  • Patent number: 11919442
    Abstract: A vehicle interior lighting device includes a light source which is installed at an end of an instrument panel of a vehicle. Light emitted from the light source propagates from the instrument panel toward a door panel, and is projected on a surface of a door trim of the door panel. A decorative pattern element is installed on a light emitting side of the light source. As light from the light source passes through the decorative pattern element, the light can create a pattern on a surface of the door trim. Because the light source is installed on the instrument panel spaced from the door trim rather than on the door trim itself, light can be projected on a large area of the door trim. Furthermore, an impressive feature of a decorative pattern which changes in accordance with a door opening angle can be achieved.

  • Patent number: 9876965
    Abstract: A moving-image processing device (101) synthesizes a first moving image and a second moving image. In the first moving image, a first object is drawn, and accompanied by first-object depth information. In the second moving image, a second object is drawn, and accompanied by second-object depth information. A moving image generator (105) generates a third moving image in which the first moving image and the second moving image are synthesized. A clash determiner (103) serving as an interference determiner refers to the first-object depth information and the second-object depth information to determine whether the first object and the second object in the third moving image satisfy interference conditions. In cases when it is determined that the interference conditions are satisfied, a corrector (106) performs deforming transformation corresponding to correction of the shape of the trajectory of movement of the second object in three-dimensional space, thereby correcting the second moving image.

If it is determined that the interference conditions are satisfied, a corrector (106) corrects the second moving image by performing a non-deforming transformation in which the shape of the trajectory expressing movement in three-dimensional space over time is maintained.

  • Patent number: 9723225
    Abstract: A moving-image processing device (101) synthesizes a first moving image and a second moving image. In the first moving image, a first object is drawn, and accompanied by the anterior-surface depth of the first object. In the second moving image, a second object is drawn, and accompanied by the anterior-surface depth of the second object. A rear-surface-depth acquirer (102) acquires the rear-surface depth of the first object and the rear-surface depth of the second object. A clash determiner (103) functioning as an interference determiner refers to the anterior-surface depth and rear-surface depth of the first object to obtain an occupancy space which the first object can occupy, and refers to the anterior-surface depth and the rear-surface depth of the second object to determine whether the occupancy space and the second object drawn in certain frames of the second moving image satisfy interference conditions.

  • Patent number: 9374535
    Abstract: Provided is a moving-image processing device for determining interference between objects. A moving-image processing device (101) determines whether a first object drawn in a first moving image clashes with a second object drawn in a second moving image. The first moving image is accompanied by a first anterior-surface depth for the first object. The second moving image is accompanied by a second anterior-surface depth for the second object. A rear-surface depth acquirer (102) acquires a first rear-surface depth for the first object, and a second rear-surface depth for the second object.

  • Patent number: 9076036
    Abstract: A video search device for video searches in which a user specifies the position and orientation of an object that should appear in a video. A receiver receives input of a still image, two reference positions in the still image and two target positions in a video frame. An extractor extracts a reference image containing the two reference positions from the still image. A searcher searches for similar frame images in which local images similar to the reference image are depicted, from frame images in the video, traces movement tracks of two noteworthy pixels at start positions corresponding to the two reference positions in a local image when time advances or regresses from a similar frame image in the video, searches for a target frame image where the two movement tracks approach two target positions, and produces videos containing the similar frame image and the target frame image.

  • Patent number: 9058328
    Abstract: A search server includes an extracting unit that extracts a search target matching a search condition based on profile data, and a transmitting unit that transmits the search target to a user terminal. The search condition includes a first frequency of appearance for each of one or more specified topics specified by a user in a first specified period and a second frequency of appearance for each of the specified topics in a second specified period being later than the first specified period. The extracting unit extracts the search target where the frequency of appearance for each of the specified topics in a first search target period and a second search target period being later than the first search target period are identical or similar to the first frequency of appearance and the second frequency of appearance, respectively.
