Patent number: 7711201Abstract: A method of and an apparatus for determining a depth map utilizing a movable lens and an image sensor are described herein. The depth information is acquired by moving the lens a short distance and acquiring multiple images with different blur quantities. An improved method of simulating gaussian blur and an approximation equation that relates a known gaussian blur quantity to a known pillbox quantity are used in conjunction with a non-linear blur difference equation. The blur quantity difference is able to be calculated and then used to determine the depth map. Many applications are possible using the method and system described herein, such as autofocusing, surveillance, robot/computer vision, autonomous vehicle navigation, multi-dimensional imaging and data compression.Type: GrantFiled: June 22, 2006Date of Patent: May 4, 2010Assignees: Sony Corporation, Sony Electronics Inc.Inventors: Earl Q.

Patent number: 7636107Abstract: An image-capturing apparatus, a method for processing signals, a recording medium, and a program that can improve the accuracy of an autofocus function with respect to a subject at the time of fill-light projection. A microcomputer monitors a fill-light controller and determines whether or not a fill-light projection flag is ON. If it is determined that the fill-light projection flag is ON, the microcomputer performs computation of the amount of control of image-blur correction to determine the amount of control of image-blur correction, and outputs the determined amount of control of image-blur correction to a detector. The detector determines the position of a detection frame for autofocus, changes the size or number of detection frames based on information on the zoom factor, and controls the position of the detection frame, and the size or number of detection frames.Type: GrantFiled: May 28, 2003Date of Patent: December 22, 2009Assignee: Sony CorporationInventors: Jinyo Kumaki, Satoshi Takemoto, Hidenori Kushida

Publication number: 20070189750Abstract: A method to simultaneously generate and capture a plurality of blurred images utilizing a camera lens and a plurality of imaging sensors is described. A signal passes through a lens and is then split into a plurality of signal paths of different lengths using a signal splitting device. Since the physical distances between the lens and the plurality of imaging sensors are different, with different signal path lengths, a plurality of uniquely blurred images are captured by the plurality of imaging sensors. Utilizing the plurality of blurred images, computations are performed and blur differences are calculated. A depth map is then determined from the blur differences. With the depth map, a number of applications are possible.Type: ApplicationFiled: February 16, 2006Publication date: August 16, 2007Inventors: Earl Wong, Makibi Nakamura, Hidenori Kushida, Soroj Triteyaprasert
