  • Publication number: 20170011519
    Abstract: A detection area 112 is set in a three-dimensional space in which a subject exists. When an actual hand enters the detection area 112, coordinate points (white and black dots) represented by pixels making up a silhouette 114 of the hand in a depth image enter the detection area 112. In the detection area 112, a reference vector 126 is set that shows the direction which the hand should face relative to the shoulder as a reference point 122. Then, an inner product between two vectors, a vector from the reference point 122 to each of coordinate points and the reference vector 126, is calculated, followed by comparison between the inner products. Positions of coordinate points whose inner products are ranked high are acquired as the position of tips of the hand.

  • Patent number: 9542755
    Abstract: An image acquisition section of an information processor acquires stereo images from an imaging device. An input information acquisition section acquires an instruction input from a user. A depth image acquisition portion of a position information generation section generates a depth image representing a position distribution of subjects existing in the field of view of the imaging device in the depth direction using stereo images. A matching portion adjusts the size of a reference template image in accordance with the position of each of the subjects in the depth direction represented by the depth image first, then performs template matching on the depth image, thus identifying the position of a target having a given shape and size in the three-dimensional space. An output information generation section generates output information by performing necessary processes based on the target position.

  • Patent number: 9516310
    Abstract: Frames of a moving image are configured as a hierarchical structure where each frame is represented with a plurality of resolutions. Some layers are set as original image layers, and the other layers are set as difference image layers in hierarchical data representing a frame at each time step. In the case that an area is to be displayed in the resolution of the difference image layer, to respective pixel values of a difference image of the area, respective pixel values of an image of a corresponding area retained by the original image layer of lower resolution, the image enlarged to the resolution of the difference image layer, are added. A layer to be set as a difference image layer is switched to another layer as time passes.

  • Patent number: 9460486
    Abstract: Links are set among three hierarchical data and one moving image data. When a display area overlaps with a first link area while an image is being displayed by using first hierarchical data, switching to display by use of the 0-th hierarchical level of the second hierarchical data is made. When the display area overlaps with a second link area while an image is being displayed by using the second hierarchical data, switching to display by use of the 0-th hierarchical level of the third hierarchical data is made. The link destination of another link area is the moving image data and moving image reproduction is started as a result of zoom-up of this area. The hierarchical data are held on the client terminal side and the data existing on the other side of a switching boundary are transmitted to the client terminal in a data stream format.

  • Patent number: 9460337
    Abstract: An image storage section 48 stores shot image data with a plurality of resolutions transmitted from an imaging device. Depth images 152 with a plurality of resolutions are generated using stereo images with a plurality of resolution levels from the shot image data (S10). Next, template matching is performed using a reference template image 154 that represents a desired shape and size, thus extracting a candidate area for a target picture having the shape and size for each distance range associated with one of the resolutions (S12). A more detailed analysis is performed on the extracted candidate areas using the shot image stored in the image storage section 48 (S14). In some cases, a further image analysis is performed based on the analysis result using a shot image with a higher resolution level (S16a and S16b).

  • Patent number: 9253480
    Abstract: A viewpoint detection unit detects a user viewing a stereoscopic image, including a parallax image of a subject as viewed from a predetermined position defined as a reference view position, and tracks a viewpoint of the detected user. A motion parallax correction unit determines, if a speed of movement of the viewpoint becomes equal to or higher than a predetermined level, an amount of motion parallax correction for the parallax image, on the basis of an amount of movement of the viewpoint, so as to generate a stereoscopic image corrected for motion parallax, generates, if the speed of movement of the viewpoint subsequently becomes lower than a predetermined level, a stereoscopic image by changing the amount of motion parallax correction in steps until the parallax image return to parallax images as seen from the reference view position.
