  • Patent number: 8767036
    Abstract: An imaging apparatus includes: an imaging device capturing a subject image through an optical system; an image signal processor having a function of combining multiple captured images into a single image, the images being captured during the period when the imaging apparatus is moved; and a control unit, wherein the image signal processor detects any effect of parallax or a moving subject based on the similarity among motion vectors between adjacent images, and the control unit issues a warning when the image signal processor detects any effect of the moving object or parallax to prompt image recapturing.
    Type: Grant

    Date of Patent: July 1, 2014
    Assignee: Sony Corporation
    Inventors: Noriyuki Yamashita, Toshifumi Fujita
  • Patent number: 8379078
    Abstract: An imaging apparatus includes: an imaging device that images an object image through an optical system; an image signal processing section having a function of combining a plurality of imaged images into a combined image piece, the imaged images being obtained while the imaging apparatus is swept; a position sensor capable of obtaining position information of the imaging apparatus; and a controller that processes information of the position sensor, wherein the controller sends a notification of an appropriate value of a sweeping angular velocity based on the detection information of the position sensor and outputs a warning signal when the sweeping angular velocity exceeds an appropriate range.

  • Patent number: 8310563
    Abstract: An imaging apparatus includes: an optical system having an optical axis changing element; an imaging device that images an object image through the optical system; an image signal processing section having a function of combining a plurality of imaged images into a combined image piece, the imaged images being obtained while the imaging apparatus is moved; and a controller that controls the optical axis changing element so that the optical axis is changed in a direction for negating the movement of the imaging apparatus, at least during periods when an electronic shutter of the imaging device is open, and that the optical axis returns to the vicinity of approximately the center of the movement of the imaging apparatus during periods when the electronic shutter is closed, wherein the controller performs the control of the optical axis with respect to a partial line in the central direction of the imaging device.

  • Patent number: 7015951
    Abstract: A picture generating apparatus according to this invention comprises: two image pick-up devices 3a, 3b or more adapted for picking up image of an object 2 to be imaged to generate picture data and respectively disposed at different positions; a correlation detecting section 5 for comparing, with each other, respective picture data generated by the respective image pick-up devices 3a, 3b on epipolar line determined by connecting correspondence points of line of sight connecting virtual position A and the object 2 to be imaged and line of sight connecting position of each of the image pick-up devices 3a, 3b and the object 2 to be imaged to detect correlation therebetween; and a distance picture generating section 5 for generating distance picture indicating distance between virtual position and the object to be imaged on the basis of correlation detected by the correlation detecting section 5.
