Automatically adjusts the sensitivity for up to the
designated maximum level. Change the incremental
parameter when giving more consideration to a residual
image reduction than to a sensitivity level increase.
Normally, use this mode.
Use this mode to automatically adjust a AGC level without
using the sensitivity increasing function, and create
pictures free from residual images in poor lighting
conditions.
The AGC level is always maintained at a set level of 0-18
dB, and a sensitivity level automatically increases to up to
the level of the designated incremental parameter as the
lighting condition worsens. Use this function when noise is
a greater annoyance than a residual image.
Handles changes in brightness by means of the lens iris
only. Use this function when noise or residual image is an
annoyance.
White Balance Setting
•
White balance setting screen 1
Three modes are made available for selection: ATW, AWB, MANUAL
ATW: The camera's white balance varies as the object's color temperature varies.
AWB: Once the camera's white balance is adjusted during its installation, the camera operates on
the initially-set white balance even though the object's color temperature changes.
MANUAL: To adjust the white balance so that the color looks natural when an object is viewed under a
special light source.
Move the flashing [ ] cursor with the key and the
key to select the desired mode out of the four modes, then
press the SET key for registration.
When ATW is selected, the [ ] cursor in the indication of
"RED – – + – – BLUE" flashes and the level can be varied
with the
key and the key, thereby permitting the
white balance offset to be changed. Pressing the SET key
here for registration will return the display to the initial
screen.
Note
Because the camera readjusts the white balance
depending on a subject, several seconds may be
required till the [
] cursor begins to flash after ATW has
been selected.
When AWB is selected, Setting Screen 2 (on the next page) is displayed.
When MANUAL is selected, Setting Screen 3 (on the next page) is displayed.
Note
When the ATW switch is placed in the AWB position, the mode is always set for AWB.
Note
The sensitivity increasing function is realized by making longer than usual the time required to store light in
the image sensor. For this reason, if an object becomes dark, a residual image phenomenon take place.
