• If the object is too close, wash out may result, rendering the
white balance adjustment ineffective. Adjust the distance to
the object to display a medium level of brightness on the
video monitor.
• A variety of factors, such as the color adjustment of the bulb
in the light source, the size of the color image rendered by
the endoscope or the combination of ancillary equipment
may affect the auto white balance function. If further
adjustment is needed, refer to “Color tone level (red/blue)
adjustment” on page 75.
• When using the CLE-10 or CLE-F10 light source, set the
brightness to maximum to maintain the color tone balance.
• When using the CLD-S light source, wait at regular intervals
until the light is stable to adjust the white balance.
• When using the CLD-S light sources, refer to Section 5.6,
“Setting color mode” and set the color mode on the OTV-S7V
to “<4: METAL HALIDE>”.
• If the color on the video monitor is not adjusted properly,
white will not appear on the video monitor, even if white
balance is performed. Adjust the PHASE and CHROMA
knobs on the video monitor and refer to Section 5.4,
“Adjusting the video monitor”.
• Refer to Section 5.12, “Remote control switches” for
instructions on setting auto white balance using the remote
control switches on the camera head or videoscope.
• For more information on the remote control switch functions,
refer to Table 5.3 on page 111 – 113.
