IMAGE SIGNAL PRE-PROCESSING DEVICE USING CDF EQUALIZING FOR 3D IMAGE CONVERSION CAPABLE OF EASILY MAKING AN IMAGE, WHOSE BRIGHTNESS IS UNEQUALLY DISTRIBUTED, THREE-DIMENSIONAL

摘要

PURPOSE: An image signal pre-processing device using CDF equalizing for 3d image conversion is provided to distribute concentrated brightness onto the entire brightness area.;CONSTITUTION: An image signal pre-processing device generates Y image by RGB images(S10). The device generates an energy map by the Y image(S20). The device extracts a vertical connection line with the minimum energy value from the energy map(S30). The device adds a pixel energy average value or the minimum energy pixel to the vertical connection line on a left image(S40). The device moves a right image left after a reference location(S50).;COPYRIGHT KIPO 2012
