Abstract: 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 F1. The method includes the steps of receiving the first reference clock signal with the frequency F1 to generate and output a clock signal with a frequency F1nullN, proceeding a divided-by-P1 and a divided-by-P2 operations on the clock signal with a frequency F1nullN, respectively, to output a first output clock signal with a frequency F1nullN/P1 and a second output clock signal with a frequency F1nullN/P2, respectively. The value P2/P1 correlates 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.

Abstract: 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.

Abstract: 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.
