5, SUPPLEMENTAL INFORMATION
(1) "Color temperature"
Light is composed of various color components in differ-
ent proportions. A relationship exists between tempera-
ture of a light source and the components of the emitted
light; as the temperature rises, the color of light
varies from red, orange, yellow, white to blue in that
order. "Color temperature" is a value that expresses
differences in color among light sources, measured in
Kelvin degrees. Bluish light has a higher color
temperature than reddish light.
(2) "White balance"
Making the colors look natural on TV monitor is what
white balance is all about. Because a camera is not as
adaptable as the human eye, if a light source is reddish,
white subjects in that light are recorded as reddish.
White balance adjustment is performed to compensate for
color temperature variations of light so that whites are
reproduces as white. Correct white balance makes all
other colors correct.
The CS5131P can perform automatic white balance adjust-
ment with just the press of a switch.
However, if illumination is insufficient, white balance
adjustment cannot be performed. To obtain correct colors,
therefore, sufficient illumination is essential.
(3) How to get good color pictures.
The simplest way is to provide sufficient lighting(close
to the camera's reference illuminance) and accurately
adjust the camera to the color temperature of that
lighting.
If light sources of different color temperatures are
used together, accurate white balance adjustment is very
difficult. For example, if natural light is mixed with
some artificial light, which is likely to occur next to
windows, correct colors of the subject are difficult to
obtain. It is recommended that incandescent or halogen
lamps not be used together with flourescent lighting.
