Wide Dynamic Range Mode (WD)

The Wide Dynamic Range mode is a function for

dividing an image into several blocks and correcting

blocked-up shadows and blown-out highlights in

accordance with the intensity difference. It enables you

to obtain images in which portions ranging from dark

to light can be recognized, even when capturing a

subject with a large intensity difference that is backlit

or includes extremely light portions.

Images with wide dynamic range are produced by

combining long-exposure signals (normal shutter) with

the signals of the high-intensity portions obtained with

a short exposure (high-speed shutter).

p: WIDE D (Wide dynamic range mode)

When MODE (exposure mode) is set to FULL

AUTO, the camera distinguishes light and dark

areas in the same scene, adjusts the brightness

for dark areas, and also controls the blown out

highlights.

You can select the wide dynamic range mode

from among OFF, LOW, MID and HIGH.

(0: OFF, 1: LOW, 2: MID, 3: HIGH.)

Notes

• You can set the wide dynamic range mode when the WIDE D is

set to FULL AUTO only.

• When the WIDE D is not set to OFF, the MODE setting is fixed at

FULL AUTO.

• When changing the WIDE D, the luminance change of the screen

occurs for a moment.

• When the change of exposure is big, the screen may stop for a

moment.

• When the wide dynamic range mode is ON, false colors may

appear in some parts of the image. This phenomenon is unique to

wide dynamic range mode, and is not an indication of a camera

malfunction.

• When switching wide dynamic range mode, images are shown at a

maximum of 8 frames at the same time.

• When the intensity difference of the image is small, there is no

difference in effect between MID and HIGH.

Exposure Compensation

Exposure compensation is a function which offsets the

internal reference brightness level used in the AE

mode, by steps of 1.5 dB.

The reference brightness is 0.

High Resolution Mode

This mode enhances edges and produces higher

definition images.

Aperture Control

Aperture control is a function which adjusts the

enhancement of the edges of objects in the picture.

There are 16 levels of adjustment, starting from "no

enhancement. " When shooting text, this control may

help by making them sharper.

Back Light Compensation

When the background of the subject is too bright, or

when the subject is too dark due to shooting in the AE

mode, back light compensation will make the subject

appear clearer.

Noise Reduction

The NR (Noise Reduction) function removes noise

(both random and non-random) to provide clearer

images.

This function has six steps: levels 1 to 5, plus off.

The NR effect is applied in levels based on the gain,

and this setting value determines the limit of the effect.

In bright conditions, changing the NR level will not

have an effect.
