摘要： 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.

摘要： 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.
