  • Patent number: 8134608
    Abstract: Disclosed is an imaging apparatus capable of enlarging a portion of an image captured by an imaging device of a fisheye camera and displaying the enlarged image on a display screen with little distortion. The imaging apparatus enlarges a section, which is a portion of an image captured by a fisheye camera, and displays the section on a display screen such that the enlargement ratios of points in the section are different from each other. An image processing method uses a change function that changes the enlargement ratio of a field angle depending on the place is used, and converts a portion of the captured image into a central projection image to generate a display image. The use of the change function makes it possible to generate a display image having high visibility.

    Abstract: An imaging part and sensors are provided on an eyeglasses-shaped frame, which connects to a body through a cable. When a cameraman wears the frame just like eyeglasses, a taking lens is directed in the same direction that the face of the cameraman faces, so that a subject to be captured can be in the same direction as a line of sight of the cameraman. The sensors generate detection signals upon detecting movement of muscles at the temples of the cameraman by detecting myoelectric impulses. The image recording apparatus is controlled in accordance with the detection signals, which represent an arrangement of the movement for control. For example, when the cameraman closes the right eye to move the muscles at the right temple, the subject is zoomed in, and when the cameraman closes both eyes, the captured image is recorded.
