Publication number: 20140085492Abstract: Digital video stabilization is selectively turned off in circumstances where it could actually decrease the quality of a captured video. A video camera includes a device for directly detecting physical motion of the camera. Motion data from the motion detector are analyzed to see if video stabilization is appropriate. If the motion data indicate that the video camera is stable, for example, then video stabilization is not applied to the video, thus preventing the possibility of introducing “motion artifacts” into the captured video. In another example, motion as detected by the motion detector can be compared with motion as detected by the video-stabilization engine. If the two motions disagree significantly, then the video-stabilization engine is probably responding more to motion in the captured video rather than to motion of the camera itself, and video stabilization should probably not be applied to the video.Type: ApplicationFiled: September 24, 2012Publication date: March 27, 2014Applicant: MOTOROLA MOBILITY LLCInventors: Doina I.

A residue image is computed by performing spatial-temporal filter with a set of absolute image difference of image pairs from input images.

Patent number: 8537238Abstract: The present invention proposes a digital camera and a corresponding method for capturing and deblurring images which remove several disadvantages of the prior art. In particular, the hardware limitation as well as the motion restriction of the known conventional MIP approach have been overcome. According to the proposed approach, image frames are electronically moved by an electronic frame shifting means. This allows a frame shifting in any type or fashion, wherein no complicated hardware arrangement is needed, as this has been required according to the known conventional MIP approach. The proposed deblurring approach is not limited to any type of frame shifting pattern, and it is furthermore not limited to a one-dimensional motion of the frames, as it also works for the case of a two-dimensional frame motion. Similar as in the conventional Motion Invariant Photography approach, the frame shifting results in a motion-invariant blurred image which can be deconvoluted by a single deconvolution.Type: GrantFiled: April 4, 2011Date of Patent: September 17, 2013Assignee: Sony CorporationInventors: Muhammad Siddiqui, Haroon Farooq Qureshi, Klaus Zimmermann

Patent number: 8508601Abstract: An image sensing device includes two, left- and right-eye image sensors, and detects the rotation amount around the optical axis of the image sensing device, and the displacement amounts of the two image sensors in a plane perpendicular to the optical axis. The image sensing device performs control such that two pixels on the two image sensors having output the centers of the images to be cropped from the sensed images exist in the same position in the vertical direction in the plane perpendicular to the optical axis. The image sensing device also performs control such that the horizontal distance, in the plane perpendicular to the optical axis, between the two pixels of the two image sensors having output the centers of the images to be cropped from the sensed images is equal to the spacing between the two image sensors.Type: GrantFiled: May 31, 2011Date of Patent: August 13, 2013Assignee: Canon Kabushiki KaishaInventor: Suguru Kusanagi

Patent number: 8508606Abstract: An image deblurring system deblurs motion blurred images of a video stream captured from a moving object. An image deblurring method selects a blurred image from the video stream, selects blurred pixels from the blurred image, and calculates a movement offset for each of the blurred pixels according to coordinates of the blurred pixel in a frequency domain during the movement of the moving object. The method generates a point spread function according to the movement offset, and generates an image conversion formula according to the point spread function. The method converts each of the blurred pixels into a sharp pixel according to the image conversion formula, and generates a sharp image based on all of the sharp pixels.Type: GrantFiled: November 20, 2009Date of Patent: August 13, 2013Assignee: Hon Hai Precision Industry Co., Ltd.Inventor: Chien-Hung Liu

Patent number: 8508651Abstract: An image stabilizing apparatus includes a motion vector calculating part that calculates a motion vector between a plurality of images including a displacement caused by a motion of an image-pickup apparatus, a shake-correction parameter calculating part that receives the motion vector as input to calculate a shake correction amount, and an image transforming part that performs geometric transformation of the image in accordance with the shake correction amount. The shake-correction parameter calculating part performs variation amount calculation, variation amount correction and correction amount calculation based on the motion information between the plurality of images. The image stabilizing apparatus preserves a motion in video from an intended camera work and allows image stabilization for an unintended shake.Type: GrantFiled: March 22, 2011Date of Patent: August 13, 2013Assignee: Canon Kabushiki KaishaInventors: Hidetoshi Tsubaki, Mitsuhiro Saito, Takahiro Oshino

Patent number: 8497916Abstract: An image capture device includes: an optical system for producing a subject image; an imager, which receives the subject image and outputs a signal representing an image including the subject image; a sensor for detecting the shake of the device itself by the movement of the device; and an image processing section, which receives the signal representing the image and crops and outputs a part of the image and which changes the cropping range of the image, thereby reducing the shakiness of the subject image in the image that has been caused by the shake of the device itself. The image processing section determines whether the cropping range of the image needs to be changed based on the shake of the device itself that has been detected by the sensor or based on the motion of the subject image.Type: GrantFiled: June 2, 2011Date of Patent: July 30, 2013Assignee: Panasonic CorporationInventor: Motonori Ogura

Patent number: 8493495Abstract: The technology includes processor-implemented methods, computer program products, and electronic devices for media module control. Media module zoom specifications are requested. Media module zoom specifications comprising zoom range are received. The received zoom range is divided into n discrete steps. A zoom bar is presented comprises an indicator of increasing zoom direction, an indicator of decreasing zoom direction, and a slider bar is presented. The slider bar is disposed substantially between the indicators. The slider bar displays zoom level as one of the n discrete steps from a first step equal to no zoom level, and an nth step equal to full zoom level. User input regarding a zoom level is received. Zoom is performed on the displayed image. The relative zoom level is displayed in the zoom bar.Type: GrantFiled: December 16, 2010Date of Patent: July 23, 2013Assignee: Research In Motion LimitedInventors: Stephen Richard D'Souza, Robin Roy Glennie
