  • Patent number: 9456206
    Abstract: A phase error detection unit measures a phase error between an external synchronization signal and a spectacles control signal that is fed back, more specifically, a discrepancy between vertical synchronization timing and shutter opening/closing timing, that is, jitter. A timing correction unit corrects the shutter opening/closing timing, using the measured jitter. Specifically, a parameter indicating the corrected shutter opening/closing timing is written to a storage unit. The storage unit stores a parameter used to generate the spectacles control signal, for example, the parameter indicating the shutter opening/closing timing. A signal generation unit generates the spectacles control signal, using the parameter stored in the storage unit. A frequency divider divides the frequency of the spectacles control signal by n.

  • Patent number: 9453716
    Abstract: Provided are a method for measuring tool dimensions and a measurement device, whereby if a machine tool (10) cannot fit the overall outline of a tool (20) inside the field of vision (V) for an image from an imaging device (33), the field of vision (V) of the imaging device (33) is moved by relatively moving the imaging device (33) and the tool (20). In addition, the imaging device (33) can follow the outline (54) of the tool (20) by moving the field of vision (V), because the movement direction (53) for the field of vision (V) is determined on the basis of the partial outline (51) specified based on image data. In this way, even when measuring dimensions for a tool (20) with a larger diameter than the field of vision (V) of the imaging device (33), a partial outline (51) of a desired range, for example, is specified. An outline of a desired range for the tool (20) is extracted if a plurality of specified partial outlines (51) are combined.

  • Patent number: 9443310
    Abstract: A depth camera includes an illumination module and an image detector module. The illumination module outputs structured light that illuminates a capture area. The image detector module captures an image of the structured light as reflected from object(s) within the capture area. The illumination module includes a VCSEL array and optical element(s), such as projection optics, an MLA or DOE, or combinations thereof. Projection optics receive a light pattern emitted by the VCSEL array and project the light pattern. An optical element, downstream from the projection optics, can cause a total number of features included in the structured light to be greater than the number of features included in the light pattern projected by the projection optics. In an embodiment, a pitch of an MLA is offset relative to a pitch of the VCSEL array. Various structures can include alignment elements to aid manufacture of the illumination module.

  • Patent number: 9438893
    Abstract: A method for moving viewing positions of a stereoscopic image display system is described. Each cylindrical lens is tilted relative to vertical lines. A data stripe for left eye and a data stripe for right eye making up stereoscopic image data are alternately set to correspond to the cylindrical lenses. At a home position, a long axis of the cylindrical lens agrees with the center of each data stripe, thus concentrating light at a predetermined concentrating position. When setting stereoscopic image data at a different position of sub-pixels that is shifted vertically downward from the home position, the center of the data stripe is shifted relative to the long axis by 0.5 times the length of the sub-pixels horizontally to the left thus concentrating light at a concentrating position moved from the home position in the left-right direction.

  • Patent number: 9430046
    Abstract: An image capturing system for a vehicle captures an image of a target area based on a predefined gesture performed by an occupant of the vehicle. A gesture capture device determines a gesture position of a gesture, which is the predefined gesture, with respect to a reference point. An eye tracking device determines an eye position of the occupant based on a viewpoint of the occupant. A target area determination module determines a target vector extending from the eye position toward the gesture position and aligns an on-board camera with the target vector, such that the target vector passes through an image field-of-view of the on-board camera. The on-board camera captures an image of the target area which is within the image field-of-view, and the image is stored in a computer-readable medium.

  • Patent number: 9432665
    Abstract: In general, techniques are described for coding picture order count values identifying long-term reference pictures. A video decoding device comprising a processor may perform the techniques. The processor may be configured to determine a number of bits used to represent least significant bits of the picture order count value that identifies a long-term reference picture to be used when decoding at least a portion of a current picture and parse the determined number of bits from a bitstream representative of the encoded video data. The parsed bits represent the least significant bits of the picture order count value. The processor retrieves the long-term reference picture from a decoded picture buffer based on the least significant bits, and decodes at least the portion of the current picture using the retrieved long-term reference picture.
