摘要： An image processing apparatus and an image processing method, applied to e.g. a TV conference system or a TV telephone system, in which an image to be transmitted or received is captured and reconstructed into a virtual view point image which may appear as if it is captured by a virtual camera. The correspondence between pixels may be taken with higher robustness and higher accuracy, while mismatch in such correspondence, otherwise caused due to disparity, may be reduced to as small a value as possible. To this end, the disparity between the images, obtained on imaging an object from different view points by at least two cameras 11a, 12a, are detected and, based on the detected disparity, each of the images is separated into plural image regions. The relation of correspondence is found of the separated each image region, in association with the object, from one pixel position on the same horizontal lines to the next. From the pixel positions and the associated luminance components, for which the relation of correspondence has been found, a virtual view point image, to be generated by a virtual camera, mounted imaginarily, is constructed.

摘要： A feed distributor used in fish ponds with feed supplied from below and thrown circumferentially comprises a feed-supplying mechanism, a feed-throwing mechanism and a feed-conveying mechanism by which feed supplied from said feed-supplying mechanism is delivered to said feed-throwing mechanism; the feed-supplying mechanism has a hopper which connects with a feed container above and a feed conveyor below. The feed-throwing mechanism has a launching disc with a sealed top, feed outlets in its circumference and a feed inlet below. The launching disc is disposed on a hollow shaft with an inner hole opposed to said feed inlet. The feed-throwing mechanism is disposed in pond and the feed supplying mechanism settles on a bank, feed is sucked into the feed-throwing disc and thrown circumferentially under negative pressure caused by rotation of the launching disc, and has a low crushing rate.
