摘要： We describe an apparatus and method for decoding a SECAM chrominance signal. The apparatus may include a band-pass filter to separate the chrominance signal from the composite video baseband signal. A down-mixer down mixes the chrominance signal from a high to a low frequency band to generate two signals having a substantially 90° phase difference. A cloche filter filters the two signals. A differentiator differentiates the cloche filtered signals. A multiplier squares each differentiated signal. An adder sums the squared result while a square root takes the square root of the sum.

摘要： Provided is an apparatus for improving the sharpness of an image. The apparatus includes an edge detector, an effective edge judging unit, an effective edge classifying unit, an isolated edge judging unit, and a 2-D HPF applying unit. The edge detector calculates an edge value using brightness relation with neighboring pixels with respect to each of pixels of an input image.

The isolated edge judging unit judges an isolated edge pixel included in an isolated edge. The 2-D HPF applying unit applies a first 2-D HPF to the weak edge pixels, and applies a second 2-D HPF to the strong edge pixels to generate edge strengthening values. The edge strengthening value applying unit adds the edge strengthening values to brightness values of the respective pixels of the input image.
