Patent number: 9749533Abstract: This image pickup apparatus performs feedback control so that a position of a shake correcting lens converges to a target position. A LPF and a subtracting unit divide a shake signal into low-frequency and high-frequency components. An adding unit combines each output of a high-frequency LPF and a low-frequency LPF and output the target position. A pan/tilt determination unit determines a panning speed from the shake signal. If the panning is fast, the target positions of the low-frequency and the high-frequency are controlled to converge to 0, and calculation for the target position of the high-frequency starts before that of the low-frequency at the end determination. If the panning is slow, only the target position of the low-frequency is controlled to converge to 0. The pan/tilt determination unit changes a determination condition for the detection depending on whether it is at the handheld photographing or the static state.Type: GrantFiled: December 2, 2014Date of Patent: August 29, 2017Assignee: Canon Kabushiki KaishaInventor: Kenji Takeuchi

Patent number: 9743001Abstract: A method operable within an image capture device for stabilizing a sequence of images captured by the image capture device is disclosed. The method comprises, using lens based sensors indicating image capture device movement during image acquisition, performing optical image stabilization (OIS) during acquisition of each image of the sequence of images to provide a sequence of OIS corrected images. Frame-to-frame movement of the device for each frame during which each OIS corrected image is captured is determined using inertial measurement sensors. At least an estimate of OIS control performed during acquisition of an image is obtained. The estimate is removed from the frame-to-frame movement determined for the frame during which the OIS corrected image was captured to provide a residual measurement of movement for the frame. Electronic image stabilization (EIS) of each OIS corrected image based on the residual measurement is performed to provide a stabilized sequence of images.Type: GrantFiled: February 19, 2016Date of Patent: August 22, 2017Assignee: FotoNation LimitedInventor: Piotr Stec

Patent number: 9247138Abstract: An optical device that is capable of reducing eccentric aberration while reducing image blur. A first shake correction unit corrects image blur optically based on a shake amount that is detected by a shake detection unit. A second shake correction unit corrects image blur optically based on a shake amount that is detected by the shake detection unit. The second shake correction unit has a different image blur correction effect from the first shake correction unit. The optical device has a mode in which shake correction is performed using the first shake correction unit without using the second shake correction unit.Type: GrantFiled: May 21, 2014Date of Patent: January 26, 2016Assignee: Canon Kabushiki KaishaInventor: Yu Narita

Patent number: 9131155Abstract: A system, method, and computer program product for digital stabilization of video data from cameras producing multiple simultaneous views, typically from rolling shutter type sensors, and without requiring a motion sensor. A first embodiment performs an estimation of the global transformation on a single view and uses this transformation for correcting other views. A second embodiment selects a distance at which a maximal number of scene points is located and considers only the motion vectors from these image areas for the global transformation. The global transformation estimate is improved by averaging images from several views and reducing stabilization when image conditions may cause incorrect stabilization. Intentional motion is identified confidently in multiple views. Local object distortion may be corrected using depth information. A third embodiment analyzes the depth of the scene and uses the depth information to perform stabilization for each of multiple depth layers separately.Type: GrantFiled: December 19, 2011Date of Patent: September 8, 2015Assignee: QUALCOMM Technologies, Inc.Inventors: Yuri Dolgin, Eran Pinhasov
