Abstract: A method for correcting faded colors in aged photographs or film. The method automatically restores the color of the image by analyzing the color variance in the image and determining tonal curve for each channel. First, the interior of the image is selected and the image is portioned into sub-images. The variance of each sub-image is calculated, and the parameters are evaluated for correcting the entire image during scanning. This method will provide good color quality and preserve good density of the image.

Abstract: The invention relates to a method for detecting a tilted angle when it scans the document. First, the present invention scans the document to produce a first scanned data, and the fist scanned data is transformed into a binary image. The present invention determines whether the binary image comprises a graphic area. If the binary image comprises the graphic area, the present invention deletes the graphic area from the binary image to produce a deleted binary image; moreover, it uses a predetermined way, based on the deleted binary image, to calculate the tilted angle.

Abstract: A method of determining color composition of an image includes calculating an intensity value and a saturation value for each pixel of the image, comparing the calculated intensity and saturation values for each pixel with first and second predetermined threshold values, respectively, and labeling pixels with calculated intensity values above the first predetermined threshold value and calculated saturation values above the second predetermined threshold value as color pixels. Next, a mask is applied to the image and the number of color pixels selected by the mask is counted. If the number of color pixels selected by the mask is greater than or equal to a predetermined density value, the image is determined to be a color image.
