摘要： A method and apparatus for detecting edges by which the detection of the edges of a natural image from an image obtained by mixing the graphic or text and the natural image is suppressed, to thereby stably detect edges of the graphic or the text, are disclosed. In this method, the differences in pixel value between the first pixel of sequentially input images and eight pixels adjacent to the first pixel are obtained. If all of the differences between the first pixel and the eight pixels adjacent to the first pixel are greater than a maximum threshold value or less than a minimum threshold value, the first pixel is determined to be an edge pixel. Likewise, determinations are made as to whether a second pixel, positioned adjacent the first pixel along a first dimension (for example to the left of the first pixel), is an edge pixel and whether a third pixel, positioned adjacent the first pixel along a second dimension (for example above the first pixel), is an edge pixel. Next, if at least one of the first pixel and the second pixel is determined as an edge pixel and if the difference between the first pixel and the second pixel is greater than the maximum threshold value, it is determined that the left edge of the first pixel exists. Also, if at least one of the first pixel and the third pixel is an edge pixel and the difference between the first pixel and the third pixel is greater than the maximum threshold value, it is determined that the upper edge of the first pixel exists.

摘要： A 2-dimensional non-linear interpolation system and method based on edge information includes an edge detector, an edge direction modifier, a near-edge coefficient generator, a filter coefficient generator and a non-linear interpolation unit. The edge detector detects edge information among pixels from a video signal applied through an input terminal. The edge direction modifier converts the edge information detected by the edge detector on the basis of a center point among peripheral pixels of an interpolation position and outputs modified edge information. The near-edge coefficient generator converts the coordinates of the interpolation position based on the modified edge information to generate a converted interpolation position, generates edge patterns corresponding to the converted interpolation position, and generates a plurality of 2-dimensional interpolation coefficients in response to predetermined one-dimensional non-linear interpolation filter coefficients. The filter coefficient generator generates the one-dimensional non-linear interpolation filter coefficients in response to the coordinates of the converted interpolation position, the edge patterns and predetermined one-dimensional filter coefficients. The non-linear interpolation unit multiplies data values associated with the peripheral pixels by the plurality of 2-dimensional non-linear interpolation coefficients to perform non-linear interpolation. Accordingly, even when a video image is magnified using non-linear interpolation, the resolution of a text or graphic image can be maintained without distortion of edges and aliasing.
