How to Process Low-Resolution Images

Operation

Tip: Readiris detects the typical fax resolutions - 100 x 200 dpi (normal quality), 200 x 200 dpi (fine quality) and 200 x 400 dpi (superfine quality) - and preprocesses these images automatically to ensure optimal OCR results.

Tip: should you have any influence over your correspondents, ask them to send faxes with the “fine” quality - those faxes have the higher resolution of 200 dpi and will yield better OCR results.

Digital Camera

Enable this option when the images were produced by a digital camera!

Process as 300 dpi

Use this option to read images generated with a digital camera - where the resolution is unknown - and to open images where the file header contains an incorrect resolution.

Thanks to this option, the images will be processed “normally”, as if they had a 300 dpi resolution. (You also avoid a warning that you’re submitting images with a resolution lower than 200 dpi or higher than 800 dpi.)
