Embodiment Construction

[0032] Some embodiments of the present invention are described in detail as follows. However, the invention can be practiced broadly in other embodiments than those described in detail, and the scope of the invention is not limited, which is to be determined by the scope of the claims.

[0033] figure 2 It is a flowchart for illustrating the method for correcting image data according to the disclosure of the present invention. Step 10 represents scanning a reference white (white standard plate) to obtain first image data before scanning the document. Next, in step 11, a calculation method is used to generate shading curve, noise level, and brightness data, wherein the above-mentioned data are all corresponding to each sensing element, The sensing component may be a charge-coupled device (CCD; charge-coupled device). Next, step 12 is the main characteristic step of the present invention, the color attenuation curve is backfilled into the calibration memory and stored in the...

Abstract

The present invention relates to a method of adjusting images by means of calibration data parameters, that is, a method of judging to obtain the best image output quality, the method includes scanning a reference white to obtain an image data before scanning a document, and then, by means of The image data is calculated to generate a shading curve, noise level and luminance data corresponding to each sensing component, and then, the shading curve or standard value is backfilled and input into the calibration database, and then, Then use the scanning device to scan the file to obtain an image data corresponding to each sensing component, and read the color fading curve in the calibration database at the same time, and then use a judgment method to judge the distance between two adjacent pixels If the difference is less than the standard value, the two adjacent pixel values ​​are averaged and the average value is output; otherwise, the pixel value at the position is output, and finally the corrected image data is output.

Description

technical field [0001] The present invention relates to an image capture device in a scanning device, in particular to a method for reducing image noise during scanning by using a color attenuation curve, that is, a method for adjusting an image by means of correction data parameters. Background technique [0002] The traditional color image reading device scans an original placed on a transparent scanning platform made of a glass plate, in which a light source is used to project light on the original surface, and by receiving the reflected light from the original surface to capture The image on the original surface. When capturing a color image, the image reading device resolves the reflected light into three primary colors, namely red (R), green (G) and blue (B), and guides the three primary colors to a photoelectric converter, such as A charge-coupled device (CCD) is used to convert the analog signals of the three primary colors of light. The analog signals of the three...
