Abstract:
1. An image processor comprising an image processing circuit image-processing image data input therein and a main memory receiving and temporarily storing transferred said data processed in said image processing circuit, wherein said image processing circuit has a temporary storage area temporarily storing pixel data of a plurality of lines of said image data, image dividing means dividing said image data into divided image data storable in said temporary storage area, single pixel processing means executing image processing on said divided image data in units of single pixels and multiple pixel processing means executing image processing in units of multiple pixels after said temporary storage area stores said divided image data processed in said single pixel processing means, thus creating processed divided image data, and said main memory has a first buffer area storing first processed divided image data continuously processed in said single pixel processing means and said multiple pixel processing means among said divided image data, a second buffer area storing second processed divided image data processed in said single pixel processing means among said divided image data and a third buffer area storing data obtained by processing said second processed divided image data read from said second buffer area in said multiple pixel processing means, said image processor further comprising image combining means combining said first processed divided image data stored in said first buffer area and said data stored in said third buffer area with each other.
