Patent number: 8605995Abstract: An eigenprojection matrix (#14) is generated by a projection computation (#12) using a local relationship from a studying image group (#10) including a pair of a high quality image and a low quality image to create a projection core tensor (#16) defining a correspondence between the low quality image and an intermediate eigenspace and a correspondence between the high quality image and the intermediate eigenspace. A first sub-core tensor is created (#24) from the projection core tensor based on a first setting, and an inputted low quality image (#20) is projected (#30) based on the eigenprojection matrix and the first sub-core tensor to calculate a coefficient vector in the intermediate eigenspace. The coefficient vector is projected (#34) based on a second sub-core tensor (#26) created by a second setting from the projection core tensor and based on the eigenprojection matrix to obtain a high quality image (#36).Type: GrantFiled: July 26, 2010Date of Patent: December 10, 2013Assignee: FUJIFILM CorporationInventor: Hirokazu Kameyama -
Patent number: 8605994Abstract: Disparity in a stereoscopic image is converted, according to features of a configuration element of an image that influences depth perception of a stereoscopic image. A disparity detecting unit 110 detects disparity from a left image L and right image R of an input image, and generates a disparity map dM. A disparity correction unit 150 corrects the disparity in the disparity map dM and generates a corrected disparity map dM?. A correction feature setting unit 130 sets the correction features in the event of performing disparity correction in the disparity correction unit 150. The image synthesizing unit 160 synthesizes the left image L and right image R of the stereoscopic image based on the corrected disparity map dM? and outputs the stereoscopic image made up of a left image L? and right image R? as an output image. Thus, a stereoscopic image having disparity according to the set correction features is output.Type: GrantFiled: May 25, 2011Date of Patent: December 10, 2013Assignee: Sony CorporationInventors: Masami Ogata, Takafumi Morifuji, Suguru Ushiki

Patent number: 8538201Abstract: The invention relates to upscaling of images such as upscaling of video images from standard definition to high definition. An input image is upscaled to a resolution enhanced image (207) by weighting pixel values in the input image depending on a match metric combining two match metrics. A first image generator (103) generates a blurred version of the input image and a second image generator (103) generates an upscaled interpolated version. The first metric is generated by comparing pixel sets of the blurred image and the upscaled interpolated image. A second metric is generated by comparing pixel sets of the input image and already synthesized pixel values of the resolution enhanced image (207). For each location in a search area, a resolution enhancement processor (107) generates the combined match metric and uses this to weigh the pixel value of that location when generating the unknown pixel value of the resolution enhanced image (207).Type: GrantFiled: May 14, 2009Date of Patent: September 17, 2013Assignee: TP Vision Holding B.V.Inventor: Chris Damkat

Patent number: 8509482Abstract: A subject tracking apparatus which performs subject tracking based on the degree of correlation between a reference image and an input image is disclosed. The degree of correlation between each of a plurality of reference images based on images input at different times, and the input image is obtained.

Patent number: 8498447Abstract: The method operates by estimating the differential movement of the scene picked up by a vertically-oriented camera. Estimation includes periodically and continuously updating a multiresolution representation of the pyramid of images type modeling a given picked-up image of the scene at different, successively-decreasing resolutions. For each new picked-up image, an iterative algorithm of the optical flow type is applied to said representation. The method also provides responding to the data produced by the optical-flow algorithm to obtain at least one texturing parameter representative of the level of microcontrasts in the picked-up scene and obtaining an approximation of the speed, to which parameters a battery of predetermined criteria are subsequently applied. If the battery of criteria is satisfied, then the system switches from the optical-flow algorithm to an algorithm of the corner detector type.Type: GrantFiled: June 8, 2011Date of Patent: July 30, 2013Assignee: ParrotInventor: Thomas Derbanne

Patent number: 8494229Abstract: An eye tracker device (200) comprises a diffractive beam expander (207) to provide two substantially collimated illuminating light beams (B11, B12). The collimated light beams (B11, B12) provide two reflection spots (G1, G2) appearing in the image of the eye. The gaze direction (GZD) is calculated from the positions of the reflection spots (G1, G2) with respect to the pupil (P) of the eye (E1). The two illuminating beams (B11, B12) are provided by splitting an infrared laser beam (B4) into two in-coupled beams (B5, B6), which propagate in different directions in the substrate (7) of the beams expander. The in-coupled beams (B5, B6) are expanded and their light is subsequently coupled out of the substrate (7) by an out-coupling grating (230) to illuminate the eye (E1). The same substrate (7) may also be used to implement a virtual display device (100) for displaying virtual images to said eye (E1).Type: GrantFiled: February 14, 2008Date of Patent: July 23, 2013Assignee: Nokia CorporationInventors: Toni Järvenpää, Tapani Levola

Patent number: 8452057Abstract: A method controls a projection of a projector. The method predetermines hand gestures, and assigns an operation function of an input device to each of the predetermined hand gestures. When an electronic file is projected onto a screen, the projector receives an image of a speaker captured by an image-capturing device connected to the projector. The projector identifies whether a hand gesture of the speaker matches one of the predetermined hand gestures. If the hand gesture matches one of the hand gestures, the projector may execute a corresponding assigned operation function.Type: GrantFiled: October 6, 2010Date of Patent: May 28, 2013Assignee: Hon Hai Precision Industry Co., Ltd.Inventors: Chien-Lin Chen, Shao-Wen Wang
