Setting value
[Factory default]
This can be set when "Bit shift" is selected for "Operation type".
Set the bit shift method.
• Right bit shift
• [Right bit shift] Bit shift to the right. This makes the pixel values smaller and the image
• Left bit shift darker.
• Left bit shift
Bit shift to the left. This makes the pixel values larger and the image
brighter.
This can be set when "Bit shift" is selected for "Operation type".
Set the shift value used to convert the pixel values. The result of bit shifting of
1 to 8 [1]
each pixel value according to the bit shift mode, and repeated the number of
times set with the shift value, is the converted pixel value.
This can be set when "Change pixel value" is selected for "Operation type".
Set the method used to convert the pixel values.
• [Change inside • Change inside bounds
bounds] Pixel values inside the range set in "Change bounds" are converted using
• Change outside the "Change value".
bounds • Change outside bounds
Pixel values outside the range set in "Change bounds" are converted using
the "Change value".
This can be set when "Change pixel value" is selected for "Operation type".
Set the value used to convert the pixel values. The pixel values that are
1 to 255 [128]
specified by the "Change mode" are converted to the value set in "Change
value".
This can be set when "Change pixel value" is selected for "Operation type".
[1] to [255]
Set the range of pixel values to be converted.
