Agc Control; Backlight Compensation; Aperture; Motion Detection - Panasonic GP-MH310 series Technical Manual

Function Descriptions
If the illumination of the subject decreases, the
Prolonged Exposure Control is automatically
executed along with the AGC Control.
The maximum Field Accumulation Time can be
configured to a range of 1x to 64x.
This cannot be configured during the following
conditions.
When the MOTION settings are valid.
When AGC is OFF.
In addition, the shutter speed mode is set to OFF.

[6] AGC Control

AGC ON
⁃
The gain is automatically controlled and light is fixed
to a certain intensity.
The MAX gain of each mode of LOW/NORMAL/
MIDDLE/HIGH is roughly equivalent to the following
gains.
AGC Gain (dB)
LOW2 LOW1
AUTO 24dB 27dB
COLOR 24dB 27dB
B/W 24dB 27dB
(LOW1/LOW2/LOW[AUTO] modes could be
selected only from the Version 1.01-02 or later)
AGC OFF
⁃
This is the fixed gain mode. The gain value can be
manually configured to 15 steps.*
The gain value of each step is roughly equivalent to
the following gains.

[7] Backlight Compensation

Multi-Area Light Measuring
⁃
This automatically detects the subject area, the
backlight conditions, and automatically corrects the
backlight.
The following settings configure sensitivity and the
effectiveness of corrections when there is backlight.
BLC Weight
The sensitivity to backlight can be configured to a
range of 0 to 15.
Larger values increase the sensitivity to backlight.
BLC Bright
The target brightness value of the subject area
when there is backlight can be configured to a
range of 0 to 15.
Larger values increase the effectiveness of the
correction.
Center-weighted metering
⁃
The 256 total areas are divided into 5 and
brightness levels are corrected by weighting and
calculating each area.
The weight of each area can be configured to a
range of 0 to 7. (CENTER is fixed at 7.)
The CENTER position and size can be changed
according to the position of the subject.
BLC Mask
⁃
By specifying masked areas within the 256 total
areas, brightness information of the masked areas is
ignored and brightness levels are corrected.
Note: When the Day/Night switch control is
⁃
set to AUTO mode, the backlight cannot
be corrected with multi-area light
measuring when the camera is set to
B/W.

[8] Aperture

Emphasizes contours and increases the vividness of
the entire image.

[9] Motion Detection

The screen is divided into 256 areas (16 x 16) and
movement is detected from changes in brightness of
representative points within each area.
The detection status can be confirmed by enquiring
using the Status command.
In addition, the detection sensitivity can be adjusted
by configuring the following items.
Sensitivity (MOVE)
⁃
Sensitivity when determining movement can be
configured to a range of 1 to 10. 1 is the most
sensitive to movement.
