Abstract: The present invention relates to an auto focus method for obtaining a sharp image of two subjects. The auto focus method includes the following steps. Firstly, a pre-taken image is obtained by focusing on a first subject with an image capture device. Then, the pre-taken image is divided into a first area and a second area. According to image analysis, a first focusing lens step number for the first area and a second focusing lens step number for the second area are obtained. Then, a first image is obtained by focusing on the first area of the pre-taken image. By comparing the first focusing lens step number with the second focusing lens step number, it is discriminated whether a second image is captured or not.

Abstract: An interpolation method for processing digital pictures divides blank regions among the pixels equally into several squares. The interpolation parameter of each square corresponding to the sampling point is determined. These interpolation parameters are compressed and stored. When zooming a picture, the interpolating point is made sure to fall within a target square. The interpolation parameter is extracted according to the position of the target square. The brightness of the interpolating point is computed according to the interpolation parameter and the brightness of the sampling point.

Abstract: A method of repairing scratches in a digital image includes counting the number of abnormal pixels among neighboring pixels of a selected pixel. The selected pixels that are surrounded by abnormal pixels in a number greater than a predetermined value are designed as particular pixels. An area surrounding each particular pixel is divided into a plurality of blocks. Furthermore, brightness difference between two of the blocks are calculated. Scratch pixels are found from the particular pixels based on brightness difference between blocks. Then, an area surrounded by scratch pixels are subdivided and filled up. Thereby, the scratch pixels can be precisely found and repaired without the need of hardware.

Abstract: A method of photo/text separation using path frequency of pixel intensities is disclosed. It divides an original image into n*n pixel blocks and records the path conditions satisfied by the intensities of consecutive two pixels. From the statistical analysis of the path appearance frequency, the method determines the text/photo types in the pixel block, thereby determining the output type of the whole original image.

Abstract: A method of separating text and graphs in digital image data is used to separate digital image data into graph data and text data. According to a default separating parameter, the digital image data are partitioned into several operating matrices. One then sets a default crossing reference level for comparison analyses to compare adjacent pixel units in each operating matrix. When the digital characteristic value of a pixel unit is greater than the default crossing reference level and the digital characteristic value of its one adjacent pixel unit are smaller the default crossing reference level, the operating matrix is given a weight. Afterwards, all the weights are added up to give a weighted statistical value, which eventually is used to separate the graph data from the text data.

After an image input device reads a document, the pixel information and the pixel allowed error range are compared to determine whether the document is a color or black-and-white (BW) one. If it is a BW document, the image file is directly converted into a monochromic and grey-level one and stored in 8-bit or even 1-bit format, thereby reducing the storage space occupied by the image file.
