20130135439 | STEREOSCOPIC IMAGE GENERATING DEVICE AND STEREOSCOPIC IMAGE GENERATING METHOD - A stereoscopic image generating device includes: a correction parameter calculating unit that calculates correction parameters based on a plurality of pairs of feature points corresponding to the same points on the object, from the first image and a second image photographing the object; a correction error calculating unit that, for each pair of feature points, corrects the position of the feature point on at least one image, using the correction parameters, and calculates the amount of correction error; a maldistribution degree calculating unit that finds the degree of maldistribution of feature points; a threshold value determining unit that determines a threshold value such that the threshold value is smaller when the degree of maldistribution increases; and a correction unit that, when the amount of correction error is equal to or lower than the threshold value, corrects the position of the object in the images using the correction parameters. | 05-30-2013 |
20130147918 | STEREO IMAGE GENERATION APPARATUS AND METHOD - There is provided a stereo image generation apparatus which extracts a plurality of sets of feature points from each image of a subject formed in a left-half area and a right-half area captured using a stereo adapter such that feature points in each set correspond to the same one of points on the subject. The apparatus then calculates a set of correction parameters based on the sets of feature points and an evaluation value indicating a degree of likelihood of being correct feature point for a point with respect to a corresponding feature point extracted. For a given feature point of interest extracted from the one of the left-half and right-half areas, the evaluation value is high in a possible shifting area within which image shifting may occur due to distortion caused by the structure of the stereo adapter and the mounting potion error of the stereo adapter. | 06-13-2013 |
20130155055 | DISPLAY DEVICE, DISPLAY METHOD, AND RECORDING MEDIUM - A display device includes a memory and a processor coupled to the memory, wherein the processor executes a process including acquiring user information including a parallax amount, counting the number of users from each piece of the user information and generating a display schedule indicating timing of opening/closing of first and second shutters of each pair of glasses with shutters of each user on the basis of the number of users; adjusting data of a plurality of stereo images, included in image information, each of which includes a pair of a first image and a second image according to a parallax amount of each user included in each piece of the user information, controlling opening/closing of each of the first and second shutters of the each pair of glasses with shutters on the basis of the display schedule, and outputting image information adjusted by the adjustment unit. | 06-20-2013 |
20130155200 | STEREOSCOPIC IMAGE GENERATING DEVICE AND STEREOSCOPIC IMAGE GENERATING METHOD - A stereoscopic image generating device includes: a brightness calculation unit that, on an image that is photographed using a stereo adapter, obtains the brightness representative value of the first area where neither of two beams from the object is incident; a threshold value determining unit that obtains a threshold value based on the brightness representative value; and an object area extracting unit that extracts two sets of pixels having brightness value higher than the threshold value on the image, as a second area where one of the two beams is incident and a third area where the another of the two beams is incident, and produces a stereoscopic image by a pair of a first partial image that is cut out from the second area, and a second partial image that is cut out from the third area. | 06-20-2013 |
20130258461 | 3D DISPLAY DEVICE AND METHOD - A 3D display device that includes: a first optical section of focal distance f1 provided with a group of small lenses arrayed along a specific direction; and a second optical section of focal distance f2 that converges N beams of parallel light that are emitted from the first optical section and hit the individual small lenses by converging so as to offset the N beams from an optical axis. A distance d1 between the first optical section and the second optical section satisfies f2−f1≦d1≦f2 and a viewing distance d2 from the second optical section satisfies d2≈f2. | 10-03-2013 |
20140233100 | IMAGE DISPLAY APPARATUS AND IMAGE DISPLAY METHOD - A display displays a composite image including element pixels. Each element pixel is formed by arranging, in a direction, pixels respectively extracted from images having different viewpoints. A first optical element includes lenses arrayed in the direction to correspond to the element pixels and emits in parallel light rays emitted from pixels respectively included in the element pixels, for a particular image. A second optical element condenses the light rays. An output circuit selects a pixel of the particular image which is included in a particular element pixel and outputs its pixel value to the display. At this time, a pixel more distant from an optical axis of the second optical element along the direction in the particular image is selected as a distance between the first and second optical elements becomes smaller than a focal length of the second optical element. | 08-21-2014 |
20150077523 | STEREO IMAGING APPARATUS AND STEREO IMAGE GENERATING METHOD - A stereo imaging apparatus includes: an imaging unit which generates an image; a stereo adapter which is mounted on the front of the imaging unit, and splits light from a subject into a first light flux and a second light flux along a parallax direction and guides the first and second light fluxes so that the first and second light fluxes are incident side by side on the imaging unit in a direction perpendicular to the parallax direction; and a stereo image generating unit which, based on the image, generates stereo images. The stereo image generating unit includes: a dividing unit which divides the image into two sub-images along the direction perpendicular to the parallax direction; a horizontal direction correcting unit which corrects any rotation of the subject in the two sub-images; and a trapezoidal distortion correcting unit which corrects any trapezoidal distortion of the subject in the two sub-images. | 03-19-2015 |
20150281674 | STEREO ADAPTER AND STEREO IMAGING APPARATUS - A stereo adapter includes first and second reflecting surfaces disposed in a front of an imaging unit along a direction perpendicular to a parallax direction, a third reflecting surface disposed further away from the imaging unit than the first reflecting surface along the parallax direction, and a fourth reflecting surface disposed further away from the imaging unit than the second reflecting surface along the parallax direction and on an opposite side of the third reflecting surface. Each reflecting surface is rotated by a predetermined angle from an entrance pupil plane or an object plane around a first axis orthogonal to the parallax direction and the optical axis and is tilted such that a ray in parallel to the optical axis when entry forms an angle of a quarter of a vertical angle of view of the imaging unit to the optical axis when leaving from the stereo adapter. | 10-01-2015 |
