Patent number: 8497914Abstract: A night vision device and method for filtering a series of image frames that depict a moving subject, which thereby improves the signal-to-noise ratio of each image frame, is provided. A composite image is formed for each image frame by combining pixel values in a current image frame with pixel values in composite images corresponding to image frames acquired before the current image frame.

A bi-directional recursive filter is used to weight the contributions from the previous composite images and subsequent image frames with a decay constant. Motion of the imaging system is optionally compensated for by establishing a moving reference frame and shifting the image frames to account for this motion; thus, registering the image frames before filtering the current image frame.Type: GrantFiled: August 10, 2009Date of Patent: July 30, 2013Assignee: Wisconsin Alumni Research FoundationInventors: Charles Mistretta, Justin Mertes-Mistretta, Erick Oberstar, Ethan Brodsky

Patent number: 8451338Abstract: Object motion during camera exposure often leads to noticeable blurring artifacts. Proper elimination of this blur is challenging because the blur kernel is unknown, varies over the image as a function of object velocity, and destroys high frequencies. In the case of motions along a 1D direction (e.g. horizontal), applicants show that these challenges can be addressed using a camera that moves during the exposure. Through the analysis of motion blur as space-time integration, applicants show that a parabolic integration (corresponding to constant sensor acceleration) leads to motion blur that is not only invariant to object velocity, but preserves image frequency content nearly optimally. That is, static objects are degraded relative to their image from a static camera, but all moving objects within a given range of motions reconstruct well.Type: GrantFiled: March 28, 2008Date of Patent: May 28, 2013Assignee: Massachusetts Institute of TechnologyInventors: Anat Levin, Peter Sand, Taeg Sang Cho, Fredo Durand, William T.

Patent number: 8411155Abstract: An imaging apparatus capable of preventing photographing sensitivity from being increased more than necessary, reducing image quality degradation caused by camera shake or object shake and easily photographing images in good image quality. The imaging apparatus includes an imaging optical system that forms an optical image of a photographing object. An imaging sensor receives the optical image and converts the optical image to an electrical image signal. A detector determines, based on the image signal, whether the photographing object is a specific photographing object likely to move while a photograph is being captured that corresponds to information stored in a memory device provided to the imagining apparatus. A control section establishes an operational mode causing the imaging apparatus to continuously take a plurality of photographs of the photographing object when the photographing object is determined to be the specific photographing object that is likely to move.Type: GrantFiled: May 29, 2012Date of Patent: April 2, 2013Assignee: Panasonic CorporationInventor: Naoto Yumiki

Publication number: 20130070112Abstract: The present invention prevents unnecessary imaging operations when imaging is not required to be performed. In the present invention, a display panel includes a touch panel provided on the top surface thereof. An image sensor of an imaging section captures an image. A gyro sensor detects the movement of an imaging device. When the movement of the imaging device is detected by the gyro sensor, a control section prohibits an imaging operation by the imaging section in response to a touch operation performed on the touch panel. Conversely, when the movement of the imaging device is not detected by the gyro sensor, the control section performs an imaging operation by the imaging section in response to a touch operation on the touch panel.Type: ApplicationFiled: September 14, 2012Publication date: March 21, 2013Applicant: CASIO COMPUTER CO., LTD.Inventor: Kenji YOSHIZAWA

Patent number: 8400515Abstract: A motion vector detecting unit detects a motion vector of each block in a shot image, which is divided into a plurality of blocks, during an optical zooming operation. A linear function calculating unit calculates for each block a linear function that represents a straight line, the slope of which is the same as that of a line passing through the center of the shot image and a representative point and which passes through a vector detection point. A hand-movement motion vector calculating unit selects at least two blocks that have the calculated linear functions, the slope of which are different from each other, and obtains an intersection of graphs of the linear functions of the selected blocks so as to calculate a motion vector caused by hand movement. A hand-movement correcting unit corrects the hand movement in the shot image based on the calculated motion vector caused by the hand movement.Type: GrantFiled: February 3, 2010Date of Patent: March 19, 2013Assignee: JVC Kenwood CorporationInventor: Mamoru Chiku
