2. CONTROLS, INDICATORS AND CONNECTORS

7[BLACK] Black stretch/black compression switch

Switches the gain for the dark section of the image.

Set to an appropriate position depending on the video signal to be shot.

STRETCH : By stretching the signal only for the dark section, contrast in the dark sections of the image is enhanced.

NORMAL : Standard mode.

COMPRESS : When an entire image is relatively light and the contrast is low, the gain of the dark sections is compressed to increase the contrast.

8[LOLUX] LOLUX On/Off button

This button toggles the LOLUX mode on and off.

LOLUX gain gives extremely low light level sensitivity for special applications. This will result in an increase of 30 dB in the LOLUX mode.

The gain up value can be selected from the menu.

See page 71.

LOLUX operation takes priority over normal gain setting.

If the unit is placed in the LOLUX mode when it is in full auto shooting mode, the auto level control (ALC) (one of the full auto shooting functions) will be made inactive, so that the LOLUX mode is given preference (FAW still remains active).

See “GAIN BOOST UNDER LOLUX CONDITION” on page 86.

9[CAM] Camera mode indicator

This indicator lights when the camera is in the Camera mode. To record the camera image, press the MODE switch ^ to turn on this indicator. When the power is turned on, the mode becomes the Camera mode.

0[VTR] VTR mode indicator

This indicator lights when the camera is in the VTR mode.

To perform VTR playback or to input the DV signal from the DV connector 6 on page 19 (DV signal input is possible with the GY-DV5001.), press the MODE switch ^ to turn on this indicator.

![POWER] Power ON/OFF switch

This switch is used to turn the power on and off.

“POFF” is displayed on the LCD monitor or in the viewfinder when the power is turned off.

*Wait 5 seconds or more before turning the power on again after it has been turned off.

@[VTR] Trigger button (Recording Start/Stop)

This button is used to start and stop recording.

(It is interlocked with the VTR trigger button on the front and the VTR trigger button on the lens section.)

#[GAIN] Sensitivity selector switch

Electronically boosts the light sensitivity when there is insufficient illumination on the subject. The boosting level differs depending on the switch position as follows:

(Factory presets)

L : 0 dB (no boosting is applied)

M : 9 dB (boosted to approximately 3 times the original)

H : 18 dB (boosted to approximately 8 times the original)

The boosting level for each switch position can be changed with the CAMERA OPERATION MENU screen.

See page 71.

The more the boosting level is increased, the more the resulting image will be noisy.

$[OUTPUT] Color bar/Camera/Auto knee switch

This switch is used to select the output signal. When the video signal from the shooting camera is selected, the auto knee function is available.

CAM. AUTO KNEE ON: Outputs the video signal from the shooting camera. In this mode, the auto knee function is available.

CAM. AUTO KNEE OFF: Outputs the video signal from the shooting camera. In this mode, the auto knee function is not available.

BARS: Outputs the colour bar signal. In this mode, the auto knee function is not available. Set to this position when adjusting the video monitor or when recording the colour bar signal. Color bars will not appear when Full Auto is set to ON or when in the VTR mode.

AUTO KNEE function

When shooting a foreground subject, such as a person, etc., with a high-brightness background, if the brightness level is set for the foreground subject, the background image will be blurred with white. In such a case, a clearer background is obtained when the auto knee function is used. It is effective especially in the following cases:

When shooting a person indoors with a view to the landscape out through a window.

When shooting a person in the shade on a fine day.

When shooting a high-contrast scene.

CAUTION:

If a fast moving high-brightness section like a car in sunlight is shot, the auto knee function may change the brightness of the entire image along with the motion of the object. In this case, set the auto knee function to OFF.

%[WHT.BAL] White balance switch

Three white balance modes are selectable with this switch.

B : If white balance is performed with the switch in this position, it will be memorized into B.

A : If white balance is performed with the switch in this position, it will be memorized into A.

PRST : A non-erasable white balance setting at 3200K.

(PRESET)

FAW (Full-time Auto White) mode can be set to A, B or PRESET with the CAMERA OPERATION menu. See page 71.

In the FAW mode, video colour temperatures are constantly sampled for automatic adjustment to a proper white balance.

^[MODE] Mode switching switch

This is a switch to select either the Camera mode or the VTR mode. Each time this switch is pressed upward, the mode is switched to either the Camera mode or the VTR mode and the CAM indicator 9 or VTR indicator 0 lights in accordance with the selected mode.

Select the Camera mode to record the camera image.

Select the VTR mode to playback or to output the DV signal from the DV connector 6 on page 19. (DV signal input is possible with the GY-DV5001.)

When the power is turned on, the mode becomes the Camera mode.
