Resolution enhancement

Select one of the following options to enhance the original image resolution and improve the recognition quality.

Resolution enhancement option	Description
No	No resolution enhancement is applied.
Yes	Enhancement is applied with the ratio of 2:0.
Legacy	The ratio of enhancement depends on the resolution of the non-BW (black-and-white) image. If the resolution is 160 DPI or less, the ratio of 2:0 is applied. If the resolution is between 160 and 210 DPI, the ratio of 1:5 is applied.
