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.

A vehicle zone monitoring apparatus that detects physical bodies present in the vicinity of the vehicle from infrared images photographed by infrared cameras provided on the vehicle includes an object extracting device that extracts object images that emit infrared radiation from the infrared image and an artificial structure identifying device that identifies whether or not an object is an artificial structure by comparing an image of a search zone in proximity to the object extracted by the object extraction device, to a reference image of a pre-registered artificial structure which serves as an element that defines an artificial structure, and that identifies the object as an artificial structure if: within the search zone in proximity to the object, a section having a high correlation with the reference image exists; and a distance between the vehicle and the object is equal to a distance between the vehicle and the section having the high correlation with said reference image.

摘要:
A zoom lens has, in order from the object side thereof, a positive first lens unit G1, a negative second lens unit G2 and a rear group having a positive refracting power and composed of at least one lens unit. The lens unit located closest to the object side in the rear group is a third lens unit G3. An aperture stop S is provided at a position closer to the image side than the second lens unit G2 and closer to the object side than the lens surface located closest to the image side in the third lens unit.

A media server device (40) can reproduce each of music compositions held in a built-in storage device (45). Moreover, the media server device (40), while being connected, can stream-distribute a digital content to a network player (51) so as to be reproduced in the network player (51). Reproduced digital content detection means (41) detects a music composition being reproduced. Stream-distribution means (42) stream-distributes data for reproducing the currently reproduced music composition as a notification music composition in the network player (51). Thus, it is possible to provide a media server device, a media server control method, and a program capable of enabling a particular partner to understand the reproduced digital content effectively and in the reproduction format.
