ABSTRACT:
An image processing circuit comprising plural line buffers is provided. Each line buffer stores pixel data of plural pixels as line data. A first image processing part performs a first image processing task on original image data provided from the exterior by using the line data stored in at least one of the line buffers. A second image processing part performs a second image processing task on the processed image data from the first image processing part by using the line data stored in at least one of the line buffers. A line buffer selector selectively connects the first image processing part and the second image processing part to any number of line buffers. An output path selector selects one of an output path that skips the second image processing task and an output path that performs the second image processing task.
