5[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 33 dB (approximately 45 times) in the LOLUX mode.

•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 82.

6[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 portion 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 section is compressed to increase the contrast.

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 OPERATION menu screen. (☞ See page 73.)

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

being, 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 human being indoors with a view
	to the landscape out through a window.
•	When shooting a human being 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.

For servicing

→ Even during FAS operation, the priority setting for the audio recording level is “CH1/CH2 AUDIO SELECT”.
