The method generally includes the steps of (A) checking a motion condition of a current block in a current field in the video sequence for motion both (i) from a previous field in the video sequence to the current field and (ii) from the current field to a next field in the video sequence, (B) checking an artifact condition of the current block for a plurality of symmetric interlaced artifacts in both (i) a forward temporal direction and (ii) a backward temporal direction and (C) asserting a block motion indicator for the current block if all of (i) the motion condition is true and (ii) the artifact condition is true.Type: GrantFiled: January 30, 2006Date of Patent: September 20, 2011Assignee: LSI CorporationInventors: Yunwei Jia, Lowell L.

Patent number: 8022998Abstract: Exposed images from a CCD are each captured to Surfaces A, B and C in an SDRAM in a repeated sequence from A, B to C, and the latest image among the images thus captured is displayed. While an image on Surface B is being transferred, an image on Surface A is used as the image to be displayed. The next exposure is started, and images to be displayed are switched, at the same timing as the transfer is started. An image to be displayed on an LCD monitor is stopped from being updated when camera shake compensating device starts to be released from the mechanical holding. The next switching of images and the transfer of an exposed image from the CCD to the SDRAM are prohibited. When the release of the mechanical holding is completed, the next exposed image is transferred from the CCD to the SDARM. Updating is permitted for displaying the image which is transferred to the SDRAM on a display device.Type: GrantFiled: July 9, 2007Date of Patent: September 20, 2011Assignee: Ricoh Company, Ltd.Inventor: Atsushi Matsutani

Publication number: 20110211081Abstract: 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: ApplicationFiled: March 22, 2011Publication date: September 1, 2011Applicant: CANON KABUSHIKI KAISHAInventors: Hidetoshi Tsubaki, Mitsuhiro Saito, Takahiro Oshino

Patent number: 8009197Abstract: Systems and methods for providing a substantially de-blurred image of a scene from a motion blurred image of the scene are disclosed. An exemplary system includes a primary detector for sensing the motion blurred image and generating primary image information representing the blurred image, a secondary detector for sensing two or more secondary images of the scene and for generating secondary image information representing the two or more secondary images, and a processor for determining motion information from the secondary image information, estimating a point spread function for the motion blurred image from the motion information, and applying the estimated point spread function to the primary image information to generate information representing the substantially de-blurred image.Type: GrantFiled: December 22, 2008Date of Patent: August 30, 2011Assignee: The Trustees of Columbia University in the City of New YorkInventors: Moshe Ben-Ezra, Shree K. Nayar

Publication number: 20110199492Abstract: The present invention relates to a method and system for obtaining a point spread function for deblurring image data captured by an imaging device comprising a motion sensor. First, motion path values indicating the motion of the imaging device during the exposure time are acquired. The motion path values of the imaging device are then projected onto the sensor plane and for each sensor pixel the projected motion path values are integrated over time. Said integrated value represents for each sensor pixel an initial estimate of the point spread function. Optionally, the size of the point spread function can also be estimated based on the distance of the focused object and taken into account during the projecting step.Type: ApplicationFiled: February 3, 2011Publication date: August 18, 2011Applicant: Sony CorporationInventors: Daniel KAUKER, Muhammad Siddiqui, Klaus Zimmermann
