  • Apparatus and method for adjusting camera exposure
    Patent number: 10419684
    Abstract: As an apparatus for adjusting camera exposure, the apparatus includes: a virtual image generator generating a plurality of virtual images by changing brightness of an image photographed by a camera; a feature image generator generating a plurality of feature images respectively indicating features of the plurality of virtual images; and an exposure controller corresponding a feature value of the plurality of feature images to brightness, estimating reference brightness that corresponds to the maximum feature value, increasing camera exposure when the reference brightness is brighter than the photographed image, and decreasing the camera exposure when the reference brightness is darker than the photographed image.
    Type: Grant

  • Apparatus for controlling exposure of multi-view camera, system including the same, and method for controlling exposure of multi-view camera
    Patent number: 10230900
    Abstract: A system for controlling exposure of a multi-view camera is disclosed. The system includes a plurality of cameras having different views, a single image-based camera parameter calculator calculating single image-based camera parameters for each of the plurality of cameras; an image intensity ratio calculator calculating an image intensity ratio corresponding to an image intensity difference in an overlapped region between image data obtained from the plurality of cameras; and a multi-image-based camera parameter calculator calculating multi-image-based camera parameters for correcting intensity differences between images of the plurality of cameras on the basis of the single image-based camera parameters and the image intensity ratio.
