Patent number: 10410327Abstract: This disclosure relates to techniques for synthesizing out of focus effects in digital images. Digital single-lens reflex (DSLR) cameras and other cameras having wide aperture lenses typically capture images with a shallow depth of field (SDOF). SDOF photography is often used in portrait photography, since it emphasizes the subject, while deemphasizing the background via blurring. Simulating this kind of blurring using a large depth of field (LDOF) camera may require a large amount of computational resources, i.e., in order to simulate the physical effects of using a wide aperture lens while constructing a synthetic SDOF image. However, cameras having smaller lens apertures, such as mobile phones, may not have the processing power to simulate the spreading of all background light sources in a reasonable amount of time. Thus, described herein are techniques to synthesize out-of-focus background blurring effects in a computationally-efficient manner for images captured by LDOF cameras.Type: GrantFiled: May 25, 2018Date of Patent: September 10, 2019Assignee: Apple Inc.Inventors: Richard D.

Patent number: 10290083Abstract: A method for deblurring a blurry image (400) includes the steps of: performing a first phase of deconvolution (202) with a first phase regularization spatial mask (300) to reconstruct the main edges and generate a first phase latent sharp image (404) having reconstructed main edges; and performing a second phase of deconvolution (204) with a second phase regularization spatial mask (304) to reconstruct the texture and generate a second phase latent sharp image (406). The second phase regularization spatial mask (304) can be different from the first phase regularization spatial mask (300).Type: GrantFiled: February 21, 2018Date of Patent: May 14, 2019Assignee: NIKON CORPORATIONInventor: Radka Tezaur

Patent number: 10262422Abstract: Exemplary embodiments of the invention as described herein generally provide for detecting the displacement of feature(s) within a visual image in cases where pattern matching fails due to the existence of aperture(s) caused for example by external condition(s) encountered in recording such an image over time. Technique(s) are disclosed for detecting the difference between displacement of a geometric feature of an object appearing within an image (e.g., an edge or smooth surface) that has an aperture and another feature (e.g., a corner) that does not since it is not symmetrically invariant.Type: GrantFiled: July 12, 2017Date of Patent: April 16, 2019Assignee: SAMSUNG ELECTRONICS CO., LTD.Inventors: Roee Sfaradi, Omry Sendik

Patent number: 10218968Abstract: A gaze contingent display technique for providing a human viewer with an enhanced three-dimensional experience not requiring stereoscopic viewing aids. Methods are shown which allow users to view plenoptic still images or plenoptic videos incorporating gaze-contingent refocusing operations in order to enhance spatial perception. Methods are also shown which allow the use of embedded markers in a plenoptic video feed signifying a change of scene incorporating initial depth plane settings for each such scene. Methods are also introduced which allow a novel mode of transitioning between different depth planes wherein the user's experience is optimized in such a way that these transitions trick the human eye into perceiving enhanced depth. This disclosure also introduces a system of a display device which comprises gaze-contingent refocusing capability in such a way that depth perception by the user is significantly enhanced compared to prior art.Type: GrantFiled: March 5, 2016Date of Patent: February 26, 2019Inventor: Maximilian Ralph Peter von und zu Liechtenstein

Patent number: 10165205Abstract: An image processing method is provided. The image sensor is controlled to output the merged image. The depth-of-field area is identified based on the merged image. The image sensor is controlled to output the color-block image. A first part of the color-block image within the depth-of-field area is converted into a first simulation image using a first interpolation algorithm. The second part of the color-block image outside the depth-of-field area is converted into a second simulation image using a second interpolation algorithm. The first simulation image and the second simulation image are merged to generate a simulation image corresponding to the color-block image.Type: GrantFiled: October 13, 2017Date of Patent: December 25, 2018Assignee: GUANGDONG OPPO MOBILE TELECOMMUNICATIONS CORP., LTD.Inventor: Cheng Tang
