Abstract: An apparatus and method for improving qualities of motion and still images to be output in a mobile communication terminal. An error-reflected-value table is provided to reduce a computation amount while applying an error diffusion process. The table includes quantization-error-reflected values pre-computed according to maximum values of quantization errors and error-reflected ratios of neighboring pixels. When quantization errors of a specific pixel of an original image selected in a process procedure are computed, error-reflected values of neighboring pixels are determined. Pixel-by-pixel error values are stored by accumulating error-reflected values related to pixels. When error-reflected values of neighboring pixels around all the pixels of the original mage are completely computed, an image in which quantization errors are diffused is generated when the error-reflected values are added on a pixel-by-pixel basis. The error-diffused image is stored and displayed in place of the original image when a user makes a request.

Abstract: Pixels in a YUV format including a Y component representing luminance and U and V components representing chrominance are converted into a RGB format including R, G, and B components respectively representing red, green, and blue colors in order to display images on a video display device such as a CRT (Cathode Ray Tube) or a LCD (Liquid Crystal Display). The present invention relates to an apparatus and a method for converting the pixels from the YUV format to the RGB format using color look-up tables with a small memory capacity. The R component is obtained from the first and second color look-up tables using the Y and V components as indexes, and the G component is obtained from the first, third, and fourth color look-up tables using the Y, U, and V components as indexes, and the B component is obtained from the first and fifth color look-up tables using the Y and U components as indexes.

Abstract: A method of manufacturing a flash memory cell in which an ion implantation process is performed before a cleaning process for etching a protrusion of a trench insulating film to a nipple shape. As a result, the etch rate at a portion except for portions in which a moat will occur along the trench insulating film is increased. Therefore, generation of the moat in the trench insulating film can be prevented and spacing of the floating gate can be optimized.
