O

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 

 used, or high speed without false 

color processing and noise reduction function used.

O

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 

 

to reduce the luminance noise and chrominance noise.

O

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.

O

We recommend that you normally set [High quality] for a balance 
between image quality and display speed.

O

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.

O

As the [View images at high speed (moiré reduction off)] setting is the 
same as [High quality] other than for display of the image, the image 
undergoes false color reduction processing when it is saved and the 
noise reduction function is also available.

O

Since false color reduction processing is not applied, the display 
speed of a RAW image in the edit window or the edit image window in 
the [100% view] or [200% view] enlargement display, and the time it 
takes to save a RAW image is less than in [High quality].

O

You cannot use the noise reduction function 

O

Depending on the image, it may be displayed/saved with false color 
or noise being noticeable.

The display image quality of [High quality] and [High speed] is the same 
except when the image is displayed in the [100% view] or [200% view] 
enlargement display in the edit window or the edit image window.

O

O

You can improve the quality of a JPEG image by reducing the noise 
that is likely to occur when RAW images are converted to JPEG 
images and saved 

.

This setting is also effective for JPEG images that have been saved 
with a different name.

O

You can have the thumbnails for JPEG images automatically displayed 
at high quality. If you checkmark [Display thumbnails at high quality], 
all subsequent JPEG image thumbnails imported into DPP will be 
displayed at high quality.

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.

O

You can set the resolution for RAW images converted and saved as 
JPEG or TIFF images 

.
