Claim One:
1. An image processing apparatus for translating a source image in a first resolution from an input device into an output image in a second resolution for an output device comprising: an image buffer for receiving and storing said source image; a text segmentation unit for forming a black text image and a white text image from said source image stored in said image buffer; a black text image buffer for storing said black text image and a white text image buffer for storing said white text image; an image separation unit coupled to said image buffer, said black text image buffer and said white text image buffer for separating said black text image and said white text image from said source image to form a background image; a first filter for filtering said black text image to produce a filtered black text image and a first resultant buffer for storing said filtered black text image; a second filter for filtering said white text image to produce a filtered white text image and a second resultant buffer for storing said filtered white text image; a third filter for filtering said background image to produce a filtered background image and a third resultant buffer for storing said filtered background image; an image merging unit coupled to said first, second and third resultant buffers for combining said filtered black, white, and background images into an output image in said second resolution.
