System for processing a digital image using two or more defined regions

Abstract

System for processing a digital image using multiple regions where each of the multiple regions is defined using a portion of the digital image. In addition, a top margin, a bottom margin, a left margin, and a right margin are defined to include margin pixels for each of the multiple regions of the digital image. Margin pixels are defined as neighboring pixels for a region of the digital image and may contain pixels that are part of the digital image, part of the region of the digital image, and/or newly generated pixels. Various techniques such as on the fly generation or using a predetermined process for video data information generation, such as replication or using a fixed color, may be used to generate the margin pixels. Each of the multiple regions is processed with its margin pixels to create a new quadrilateral digital image that is completely processed and/or scaled. The appropriate portion of the processed quadrilateral digital image is displayed using a display region of an electronic display panel having multiple display regions. The concatenation of the displayed portions of the processed quadrilateral digital images produces the original digital image using the electronic display panel.
