Sharpness, SmartFocus, Smoothing

Page 251 highlights

● Sharpness. Many images are improved by increasing their sharpness. Use the Sharpness feature to make edge detail more prominent. The filter detects regions that contain significant variations in pixel value along a number of different vectors (which denotes edges) and then applies a filter to enhance detail. ● SmartFocus. Use the SmartFocus setting to increase the apparent resolution of lower resolution images. Many images that are downloaded from the Internet or from digital cameras can be compressed because of size restrictions, and might exhibit pixilation artifacts when printed. SmartFocus upscales the image to the printer resolution without accentuating these artifacts. ● Smoothing. Just as many images benefit from increased sharpness, many images are improved by smoothing, which decreases noise artifacts that digital cameras or scanners often create. When you select Smoothing, the filter locates areas that contain abrupt changes in pixel value by comparison with surrounding pixels (which denotes noise) and then applies a filter to smooth the output.

Sharpness
. Many images are improved by increasing their sharpness. Use the
Sharpness
feature
to make edge detail more prominent. The filter detects regions that contain significant variations
in pixel value along a number of different vectors (which denotes edges) and then applies a filter
to enhance detail.
SmartFocus
. Use the
SmartFocus
setting to increase the apparent resolution of lower resolution
images. Many images that are downloaded from the Internet or from digital cameras can be
compressed because of size restrictions, and might exhibit pixilation artifacts when printed.
SmartFocus upscales the image to the printer resolution without accentuating these artifacts.
Smoothing
. Just as many images benefit from increased sharpness, many images are improved
by smoothing, which decreases noise artifacts that digital cameras or scanners often create. When
you select
Smoothing
, the filter locates areas that contain abrupt changes in pixel value by
comparison with surrounding pixels (which denotes noise) and then applies a filter to smooth the
output.
