Abstract: An image processing device appropriately extracts an entire object from an image even if the object is not completely included in an initial region designated by a user. The image processing device includes: a designation unit designating a position on the image; a setting unit setting a first combination consisting of a first object region candidate and a first background region candidate, and a second combination; a histogram generation unit generating a normalized color histogram of each of the regions; a similarity calculation unit calculating a similarity regarding each of the combinations; and a selection unit configured to select a combination from the first and second combinations so that the selected combination has the similarity lower than the similarity of the non-selected combination.

Abstract: A device that is not necessarily high in performance, includes: a standard information obtaining unit configured to obtain standard information including a type of drawing process that could be used for computer graphics and a feature of the shape of polygon; a drawing information obtaining unit configured to obtain drawing information including information indicating the type of drawing process used for the actual computer graphics and information indicating the shape of polygon; a simplification judging unit configured to judge whether the type of the drawing process and the shape of the polygon indicated by the drawing information satisfy the standard indicated by the drawing standard information; a polygon simplifying unit configured to simplify the polygon by reducing vertices composing the polygon when said simplification judging unit judges that the standard is satisfied; and a drawing unit configured to execute computer graphics process using the polygon whose vertices are reduced, in order to achieve

Abstract: An image synthesis output apparatus is capable of saving power in the stage of obtaining a synthetic image of a plurality of images. In the apparatus, during a period when either of first and second input images is updated within a first predetermined period, a multi-layer image synthesis section synthesizes these input images and outputs a synthetic image to an LCD display panel. If neither of the first and second input images are updated within the first predetermined period, the multi-layer image synthesis section also writes the synthetic image in a synthetic- image storage section. If the first and second input images are not updated and a second predetermined period elapses after the first predetermined period, then without synthesizing the first and second input images, the multi-layer image synthesis section reads the synthetic image and outputs it to the LCD display panel.

Abstract: A reception apparatus includes: a reception unit for receiving the scrambled content, the scrambled content being scrambled so that a predetermined unit of scrambled content is descrambled using a descrambling key corresponding to the predetermined unit of scrambled content, and at least one piece of storage information in which a list including all descrambling keys used for descrambling the scrambled content is embedded; storage unit for storing the received scrambled content and the storage information; list extraction unit for extracting the list from the stored storage information; descramble processing unit for extracting the predetermined unit of scrambled content from the stored scrambled content, extracting a descrambling key corresponding to the predetermined unit of scrambled content from the extracted list, and descrambling the extracted predetermined unit of scrambled content using the extracted descrambling key; and reproduction unit for reproducing the predetermined unit of descrambled content

Abstract: An image synthesis output apparatus is provided which is capable of saving a power consumption in the stage of obtaining a synthetic image of a plurality of images. In this image synthesis output apparatus, during an ordinary period when either of first and second input images which are stored in an input-image storage section is updated within a first predetermined period, a multi-layer image synthesis section synthesizes these input images and outputs a synthetic image to an LCD display panel. If neither of the first and second input images are updated within the first predetermined period, the multi-layer image synthesis section not only outputs the synthetic image but also writes it in a synthetic-image storage section.
