Patent number: 7663779Abstract: When the size output for an image is equal to or smaller than a predetermined value (e.g., index printing), a printing apparatus performs an image expansion/reduction process by using an interpolation method whereby high speed processing is enabled while an inferior image quality is provided, or when the output size is greater than a predetermined value (e.g., the normal printing of a single sheet), employs an interpolation method for a high quality image to perform the expansion/reduction. Further, when the output image size is equal to or smaller than the predetermined value, the printing apparatus 1 skips the noise reduction process and the sharpening process to increase the processing speed.Type: GrantFiled: August 14, 2003Date of Patent: February 16, 2010Assignee: Fuji Xerox Co., Ltd.Inventors: Takashi Nagao, Noriaki Seki, Yoshiharu Hibi, Masaru Okutsu, Makoto Sasaki
