Patent number: 9521401Abstract: Every frame regarding an input video signal is changed into a sequence of subframes. Subframe data is generated from the input video signal while first and second tables are alternately used. The first and second tables are designed so that a number of subframes assigned a pixel activated state increases each time a drive gradation related to the input video signal increases by 1. According to the first table, a subframe newly assigned the pixel activated state is one following the subframe or subframes which have already been assigned the pixel activated state when the drive gradation increases from an odd number to a next even number. According to the second table, a subframe newly assigned the pixel activated state is one preceding the pixel-activated-state subframe or subframes in that case. A display device is driven in response to the generated subframe data.Type: GrantFiled: August 14, 2013Date of Patent: December 13, 2016Assignee: JVC KENWOOD CorporationInventor: Akihiro Sato

Patent number: 9521399Abstract: Dynamic projection of at least first and second patterns contributes detectable disparity onto a scene that includes a target object. The scene is imaged with two-dimensional cameras whose acquired imagery includes disparity contributions whose presence enable a three-dimensional reconstruction depth map to be rapidly and accurately generated. In one embodiment coherent light is input to a first DOE within whose near range output is disposed a second DOE, whose far range output projects an image. Electronically varying effective optical distance between the two DOEs varies the pattern projected from the second DOE. A processor system and algorithms enable dynamic intelligent selection of projected patterns to more readily discern target object characteristics: shape, size, velocity. Patterns can implement spatio-temporal depth reconstruction, spatio-temporal depth reconstruction, and even single-camera spatio-temporal light coding reconstruction.Type: GrantFiled: April 25, 2016Date of Patent: December 13, 2016Assignee: AQUIFI, INC.Inventors: Aryan Hazeghi, Carlo Dal Mutto, Abbas Rafii, David Demirdjian

Patent number: 9518937Abstract: A method of inspecting articles of transparent/translucent material with a vision system comprises illuminating the articles with a light source having an angular spectrum that is adapted to the contrast selected for refractive items presented by the articles. An image sensor picks up the light that has passed through the articles to make images of the articles. During a stage of referencing the vision system, a reference standard is in the field of view of the image sensor, the standard including at least one standard item that refracts light in a known range of angles. An image of the standard is taken to measure at least the contrast in the image produced by at least one standard item. During at least one stage of qualifying the vision system, the standard is placed once more in front of the light source and in the field of view of the image sensor.Type: GrantFiled: January 25, 2013Date of Patent: December 13, 2016Assignee: MSC & SGCCInventors: Marc Leconte, Bernard Lopez

Patent number: 9451279Abstract: Provided is a method for decoding a moving picture. The method has the steps of generating a prediction block of a current block and generating a residual block of the current block. To generate the prediction block, a reference picture index and motion vector difference of the current block are obtained from a received bit stream, and spatial and temporal motion vector candidates are derived to construct a motion vector candidate list. A motion vector candidate corresponding to a motion vector index is determined as a motion vector predictor, and a motion vector of the current prediction unit is restored to generate a prediction block or the current block. Therefore, the motion vector encoded effectively using spatial and temporal motion vector candidates is correctly recovered and the complexity of a decoder is reduced.Type: GrantFiled: March 7, 2016Date of Patent: September 20, 2016Assignee: M & K HOLDINGS INCInventor: Soo Mi Oh

Patent number: 9445103Abstract: Systems, methods, and computer program products that can be used to determine a search range (SR) when performing motion estimation at, for example, a video encoder or decoder. Determining a motion vector for a current block during motion estimation may involve searching within a search window that may reside in a reference frame, or in a previously decoded block that spatially or temporally neighbors the current block. Such a search seeks a motion vector that minimizes a metric, such as a sum of absolute differences between corresponding blocks of reference frames. A motion vector that minimizes such a metric may be a good candidate for use in motion estimation. The search may become more efficient if a search range is determined such that the extent of the search is bounded. A search range may be determined at the block level or at the picture level.Type: GrantFiled: May 16, 2013Date of Patent: September 13, 2016Assignee: Intel CorporationInventors: Lidong Xu, Yi-Jen Chiu
