A method for synthesizing a clock signal with multiple frequency outputs for use in a converter for converting a non-interlacing scan data into an interlacing scan data is disclosed. The converter provides a first reference clock signal with a frequency FThe method includes the steps of receiving the first reference clock signal with the frequency Fto generate and output a clock signal with a frequency F&#xd7;N, proceeding a divided-by-Pand a divided-by-Poperations on the clock signal with a frequency F&#xd7;N, respectively, to output a first output clock signal with a frequency F&#xd7;N/Pand a second output clock signal with a frequency F&#xd7;N/Prespectively. The value P/Pcorrelates to a ratio of the pixel number of a horizontal scan line in the non-interlacing scan data to that in the interlacing scan data. In addition, a clock signal synthesizer with multiple frequency outputs is also disclosed.

A method for processing an image to convert a non-interlacing scan data into an interlacing scan data is disclosed. The method includes the steps of receiving a non-interlacing scan data, the non-interlacing scan data including plural pixels, replacing a color space value of a selected one of the pixels in the non-interlacing scan data with a combination of color space values of the selected one pixel and at least one adjacent pixel to obtain a blurringly filtered non-interlacing scan data, scaling the blurringly filtered non-interlacing scan data according to a specific algorithm, and converting the blurringly filtered non-interlacing scan data into an interlacing scan data. An image-processing device for converting a non-interlacing scan data into an interlacing scan data is also disclosed. The device includes a blurring filter, a scaler and a converter.

An adaptive deflicker method for use in converting a non-interlacing scan data into an interlacing scan data is disclosed. The method includes the steps of receiving a non-interlacing scan data, wherein the non-interlacing scan data includes plural scan lines, proceeding a deflicker operation on an edge line of the non-interlacing scan data, exempting a non-edge line of the non-interlacing scan data from the deflicker operation, and converting the non-interlacing scan data into an interlacing scan data. In addition, an adaptive deflicker filter for use in converting a non-interlacing scan data into an interlacing scan data is also disclosed. The adaptive deflicker filter includes an edge-line detector and a deflicker filter.

A clock generating apparatus is provided for producing an output clock signal responsive to a source clock signal with a source frequency and a reference clock signal with a reference frequency. The clock generating apparatus includes a counting sequence generator, a measuring value generator and a ratio counter. The counting sequence generator is used for outputting a series of counting values in response to a triggering signal with a specified period determined by the source frequency of the source clock signal and a predetermined counting value. The measuring value generator generates a measuring value by operating the series of counting values according to a predetermined formula. The ratio counter produces the output clock signal with a frequency determined by the source frequency of the source clock signal and the measuring value.
