Patent number: 8179471Abstract: A focusing device includes a distance information acquisition section acquiring information on a distance to a subject based on a plurality of image data acquired by taking images of the subject at a plurality of different viewpoint positions. A subject detection section detects a first area and a second area based on the distance information and threshold information for the distance range within which a subject of interest that obstructs a main subject in the subject is present. In the first area, the subject of interest is present in each of the plurality of image data. In the second area, the subject of interest is not present. A focusing estimation section estimates the focusing of the main subject based on the distance information on the second area in each of the plurality of image data.Type: GrantFiled: January 29, 2010Date of Patent: May 15, 2012Assignee: Olympus CorporationInventors: Toru Matsuzawa, Yoshinobu Tanaka, Eiji Igarashi

Patent number: 8098897Abstract: An image processing apparatus comprises a distance measurement section for measuring a distance from the section to a subject for each pixel on the basis of a plurality of images photographed at different visual point positions. A setting section sets a range of the distance in which an obstacle is present. An image formation section executes image processing of replacing a first image signal relating to an obstructed region included in the range of the distance with a second image signal different from the first image signal on the basis of an output from the distance measurement section.Type: GrantFiled: November 6, 2007Date of Patent: January 17, 2012Assignee: Olympus CorporationInventor: Toru Matsuzawa

Patent number: 7643742Abstract: An electronic camera detects a person's face image from an object image obtained by photographing an object, executes an enlarging process on the detected face image so as to obtain a face image whose face size is suitable, and displays the face image which is enlarged into the suitable size on a display device. When a plurality of people are present on the object image, the enlarged face images are switched by an image operating switch. As a result, the switched face image is displayed on the display device.Type: GrantFiled: November 1, 2006Date of Patent: January 5, 2010Assignee: Olympus CorporationInventors: Nobuyuki Watanabe, Fumiyuki Shiratani, Hiroshi Matsuzaki, Satoko Furuki, Akikazu Yachi, Hideki Nagata, Toru Matsuzawa

Publication number: 20080297648Abstract: A blurring parameter operating section calculates a blurring parameter corresponding to a distance from an optical system to a subject, based on two luminance information items which have different blurring degrees and are acquired by changing an arrangement setting of the optical system. A distance estimating section estimates distance information corresponding to the distance from the optical system to the subject, based on the blurring parameter. A focus detection section acquires luminance information after changing arrangement setting of the optical system based on the distance information, acquires luminance information items having different blurring degrees by further changing arrangement setting of the optical system, calculates an evaluation value indicating a degree of focus from each of the luminance information items having the different blurring degrees, and determines the focal position based on the evaluation value.Type: ApplicationFiled: May 14, 2008Publication date: December 4, 2008Inventors: Satoko Furuki, Akikazu Yachi, Toru Matsuzawa, Nobuyuki Watanabe

Publication number: 20080279422Abstract: An image processing apparatus includes a distance measurement section which measures a distance, on the basis of a plurality of images photographed by an imaging device at different visual point positions, from the imaging device to a subject for each pixel. A threshold setting section sets information indicative of a distance between an obstacle present between the imaging device and a main subject, and the imaging device. An image formation section compares the distance measured by the distance measurement section with the threshold information thereby to form an image from which an image of the obstacle is removed.Type: ApplicationFiled: May 8, 2008Publication date: November 13, 2008Applicant: OLYMPUS CORPORATIONInventor: Toru MATSUZAWA

Publication number: 20070147826Abstract: In a scene recognition photographing device of the present invention, a feature quantity of an acquired image acquired from an image pickup element is calculated from the acquired image. Plural types of reference feature information having a feature quantity serving as a reference at the time of determining a composition are stored as a database in an internal memory or a storage device. Moreover, a camera control unit retrieves reference feature information having a feature quantity similar to the feature quantity of the acquired image from among the reference feature information by comparing the calculated feature quantity and the reference feature information. Then, information relating to composition is displayed on a display device on the basis of a result of comparison between the acquired image and the retrieved reference feature information.Type: ApplicationFiled: November 27, 2006Publication date: June 28, 2007Applicant: OLYMPUS CORPORATIONInventors: Hiroshi Matsuzaki, Fumiyuki Shiratani, Nobuyuki Watanabe, Satoko Furuki, Akikazu Yachi, Hideki Nagata, Toru Matsuzawa

Publication number: 20070081082Abstract: An electronic camera of the present invention has a function for photographing combined images including plural continuously photographed images. A continuous photographing mode according to a moving subject is selected by a photographing mode selection unit. A continuous photographing interval, a maximum continuous photographing number, and a number of precaptured images to be obtained are set by a system controller according to the continuous photographing mode selected by the photographing mode selection unit. When a release button is depressed, continuous photographing is carried out under the photographing conditions of the continuous photographing mode selected by the mode selection unit.Type: ApplicationFiled: October 3, 2006Publication date: April 12, 2007Inventors: Nobuyuki Watanabe, Fumiyuki Shiratani, Hiroshi Matsuzaki, Satoko Furuki, Akikazu Yachi, Hideki Nagata, Toru Matsuzawa
