Abstract
An image processing system such as a multi-function device (MFD) with an 'e-reader' mode is disclosed. The e-reader mode can be activated by a user from the MFD user interface, or automatically detected by the system if the mode is set to 'auto.' Once in e-reader mode, the system automatically locates the area corresponding to the e-reader screen, crops it, de-skews it when necessary, and enhances the image. In addition, N-Up (printing several pages of content on one physical page) may be applied if users desire. The enhancement adjusts background color, boosts the contrast, and de-blurs the image when necessary. Two embodiments of enhancement are presented. The first one performs Tone Reproduction Curve (TRC) adjustment and possible de-blurring on the entire screen area. The second one segments the screen area into three kinds of objects (text/picture/background). Different TRCs are applied to enhance the objects.
