Abstract:
An adaptive image enhancement filter for receiving image data including a plurality of pixels and generating enhanced image data for driving a marking engine for each pixel within the image data, comprising:a template matching processor receiving an observation pattern including a target pixel and at least one pixel neighboring the target pixel, the template matching module comparing the observation pattern to a set of templates and generating a match identification signal; and a signal generation processor connected to receive the match identification signal and a marking process attribute signal, the signal generation processor including a plurality of sets of optimized signals, each set of optimized signals containing a plurality enhanced signals for driving the marking engine, the signal generation processor identifying one of the sets of optimized signals in response to the marking engine attribute signal and providing in response to the received match identification an enhanced signal from the identified set of optimized signals signal as enhanced image data for the target pixel.
