  • Patent number: 8351809
    Abstract: When glossiness in an area designated by a user was adjusted, the glossiness adjustment was achieved by exchanging a plurality of toners having different glass transition points. Thus, the user was required to select an appropriate toner when the glossiness in the area designated by the user was adjusted. Further, the user took some time or effort to set the selected toner every glossiness adjustment. In the present invention, how to adjust the glossiness in the area designated by the user is obtained as mode information and on the basis of the obtained mode, control is effected so that a transparent image is selectively formed in the area designated by the user or an image formable area except for the area designated by the user.

  • Patent number: 8351097
    Abstract: Erroneous determination of an image caused by color shift is prevented. Image data is divided in a sub-scanning direction into a first region where color shift hardly occurs and a second region where color shift easily occurs. There are detected a first color line drawing extending in a main-scanning direction in the first region, a second color line drawing extending in the main-scanning direction and having a width larger than that of the first color line drawing in the second region, and a third color line drawing extending in the sub-scanning direction in the image data. On the basis of the detected first, second, and third color line drawings, it is determined whether a document is a color document or not.

  • Patent number: 8350868
    Abstract: A method of compositing a plurality of graphic objects with a compositing buffer, is disclosed. The plurality of graphic objects forming a group is attenuated by group opacity and is composited from a top object to a bottom object. Based on a first mask and the group opacity, a second mask is generated. The first mask stores a remaining possible contribution for further graphic objects below and including the plurality of graphic objects. The plurality of graphic objects in a top down order is processed. In particular, for each graphic object of the plurality of graphic objects: (a) a contribution value for the graphic object using the second mask is determined, the contribution value representing a contribution of the graphic object to the compositing buffer; (b) a colour value of the graphic object is composited with the compositing buffer using the contribution value; and (c) the second mask is updated using the contribution value. The first mask is then updated using the second mask and the group opacity.
