The camera CCD responds to infrared light(700 ~
~~
~
1000nm) that is invisible to the human eye. Normal color
camera uses an IR cut filter to remove the infrared
components in order to bring it close to human eye. This
condition is used for color image. In case of black and
white image, the IR cut filter is removed in order to making
it more sensitive for infrared light.
Note
1) When using infrared light, the switching of color
picture ⇔ black and white picture might occur
according to the picture shooting conditions such as
strong light or the distance from the subject is short. In
this case, decrease the brightness of the illumination.
2) Under the picture shooting condition without the
infrared light, sensitivity is not increased even if it
switches to a monochrome image.
3) Focal plane of the lans is different for visible light(color
picture) and black and white picture. Therefore,
adjusted focus for color picture shifts when mode
switches to black and white picture. Use the lens
sensitive to infrared light, in case of BW MODE.
