Patent number: 10506177Abstract: There are provided an image processing device, image processing method, image processing program, image capture device, and image display device that prevent increase of computational complexity in image enlargement while mitigating degradation in image quality. An image input unit inputs a planar image signal containing signal values of pixels arranged on a plane and depth information including depth values corresponding to the pixels. An interpolation unit calculates a signal value for an interpolation coordinate between pixels on the plane by interpolating between the signal values of adjacent pixels which are present within a predetermined range from the interpolation coordinate. A weight decision unit determines a weighting factor for use in the interpolation based on the depth value of a reference pixel that is closest to the interpolation coordinate and the depth value of an adjacent pixel.Type: GrantFiled: January 9, 2013Date of Patent: December 10, 2019Assignee: SHARP KABUSHIKI KAISHAInventors: Keisuke Omori, Kei Tokui, Nao Shibuhisa

Patent number: 10091489Abstract: An image capturing device includes at least two image sensors and an image processing unit that performs image processing on image information that is captured by image sensors and an image display unit that displays the image information on which the image processing is performed by the image processing unit. The image processing unit displays two base points on the image display unit in a same direction as a direction in which the two image sensors are arranged, calculates a disparity value between a first base point and a second base point that are the two base points with the two image sensors, calculates a length between the first base point and the second base point, and displays a result of calculation of the length between the first base point and the second base point on the image display unit.Type: GrantFiled: March 13, 2013Date of Patent: October 2, 2018Assignee: SHARP KABUSHIKI KAISHAInventors: Daisuke Murayama, Kenichi Iwauchi, Kei Tokui, Yasutaka Wakabayashi, Shinichi Arita, Nao Shibuhisa

Patent number: 9729844Abstract: In the related art, it was difficult to compare lengths of a plurality of objects which were present at different places. However, it is possible to easily compare lengths of photographed objects using an image capturing device which displays a length of an object which is calculated based on parallax information, by obtaining an image in which the object is photographed and the parallax information corresponding to the image as inputs, the device including an object extraction unit which extracts an image of an object using the parallax information from the photographed image; a comparison data maintaining unit which maintains the image of the object and the length of the object; an object comparison unit which compares the length of the object which is extracted using the object extraction unit to a length of comparison data which is extracted from the comparison data maintaining unit; and an image composition unit which combines a comparison result with the photographed image, and outputs the image.Type: GrantFiled: April 3, 2013Date of Patent: August 8, 2017Assignee: Sharp Kabushiki KaishaInventors: Nao Shibuhisa, Kei Tokui, Yasutaka Wakabayashi, Shinichi Arita, Daisuke Murayama

Publication number: 20150206354Abstract: The present invention provides a technology of generating a preferable self-photographing image when performing self-photographing in which an imaging direction of an imaging unit and a display direction of a display unit are aligned. An image processing apparatus includes a face information detection unit, a face direction calculation unit, an image parallel shift unit, a face model generation unit, and an image generation unit. In the face information detection unit, a face position information, face size information, and face component information of an object are detected. In the face direction calculation unit, face direction information of the object is calculated based on an arrangement of the face component information. In the image parallel shift unit, an image is shifted in parallel so that a face position of the object matches an image center.Type: ApplicationFiled: August 23, 2013Publication date: July 23, 2015Applicant: Sharp Kabushiki KaishaInventors: Nao Shibuhisa, Kei Tokui

Patent number: 8831338Abstract: Disclosed is an image processor generating a three-dimensional image easily three-dimensionally viewed by, and hardly causing fatigue of, an observer, and easily adjusting a three-dimensional effect of an arbitrary portion in the three-dimensional image. The disparity correction portion 101 corrects a disparity of the input disparity image within a predetermined range and outputs a disparity image storing the corrected disparity to the disparity conversion portion 103. The disparity conversion portion 103 converts the disparity of the disparity image such that a disparity corresponding to the image of the main object determined by the main object determination portion 102 reaches a predetermined value, and outputs the disparity image obtained after the conversion to an image generation portion 104. The image generation portion 104 generates an image for the left eye and an image for the right eye based on the input disparity image and the input captured image, and outputs the images to a display apparatus.Type: GrantFiled: May 24, 2011Date of Patent: September 9, 2014Assignee: Sharp Kabushiki KaishaInventors: Nao Shibuhisa, Kei Tokui
