an image while the brightness level remains unc hanged.

Hue is the wavelength of light reflected dire ctly from an image and it is
represented by the name of colors. The adjustment of the hue will change
the whole color appearance of the image. Saturation is the strength of the
color, referring to how far the color is from a gray of equal intensity. The
adjustment of the saturation will change the degree of the purity in
proportion to the hue.



To adjust Hue and Saturat ion:

1. Hue adjustment

In the “Hue” box, specify an angle value (you can either directly enter
the desired value in the edit box or use the scroll bar to select your
desired value). The specified angle value represents a move around the
color wheel. (Remember that hues are specified as angles on the color
wheel. If you are not f a miliar with the notation of

color wheel,

please

refer to any related books about color.)

12

2. Saturation adjustment

In the “Saturation” box, specify a desired percentage value of the
saturation. A value of –100 con verts the image completely to a
grayscale image and a value of +100 shows the image with fully
saturated hues.

Tone Adjustment

For the purpose of correcting image distortions that take place during the
scanning, you can use the Tone adjustment to make the compensation on
scanned images. Tone adjustment allows you control the conjunction
between the shadows, midtones, and highlights of your image. Use it to
restore detail that is missin g in shadows or highlights, to correct over or
under-exposure, and to improve the tonal quality of y our image.

From the Tools menu, choose “Tone”. A dialog box entitled “Tone
Adjustment” appears.

You can adjust the tone value by using the mouse cursor to reshape the
tone. Curve-based editing enables you to find out a problem area and
make subtle or notable change in that image area. The available range for
Tone Adjustment is from 0 to 255, and the defa ult value is x= 130 and
y=130.

The Tone Curve ta kes an original pixel brightne ss value X as input and Y
as a new output brightness value. The resulting curve is a visual
representation of the balance between shadows, midtone s, and highlight s.

13

Auto Color Control

The Auto Color Contr ol automatical ly adjusts the colors of the scanned
document spread over a 256-color scale. Before performing this function,
please click on the Preview icon first.

Color Correction

Click on Color Correction icon, and a dialog b ox will appear. Choose
Disable Color Correction item for scanning without color corrected.
Choose Enable Color Correction item for color correction to acquire high
fidelity images. If you check Enable Color Correction, the scanning
speed will become slow.

Image Enhancement Tools – Special Effect

p

Special effect tool enables you to create special and spectacular
effects in your scanned image. As you move the pointer to the left,
you will get the Blur effect. Reversely, as you move the pointer to
the right, you will get the Sharpen effect.
