摘要 |
An image processing device (10) includes: a representative pixel value storage unit (12) which selects one of plural sub-pixels as a representative sub-pixel, and store, into a representative pixel value storage area, a representative pixel value which is a pixel value of the representative sub-pixel; and a sub-pixel value storage unit (13) which stores, into a sub-pixel value storage area, pixel values of sub-pixels other than the representative sub-pixel, wherein the sub-pixel value storage area stores one or more sets corresponding to N number of pixels, the one or more sets each including a pixel position and a pixel value of each sub-pixel other than the representative sub-pixel of a pixel at the pixel position, N being a natural number smaller than a total number of the plural pixels in the unit of processing for an edge determination unit (11). |

1. An image processing device for processing pixels in image data, wherein the unit size of the processing is a unit of processing including plural pixels, said image processing device comprising:
an edge determination unit configured to determine, for each of the plural pixels in the unit of processing, whether the pixel includes a predetermined edge; a representative pixel value storage unit configured to, for each of the plural pixels, select one of plural sub-pixels obtained by dividing the pixel, as a representative sub-pixel, and store, into a representative pixel value storage area, a representative pixel value which is a pixel value of the representative sub-pixel; and a sub-pixel value storage unit configured to store, into a sub-pixel value storage area, pixel values of two or more of the plural sub-pixels in each of pixels determined by the edge determination unit to include the predetermined edge, the two or more of the plural sub-pixels being other than the representative sub-pixel selected by the representative pixel value storage unit, wherein the sub-pixel value storage area stores one or more sets corresponding to N number of pixels, the one or more sets each including a pixel position and a pixel value of each sub-pixel other than the representative sub-pixel of a pixel at the pixel position, N being a natural number greater than zero and smaller than a total number of the plural pixels in the unit of processing for the edge determination unit. |
