Description of the invention (5-1 Invention Rhyme) t Field and Background The present invention is a method and device for correcting scanned images, and is applied to optical scanners. The automatic correction method and device used to scan 2 tilts due to optical-mechanical problems. Precursor B. Background of the Invention: The optical-mechanical systems of optical scanners currently use adjustment jigs to adjust the level, left and right, and lens focal length ' Assembled in the body. Generally, when scanning documents, the Calibration paper is used as the calibration of the charge-coupled sensor (CCD) to detect the illumination. Freely when the optical-mechanical system is assembled in the body, It may cause errors or the scanner may be used for too long, or the track may be shifted due to excessive vibration during transportation, resulting in skewed or distorted scanned images, as shown in Figure 1. Figure 1 shows a scanned image Enlarged schematic diagram. A normal scanned document should be positive, represented by A (i, j). The leading edge of a skewed scanned image is represented by a black skewed line, and its area is represented by As (i, j). Skewed or When the real phenomenon occurs, even if it is readjusted, it is difficult to be effective. Because the condition of each unit is different, it cannot be handled uniformly, and even if it is sent to the customer service department for repair, it is difficult to completely improve. 5 — 2 Purpose and summary of the invention: This paper Standards are applicable to China National Ladder Standard (CNS) A4 specifications (210X29?

Description of the invention () Based on the above problems, the main purpose of the present invention is to propose a smart scanning device. With an automatic correction device, it can automatically correct the skewed image when the image is skewed, and effectively solve the image shift or distortion caused by the problem of the optical-mechanical system of the scanner. Another object of the present invention is to propose an automatic correction of the skew immediately. The method and device for scanning images are used to improve the quality of scanning and reduce the manpower and cost of maintenance. Based on the above-mentioned purpose, the present invention provides an automatic image correction method and device, which can automatically correct the problem caused by light and light. Distorted image caused by this method. The correction method and device first divide many segments in the memory to sequentially store the corrected pixels of different segments. The correction of pixels is judged according to the degree of distortion of the pixels. When the skew rate is larger than the edge length of one pixel, it indicates the beginning of another segment. The pixels in each column can be divided into many segments accordingly. The correction of pixels is calculated according to the skewed area ratio and becomes the corrected area. Whenever a row of pixels has been corrected, the corrected pixels will be output sequentially from the memory, and the method will be repeated to complete the correction of the entire image. The simple description of 5-3 An enlarged schematic diagram of an image that appears skewed before being scanned. FIG. 2 is a schematic diagram of a method for handling the situation of skew in the present invention. Circle 3 is a schematic diagram of the automatic correction method of the present invention.

Description of the invention (Figure 4 is the flow of the automatic calibration method of the present invention. Figure 5 is the automatic calibration device of the present invention. 〇 4 The detailed description of the invention is to solve the above problems. 'The present invention provides an intelligent image automatic correction method and device' whose main principle is to divide the skewed image into several regions horizontally according to the skewed image of Cheng Wan and only record each segment in the memory | The beginning and end of the Tuyin Temple 81 Jingya Biao. In a memory f, it is planned as a number of areas ± 4 'to record the shadow data and locations of the different sections. Then a circle is based on a reference point. The skew rate of the element is deduced. When the skew rate exceeds a set value, the figure is used as a horse [the starting pixel of the 5 segment 'and so on' until the completion of one μ of all shadow $ sections. In each-segment image data, The degree of infidelity of each pixel is used to calculate the area. After the calculation, the corrected image is stored in the memory, where the segment belongs. After completing a column of image correction, it will follow the order of the segments in the memory. Sequential rotation of the psychedelic and positive data "is explained in circle 2. If the normal scanned image is A (i, j), the skewed scanned image is As (i, j). Basically, the corrected image The prime AI (i, j) should be As (i, j) = A (i, j), or As (i, j)% A (i, j). When the degree of image distortion is too large, it will inevitably make the image The distortion of the pixels exceeds one or more circles. To facilitate the calculation of image correction, the pixels in a column must be segmented. When adjacent pixels A (i, j) and A (i + l , J) The skewness exceeds a paper standard applicable to the Chinese National Standard (CNS) A4 specification (210X297 male 4) j_.

Description of the invention (for each picture element, the circle element will be regarded as another section ^ L $, so complete a whole column of Segmentation. According to this segmentation method, A (i, j) can be eight. · The knife is divided into 5 sections: i = 1 to 6, 7 to 18, 19 to 30, 31 to 42, and η 3 to 50. The corrected image will be output from the 5th column, which is the skew distortion. The degree J is the average value of 1 ~ 8, that is, j = 5. Before performing the method of the present invention, it must be set before execution. Preparation, including dividing the memory into several blocks, in order to arrange the shadow silly tributary materials in the divided sections of the memory. In addition, two obvious The “reference point” is used as a double reference for the slope. For the calculation of the slope, refer to the Republic of China Patent No. 083901. Γ “The method of correcting the starting point of the file level in the image scanner” β The correction method of the present invention can be shown in Figure 3 As an example, explain the brother. Figure 3 shows the enlarged image of the first column of the first segment of Figure 2. ^ The dashed line in circle 3 indicates the normal ® prime coordinate arrangement; the skewed prime is tilted to the right and is represented by a solid line. The oblique line indicates the area to be corrected. ** The correction method of the present invention is to perform pixel-by-pixel correction one by one. Its correction principle is to compare with normal pixel coordinates. 'Leave the largest overlapping part as the base, and then add the area of four sides correction to the base.' It is the circle element after technical correction. Take the pixels of As (2,3) as an example. Its base is the block in the middle of As (2,3), and the areas ai, a ,, and a4 corrected by the four sides are marked with oblique lines. When the slope is less than the edge length of a pixel, the area of the corrected voxels should be considered in the sum of the base and its surrounding corrected parts "to indicate that the paper size is applicable to the Chinese family standard (CNS) A4 (210 parent 297) (Indecent) ------11 Μι -----m-^^ 1 1 =-I 1.-II ---- ^-1 * 1 HH ί- In · in (谙 Read the precautions on the back before (Fill in this page)
