Patent number: 7542174Abstract: An image processing method for reducing jaggy effect, which is applied in an image output device, is provided. Firstly, a continuous tone image is generated, and continuous tone pixels are defined according to a first addressing space. Then, a halftone image is generated. After that, the continuous tone image is low-pass filtered to generate a low-pass filtered image. Next, determine whether a position of the low-pass filtered image whose density is approximate to a pre-determined density. If so, generate a set of second addressing space co-ordinates of a key point corresponding to the position. Then, a moving vector corresponding to the key point is generated so as to regulate the position of a display point of the halftone pixel. Afterward, output the display point according to the position after regulation.Type: GrantFiled: October 28, 2004Date of Patent: June 2, 2009Assignee: Qisda CorporationInventor: Hui-Jan Chien

Patent number: 7415163Abstract: An image noise reducing method that can properly reduce both block noise and mosquito noise without deterioration of the image quality is provided. The method includes creating a first luminance component image data with the boundaries of the blocks thereof smoothened, creating a second luminance component image data with its entirety smoothened from the first luminance component image data, creating edge image data by subtracting the second luminance component image data from the first luminance component image data, creating corrected edge image data by applying correction to the edge image data under given conditions, and creating third luminance component image data by adding the corrected edge image data to the second luminance component image data. For color-difference component image data, first color-difference component image data with its entirety smoothened is created from the color-difference component image data.Type: GrantFiled: November 23, 2004Date of Patent: August 19, 2008Assignee: Noritsu Koki Co., Ltd.Inventors: Noriyuki Nishi, Hisakazu Kuramoto, Takuma Suzuki, Minoru Yamamoto

Patent number: 7405845Abstract: Dot characteristic points are first extracted from M-level image data by the dot characteristic point extracting device. A dot area identifying device subsequently identifies a dot area based on the results of the extraction carried out by the dot characteristic point extracting device. When the image attribute determination is completed, a parameter setting unit sets N-level conversion parameters based on the results of the determination carried out by the dot area identifying device. Consequently, N-level conversion takes place using the N-level conversion parameters appropriate for a dot area. Therefore, N-level conversion in which the occurrence of moire is prevented may be carried out regarding dot areas.Type: GrantFiled: November 30, 2001Date of Patent: July 29, 2008Assignee: Minolta Co., Ltd.Inventor: Atsushi Ishikawa

Patent number: 7391920Abstract: If an edge is detected between each pair of two mutually adjacent pixels among three serially adjacent pixels in a digital image, a candidate pixel selection unit in an intermediate value pixel judgment unit selects a pixel located at the middle among the three pixels as a candidate pixel. A pixel value comparison unit compares the pixel values of the three pixels, which are used for selecting the candidate pixel, with each other. Only if the pixel values of the three pixels monotonically increase or monotonically decrease along the arrangement direction of the pixels, a judgment unit judges that the candidate pixel is an intermediate value pixel.Type: GrantFiled: November 3, 2004Date of Patent: June 24, 2008Assignee: Fujifilm CorporationInventor: Yuko Abe

Patent number: 7379210Abstract: It is intended to provide an image processing apparatus capable of precisely discriminating a halftone dot region and a figure such as a character arranged on the halftone dot region and applying appropriate image processing to the halftone dot region and the character separately. An isolated point discriminating section detects presence of an isolated point and detects a size of the detected isolated point. A temporary halftone dot region discriminating section 42 determines a temporary halftone dot region by counting the number of isolated point signals detected. Thereby, a region where isolated points concentrate is regarded as a temporary halftone dot region. An isolated point magnifying section 43 magnifies the detected isolated point signal to its original size so as to determine a magnified isolated point region. A halftone dot region restricting section 44 takes an AND computation results of the temporary halftone dot region and the magnified isolated point region.Type: GrantFiled: June 13, 2003Date of Patent: May 27, 2008Assignee: Minolta Co., Ltd.Inventors: Tomohiro Yamaguchi, Kazuhiro Ishiguro
