    Abstract: An anti-shake apparatus of a photographing apparatus comprises a movable unit, and a control apparatus. The movable unit has an imaging device, and can be moved in first and second directions. The control apparatus moves the movable unit to first, second, third, and fourth positions, and performs first, second, third, and fourth imaging operations, and a combination operation for obtaining an anti-shake image signal in which lag from hand-shake is corrected. In the first imaging operation, a first imaging position of a first photography frame in which lag corresponding to a first hand-shake quantity is corrected, is calculated, and a first image signal which is imaged at an overlapping area between an imaging field of the imaging device at the first position and the first photography frame, is obtained. In the combination operation, the anti-shake image signal is obtained by combining the first, second, third, and fourth image signals.

  • Patent number: 7239342
    Abstract: An object of the present invention is to generate an image which is prevented from being influenced by a movement while suppressing increase in noise components. When a movement is detected during exposure of an image capturing device to light, an image capturing apparatus stops the exposure of the image capturing device and amplifies an image signal obtained with the exposure, thereby compensating exposure shortage. Luminance information is extracted from a captured image, and color information is extracted from a live view image obtained at a timing different from a timing at which the captured image is obtained. By synthesizing the luminance information of the captured image and the color information of the live view image, noise components included in color information are reduced.

    Abstract: Positional shifts of subject images in plural areas of a light receiving surface are respectively detected in a blur detection apparatus for a camera for detecting blur based on chronological positional shifts of subject images on a light receiving surface. This allows blur of the main subject to be distinguished from that in the background in the image. The subject image position may be detected using an AF sensor. An acceleration sensor may be used for detecting blur in images with insufficient brightness or contrast. Blur detection by the acceleration sensor should account for a time interval between accelerations—one detected in one direction and the other in the opposite direction.
