7. Digital noise reduction function setting [DNR]
The digital noise reduction function reduces noise automatically under the condition of low illuminance. The effect level of the noise reduction function is selectable from the following:
LOW: Low level of noise reduction (small residual image)
HIGH (default): High level of noise reduction (large residual image)

•The auto back focus function also allows users to correct out of focus when changing between color and
•If a subject is always moving or the screen is occupied with a uniform color, brightness determination may be not performed suc- cessfully because the brightness is merely determined by information from the CCD image sensor. When "AUTO2" is selected, the wave length of the light source shall be 800 nm or longer.
Step 2
Press the setting button.
→The "BW MODE" screen appears.
Step 3
Move the cursor to "LEVEL" and select a brightness level at which switching between color and

Note:
• To obtain color images, a sufficient level of illuminance (approx. 30 lx or more) is required.
• The switching illuminance level varies with subjects, light sources, and lenses.
• The switching illuminance level varies in accordance with AGC setting. (+ page 12)
• The switching illuminances described above are reference values. The switching illuminance shall be decided based on the actual
