  • Patent number: 8351691
    Abstract: A method of text extraction in color compound documents is described. The method connects similarly colored pixels of an image of a color compound document into connected components (CCs); classifies each CC as either text or non-text; refines the text CC classification for each text CC using global color context statistics; groups text CCs into text blocks; recovers misclassified non-text CCs into a nearby text block; and removes extraneous CCs from each text block using local color context statistics to thereby provide the extracted text in the text blocks. Also described is a method of locating graphics objects in a color compound document image.

  • 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: 8348401
    Abstract: A turning operation of a head set lever is completed, and a printing head can be detached from a carriage part. By the above-described turning operation of the head set lever, a supply port insertion and extraction part connected via a link slides, a needle pipe of the supply port insertion and extraction part is brought into a state of being the farthest from the printing head, and a needle insertion and extraction lever is brought into a state in which it moves under a case wall. Thereby, an operator cannot turn only the needle insertion and extraction lever when the head set lever is in an opened state. In this manner, when the head set lever is in the opened state, the operation of the needle insertion and extraction lever, which is used for connection of the supply port insertion and extraction part to ink supply port, is restricted.

  • 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.
