  • Publication number: 20190114823
    Abstract: There are provided an image generating apparatus, an image generating method, and a program for generating an image that allows each of the users sharing a virtual space to see what the ether users are looking at. A virtual space managing section (126) arranges a fixation point object indicative of a fixation point at a position away from a first viewpoint in a first visual line direction passing through the first viewpoint arranged in a virtual space, the first visual line direction corresponding to the attitude of a first head-mounted display. A frame image generating section (128) generates an image indicating how things look from a second viewpoint in a second visual line direction corresponding to the attitude of a second head-mounted display, the second viewpoint being arranged in the virtual space in which the fixation point object is arranged.

  • Patent number: 10244238
    Abstract: A tile image sequence obtained by dividing a frame into a predetermined size is further divided into another predetermined size on an image plane to generate a voxel (for example, a voxel. If a redundancy in a space direction or a time direction exists, then data is reduced in the direction, and sequences in the time direction are deployed on a two-dimensional plane. Voxel images are placed on an image plane of a predetermined size to generate one integrated image. In a grouping pattern which exhibits a minimum quantization error, pixels are collectively placed in the region of each voxel image for each group (integrated image). The integrated image after the re-placement is compressed in accordance with a predetermined compression method to generate a compressed image and reference information for determining the position of a needed pixel.

  • Publication number: 20190057537
    Abstract: Regions 150 and 152 on a texture image plane 140 that correspond individually to pixels 146 and 148 representing an image on a texture image mapping target surface 144 in a screen plane 142 on which to define a display image are determined using predetermined transformation equations. The number of sampling points and their distribution are determined for the determined region in accordance with its shape and its size. Texel values in the determined region are then sampled. An average of the sampled values is acquired as the value of each of the original pixels 146 and 148.

  • Patent number: 10210629
    Abstract: A detection area is set in a three-dimensional space in which a subject exists. When an actual hand enters the detection area, coordinate points (white and black dots) represented by pixels making up a silhouette of the hand in a depth image enter the detection area. In the detection area, a reference vector is set that shows the direction which the hand should face relative to the shoulder as a reference point. Then, an inner product between two vectors, a vector from the reference point to each of coordinate points and the reference vector, 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.
