Appendix - Peculiarity of color -

Color is expressed by hue, saturation and value.

Saturation

(Chroma)

The degree of the vividness of color

Low : Monotone color
High : Close to pure color

Value

(Lightness)

The degree of light and the
shade of color

Color Pickup Mode

Hue

The color attributes such
as red, blue, and green

In color pickup mode, color image will be converted into binary image by three parameters - hue, saturation and value.
Specifying picked up color, its corresponding part of the space in color cube will be converted into "1", and the other "0".
Monotone color that cannot be treated by color gray filter, can be e xtracted in color pickup mode.

The picked up color will be
converted into "1".
The part of "1" will be
displayed by picked up
color in F400.

The colors excluding picked up
color will be converted into "0".
The part of "0" is displayed by
black at default, but it can be
converted into 5 colors "from
black to white".

Colorgray filter in color filter mode

In colorgray filter, color image will be converted into gray image using hue and saturation, but lightness isn't
considered during conversion.
The density of gray image after conversion depends on the point on hue/ saturation plane of color image.

Low

Hue

High

Hue/saturation plane

Saturation

Density of colorgray image
= Saturation of measured color - (Hue of registered color - Hue of measured color)

(Ex.) Registered color: blue

Registered color

Blue

Light blue

Red

Select registered color out of 256 hues. Color bar displayed left side of a screen indicates hue.
Highest chroma colors in each hue are lined up on the color bar.
So blue must be selected on the color bar when light blue is to be registered.

As measured color is as close as registered color
and high chroma, it will be white in gray image.

Though hue is registered color, it will be gray in
gray image because of low saturation.

As measured color is as far as registered color, it
will be black in gray image though high
saturation.

See next page for the setting of color g r ay filter.
