Abstract:
The present invention relates to an image processing method for converting a gray-level image into a binary image by using an image processing system. The gray-level image comprises a plurality of gray-level pixels arranged in a matrix format. The binary image comprises the same number of binary pixels arranged in the same manner as the gray-level image. The image processing system comprises a memory for storing programs and the gray-level and binary images, and a processor for executing the programs stored in the memory. The image processing method comprises two steps. The first step is to examine the gray-level pixels of the gray-level image so as to locate and define gray-level pixels with boundary characteristics as boundary points according to a predetermined boundary determination method, and to define gray-level pixels next to each of the boundary points as neighboring points according to a predetermined neighboring point determination method. The second step is to convert each of the boundary points and neighboring points of the gray-level image into a corresponding binary pixel according to a first pixel conversion method, and to convert each of the gray-level pixels other than the boundary points and neighboring points in the gray-level image into a corresponding binary pixel according to a second pixel conversion method to generate the binary image.
Abstract:
A touch panel is provided. The touch panel includes a resistance panel module and a detecting module. The resistance panel module includes a first conducting path and a second conducting path. When an event of multiple-point touching occurs, the first conducting path is electrically connected to the second conducting path. The detecting module is coupled to the touch panel. The detecting module detects a variation of the resistance value between the first conducting path and the second conducting path to estimate the event of multiple-point touching. Therefore, the variation of the resistance value can serve as an input signal of an interface between humans and machines to control an electronic device.
Abstract:
A digital camera has an image sensor system, a first compression system, a frame buffer, a first decompression system, and an image processing system. The image sensor system provides n pixels of initial image information. The n pixels each have m bits of intensity information of one color from three component colors. The initial image information is thus n×m bits in size. The first compression system compresses the n×m bits of the initial image information into r bits of secondary image information. The frame buffer is at least r bits in size for storing the secondary image information. The first decompression system decompresses the r bits stored in the frame buffer to provide tertiary image information. Finally, the image processing system accepts the tertiary image information to generate processed image information. The pixels of the processed image information each have intensity information for each color of the three component colors.

Abstract:
A method for compressing image data at a fixed rate and a device thereof is used for a scanning device capturing and generating image data. When the image data is scanned, the scanning areas of each color data are respectively selected to compress image data with a fixed rate. A decompression method is utilized which interpolates the decompressed data based on known color data in adjacent pixels.
