摘要： The present invention provides an image reducing system and method capable of retaining fine lines in a reduced image by reducing an original image and by quickly forming the reduced image with high quality. The method includes specifying positions of pixels of a reduced image in the original image according to reduction ratios, extracting a run of pieces of the same color information about the color of the pixels of the original image as a line, determining the line width of the extracted line and determining the line width after reduction in the reduction ratios based on the line width of the extracted line and calculating the centroid of the extracted line, and retaining the color information about the extracted line at a reduced pixel near the centroid on the basis of the centroid of the extracted line and the line width after reduction. The method further performs the step of determining the color information about each reduced pixel based on the retained color information.
