Abstract: When a head-mounted display acquires data of a display image generated on the basis of position/posture information of a head of a user at time and given a distortion corresponding to the distortion of an eyepiece lens, the head-mounted display corrects the image on the basis of position/posture information of the head at time t for display. Then, the head-mounted display corrects chromatic aberrations on the basis of actual distortion coefficients of the lens, and outputs the image to a display panel.

Abstract: Content data of a display target is acquired in accordance with a user's operations and is used to determine a configuration of a display image. Of the regions to be rendered using fonts in the display image, the region in which a character is to be displaced by a very small amount is determined. The characters targeted for displacement are rendered while being displaced over time in accordance with predetermined displacement rules. The characters not targeted for displacement are rendered in a reference position. With all characters rendered, the display image is completed and output. The processes of S12 to S24 are repeated until display is terminated.

Abstract: In a calibration apparatus, a captured image acquisition unit acquires data of an image of a calibration chart captured by a fish-eye imaging apparatus. A distortion correction unit makes an assumption of a parameter of the imaging apparatus, takes into account a projection system to make a correction, and adjusts the parameter until an image of the original chart is obtained. A pseudo image drawing unit uses model data of a chart to draw a pseudo captured image. A point-of-view adjustment unit compares the pseudo image and the captured image and adjusts a point-of-view position of a virtual camera according to a difference between positions of markers or intervals of patterns to specify a position of the imaging apparatus.

Abstract: An image generation device divides a distorted-image plane into pixel blocks in order to generate a distorted image in consideration of the distortion and chromatic aberration of an eyepiece. In the plane of a source image, the image generation device determines individual RGB sample positions included in the pixel blocks, sets a bounding rectangle containing the individual RGB sample positions, and determines, for example, computation target pixels corresponding to the bounding rectangle. The image generation device calculates the pixel values of, for example, the computation target pixels, interpolates and samples the calculated pixel values, and regards the results of interpolation and sampling as the pixel values of the distorted image.

Abstract: An image generating apparatus directly draws, by using scene data, a distortion image generated by giving common distortion to primary colors of R, G, and B, and transmits the distortion image to a head mounted display in an order of drawn pixel sequences. The head mounted display acquires color information from positions different for each of R, G, and B and dependent on chromatic aberration of an ocular lens in partial data of the distortion image stored in a line buffer. In this manner, the image generating apparatus generates partial data, each having different distortion, for R, G, and B, respectively, and immediately outputs the generated partial data to a display panel.

Abstract: A captured image acquisition section 50 acquires, from an imaging apparatus 12, data of a polarized image obtained by capturing a target object and stores the data into an image data storage section 52. A region extraction section 60 of a target object recognition section 54 extracts a region in which a figure of the target object is included in the polarized image. A normal line distribution acquisition section 62 acquires a distribution of normal line vectors on a target object surface in regard to the extracted region. A model adjustment section 66 adjusts a three-dimensional model of the target object stored in a model data storage section 64 in a virtual three-dimensional space such that the three-dimensional model conforms to the distribution of the normal line vectors acquired from the polarized image to specify a state of the target object.

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.
