２） Image processing
⑴Picture Styles
The same Picture Styles found in the EOS 30D are
incorporated. In the Creative Zone modes, when you press
the SET button, the Picture Style selection screen appears
(Fig. 004). It is now easier to select a Picture Style.
⑵Noise reduction
As with the EOS 30D, the [Long exp. noise reduction]
Custom Function can be set to [Off], [Auto], or [On].
With [Auto], noise reduction is performed
automatically for exposures 1 sec. or longer if the noise peculiar to long exposures is
detected. [On] can be set if the [Auto] setting fails to detect and reduce the noise. Note that
while the noise reduction is performed on an image, the camera cannot take any pictures.
⑶White balance
The white balance settings, white balance correction, and bracketing are the same as
with the EOS KISS DIGITAL N.
３）Dust reduction
The EOS D REBEL XTI / EOS 400D D is the first EOS DIGITAL camera to have the automatic
dust reduction feature of imaging sensor to remove dust and bundled software to obtain Dust
Delete Data to erase dust spots automatically. As with previous models, manual cleaning of
the sensor is also possible.
⑴Self Cleaning Sensor Unit
Dust adhering to the low-pass filter in front of the sensor
is removed by ultrasonic vibration (Fig. 005).
Normally, when the power switch is turned on or off, the
Self Cleaning Sensor Unit operates automatically for about
1 sec. to remove any dust. The system can also be activated
manually with a menu (Fig. 006). Since shooting-priority
still takes effect, pressing the shutter button during the
self-cleaning operation will interrupt the self-cleaning and
return the camera to shooting ready.
The vibration and noise levels during the operation
of the Self Cleaning Sensor Unit are low enough to be
unnoticeable. You can hear a whispery noise only if you
put the camera next to your ear during the self-cleaning
operation.
The removed dust is held by dust-sticker material
around the low-pass filter to prevent it from adhering to
the sensor again.
