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.
