When images in the near-infrared light area change from color to black & white, images may be out of
focus due to the nature of optical properties. In this case, the focus can automatically be corrected by
selecting “Auto” or “Preset” for “Adjusting method” (the focus will not automatically be adjusted
according to the illumination level change once the focus is corrected).
[Adjusting method]
Select the focus adjustment method upon switching between the color mode and the black & white mode.
•
Auto:

black & white images.
•

memorized for each of color images and black & white images.
