 Viewing and saving RAW images
You can select from two types of image quality for displaying/saving
RAW images: high image quality with false color reduction processing
and noise reduction function (p.62) used, or high speed without false
color processing and noise reduction function used.
[High quality]
 False color reduction processing is automatically applied, and the
image can be displayed/saved as a false color reduced-high quality
image. Furthermore, you can use the noise reduction function (p.62)
to reduce the luminance noise and chrominance noise.
 Because the effects of the false color reduction processing and noise
reduction function are difficult to see in the [50% view] or [Fit to
window] display of the edit window and edit image window, use
[100% view] or [200% view] to check.
 We recommend that you normally set [High quality] for a balance
between image quality and display speed.
[View images at high speed (moiré reduction off)] of [High quality]
 If you checkmark [View images at high speed (moiré reduction off)],
when the image is displayed in the edit window or the edit image
window, false color reduction processing is not applied. However, you
can use the noise reduction function.
 As the setting is the same as [High quality] other than for image
display, the image undergoes false color reduction processing when it
is saved.
[High speed]

Since false color reduction processing is not applied, the display speed
of a RAW image in the edit window or the edit image window, and the
time it takes to save a RAW image is shorter than with [High quality].
 You cannot use the noise reduction function (p.62).
 Depending on the image, it may be displayed/saved with false color
or noise being noticeable.
For images shot with ISO speed range expansion set, the difference
in image quality between [High quality] and [High speed] becomes
remarkable. To check the image quality of images shot with ISO
speed range expansion, make sure to set [High quality] and check
the images in the edit window or edit image window.
 JPEG image quality
[Remove block noise and mosquito noise]
 You can improve the quality of a JPEG image by reducing the noise
particular to JPEG images.
This setting is also effective when RAW images are converted to
JPEG images and saved (p.42, p.99) and for JPEG images that have
been saved with a different name.
The higher the JPEG image’s compression rate, the more noise is
reduced. When the compression rate is low, the effect of noise reduction
is negligible.

Default value of output resolution
You can set the resolution for RAW images converted and saved as
JPEG or TIFF images (p.42, p.99).
