  • Patent number: 8230101
    Abstract: Transfer control means (41) transfers part of held digital contents in an internal storage device (51) to a network storage device (57). List information presentation means (42) returns list information which makes the digital contents stored in the internal storage device (51) and the network storage device (57) as the held digital contents in response to a list presentation request for the held digital contents. Upon reception of a data transmission request, search means (43) searches where the held digital contents are currently stored. If the result of the search shows the network storage device (57), content data transmission processing means (44) allows the stream-delivery of the data from the network storage device (57) to a network player (56). There is provided a server device for media (40) capable of maintaining the convenience of playback in a network player, while properly dealing with the large total size of held digital contents.

  • Publication number: 20120092776
    Abstract: The invention relates to an electronic image pickup system whose depth dimension is extremely reduced, taking advantage of an optical system type that can overcome conditions imposed on the movement of a zooming movable lens group while high specifications and performance are kept. The electronic image pickup system comprises an optical path-bending zoom optical system comprising, in order from its object side, a 1-1st lens group G1-1 comprising a negative lens group and a reflecting optical element P for bending an optical path, a 1-2nd lens group G1-2 comprising one positive lens and a second lens group G2 having positive refracting power. For zooming from the wide-angle end to the telephoto end, the second lens group G2 moves only toward the object side. The electronic image pickup system also comprises an electronic image pickup device I located on the image side of the zoom optical system.

  • Publication number: 20120008214
    Abstract: An image pickup apparatus includes a zoom lens, and an image pickup element having an image pickup surface which receives an image which has been formed by the zoom lens, and converts to an electric signal. When an object having a uniform brightness is captured, at any state from the wide angle end to the telephoto end, the zoom lens satisfies conditional expression (A). The image pickup apparatus includes a shading correction parameter storage section which stores a shading correction parameter which differs at a front-surface side and a rear-surface side with respect to a center of an image, which is for correcting asymmetric shading at the front-surface side and the rear-surface side of the zoom lens, and a shading correction section which carries out correction operation of an image which has been picked up by the image pickup element, based on the shading correction parameter of (stored in) the shading correction parameter storage section.
