  • Patent number: 8320669
    Abstract: In image processing in which each small area included in color image data, which is represented by C, M, Y, and K, is expressed by a predetermined number of representative colors, values of color parameters are obtained for a small area from the values of the color parameters for C, M, Y, and K for each pixel in the small area, so that the values of the color parameters have degrees of variation being compensated to become smaller in the group as the value for black becomes larger. One color parameter to be targeted is selected (#104) based on the degree of variation in the values of individual color parameters in the group. A reference value to be used for grouping the pixels is obtained based on the relationship between the values of the color parameter to be targeted in the group and the quantities of pixels in the group. Based on the reference value, the pixels are divided into groups (#106), and a representative color for each group is obtained (#109).

  • Publication number: 20120293693
    Abstract: An objective of the present invention is to provide a technique capable of generating a virtual viewpoint image without causing any visually uncomfortable feeling. In order to achieve this objective, a first image obtained by being captured from a first viewpoint at a first image capture time, and a second image obtained by being captured at a second image capture time different from the first image capture time are acquired. To each of pixels in a non-image capture area corresponding to a portion of a subject not captured in the first image of a first virtual viewpoint image that is generated in a pseudo manner based upon the first image and can be acquired by being captured from a first virtual viewpoint different from the first viewpoint, a pixel value is added in accordance with the second image.

  • Publication number: 20120294639
    Abstract: An image forming device includes: an image forming section, a fixing unit, an oscillation mechanism and a controller. The image forming section forms an image on paper. The fixing unit thermally fixes the image on the paper by using a fixing rotating member to pinch and convey the paper. The oscillation mechanism oscillates at least the entire fixing rotating member of the fixing unit in an axis direction thereof. The controller determines an oscillation quantity of the fixing rotating member based on rigidity of the paper in a state where the paper is pinched and conveyed by the fixing rotating member and another rotating member at the same time, and oscillates the fixing rotating member using the oscillation mechanism with the determined oscillation quantity. The controller determines the oscillation quantity of the fixing rotating member to be reduced as rigidity of the paper becomes lower.
