11.6.2 Configure the settings relating to image quality (“Image adjust” setup menu) (SF346, SF342, SF336, SF335, SF332, SP306, SP305, SP302)
The settings relating to image quality can be configured with the setup menu displayed in a newly displayed window. When the values are changed, the changed values will be applied to the currently displayed image on the [Image quality] tab.
IMPORTANT
•
Image adjustment functions are activated for the angle of view in the aspect ratio of 4:3 even while “16:9” is being selected for “Aspect ratio”.
[Wide dynamic range (WDR)]
Select “On” or “Off” to determine whether or not to activate the wide dynamic range function.
This function compensates brightness so that it produces clearer images even if objects have various illumination intensities.
•
On: The wide dynamic range will work.
•
Off: The wide dynamic range will not work.
IMPORTANT
•
When the wide dynamic range function is activated, noise may be increased in the dark area of the object.
•
The setting is available only when “Outdoor scene”, “Indoor scene (50 Hz)” or “Indoor scene (60 Hz)” is selected for “Light control mode”.
[Face SD]
With the “Face SD” setting, if a person's face is dark and difficult to see, by combining the face detection and wide dynamic range functions, the area with the face in the image can be corrected to become brighter and easier to see.
Select “On” or “Off” to determine whether or not to interact with the face detection function.
•
On: The interactive control with face detection will work. The dynamic range is controlled in accordance with the illuminance level around the face.
•
Off: The interactive control with face detection will not work.
Note
•
When “Off” is selected for “Wide dynamic range (WDR)”, the interactive control with face detection is deactivated.
•
There may be some cases that the effect is not distinct when the faces are too dark to recognize due to strong backlight.
[Adaptive black stretch]
Select “On” or “Off” to determine whether or not to activate the darkness compensation function. The darkness compensation function can make darker parts of images brighter by digital image processing.
When “On” is selected for “Wide dynamic range (WDR)”, this setting is unavailable.
•
On: Activates the darkness compensation function.
•
Off: Deactivates the darkness compensation function.
IMPORTANT
•
When “On” is selected for “Adaptive black stretch”, noise in the darker parts may be increased, and parts around borders between the darker parts and the brighter parts may become darker/brighter than the other darker/brighter parts.
[Back light compensation (BLC)]
Select “On” or “Off” to determine whether or not to activate the back light compensation (BLC) function. When “On” is selected for “Wide dynamic range (WDR)”, this setting is unavailable.
The back light compensation function can compensate back light by setting mask areas on brighter parts of images.
•
On: Mask areas will be set automatically.
•
Off: Mask areas will not be set automatically. It is necessary to set them manually.
[Mask area]
When “Off” is selected for “Wide dynamic range (WDR)” and “Back light compensation (BLC)”, it is possible to compensate for backlight by masking brighter areas.
[Light control mode]
Select the light control mode from the following.
•
Outdoor scene: Depending on the brightness level (illuminance), the iris will automatically be controlled together with the shutter speed adjustment to control light. When shooting a bright subject such as outdoor, etc., select this parameter. Be aware that flicker may occur when a subject is under fluorescent lighting.
•
Indoor scene (50 Hz) / Indoor scene (60 Hz): The shutter speed will automatically be adjusted to prevent flicker caused by fluorescent lighting. Select 50 Hz or 60 Hz corresponding to the location where the camera is in use.
•
Fix shutter: The selected value will be set as the fixed shutter speed.
1/30 Fix, 3/100 Fix, 3/120 Fix, 2/100 Fix, 2/120 Fix, 1/100 Fix, 1/120 Fix, 1/250 Fix, 1/500 Fix, 1/1000 Fix, 1/2000 Fix, 1/4000 Fix, 1/10000 Fix
Note
•
When a faster shutter speed is selected (up to 1/10000), it is possible to capture a fast moving object with less blur.
•
When a faster shutter speed is selected, the sensitivity will become lower.
•
When “On” is selected for “Wide dynamic range (WDR)”, “Fix shutter” is not available. To configure “Fix shutter”, set “Wide dynamic range (WDR)” to “Off”.
[AGC]
Select a method of gain adjustment from the following.
•
On(High)/ On(Mid)/ On(Low): When the luminance of the subject becomes darker, gain will be automatically increased and screen will become brighter. “High”, “Mid” and “Low” are indications of gain level.
•
Off: Images will be captured with the fixed gain level.
[Auto slow shutter]
The electronic sensitivity enhancement (sensitivity up) can be carried out by adjusting the storage time of MOS.
The following are available for the recording duration.
Off(1/30s), Max.2/30s, Max.4/30s, Max.6/30s, Max.10/30s, Max.16/30s
IMPORTANT
•
When “On” is selected for “Auto slow shutter”, frame rate may become lower. Noise or white dots (blemishes) may sometimes appear.
Note
•
When “Max.16/30s” is selected, for example, sensitivity will automatically be increased up to x16. When “Off” is selected for “AGC”, this setting is unavailable.
Select switching between the color mode and the black & white mode from the following.
•
Off: The color mode is selected.
•
Auto: Switches from color to black-and-white images when the ambient brightness (illuminance) of the camera is approx. 1.0 lx or less. It takes time to switch between modes.
[Day & Night(IR)]

Select switching between the color mode and the black & white mode from the following.
•
Off: The color mode is selected.
•
On: The black & white mode is selected.
•
Auto1(Normal): The camera automatically switches between the color mode and the black & white mode in accordance with picture brightness (luminance). The black & white mode will automatically be selected when the lighting condition becomes darker, while the color mode will automatically be selected when it becomes brighter.
•
Auto2(IR Light): Suitable when using a near-infrared light source at night.
Note
•
The operating sound might be heard when changing to black-and-white mode, however it does not indicate any malfunction.
[Level]

Select the threshold illuminance level (brightness) to switch between the color mode and the black & white mode.
•
High: Switches from the color mode to the black & white mode when the ambient brightness (illuminance) of the camera is approx. 6 lx or less.
•
Low: Switches from the color mode to the black & white mode when the ambient brightness (illuminance) of the camera is approx. 2 lx or less.
[Dwell time]

Select a wait time for switching between the color mode and the black & white mode from the following.
2s/ 10s/ 30s/ 1min
[White balance]
Select a method of white balance adjustment from the following.
White color can be adjusted by “Red gain” and “Blue gain”.
•
ATW1: Selects the automatic tracing white balance mode. The camera will constantly check the color temperature of the light source and adjust the white balance automatically. Operating color temperature range is approx. 2,700 K to 6,000 K.
•
ATW2: Selects the automatic tracing white balance mode under a sodium lamp. The camera will adjust the white balance automatically under a sodium lamp. Operating color temperature range is approx. 2,000 K to 6,000 K.
•
AWC: Selects the automatic white balance control mode. This adjustment is suitable for a location where a light source is stable. Operating color temperature range is approx. 2,000 K to 10,000 K.
Note
•
Under the following conditions, color may not be faithfully processed. In these cases, select “AWC”.
–
When shooting a subject whose major part is a thick color
–
When shooting blue sky or sun at sunset
–
When shooting a subject whose luminance is too low
•
When “AWC” is selected, click the [Set] button.
