  • Publication number: 20070242751
    Abstract: A decoding section generates decoded data from image data that is coded by using N×N orthogonal transform bases on image data of moving picture in pixel number blocks that are divided into N in horizontal and vertical directions. An inverse orthogonal transforming section performs inverse orthogonal transform processing on Nx×Ny pieces of decoded data generated by a decoded data generating section by using Nx×Ny inverse orthogonal transform bases corresponding to the low frequency side in association with downsizing scaling factors Nx/N, Ny/N in the horizontal and vertical directions to generate downsized image data. A position correction section performs position correction on a motion vector that represents a relative position of difference image data, if downsized image data is the difference image data corresponding to a difference from the downsized image data at a different time.

  • Publication number: 20050108920
    Abstract: This invention provides a vapor heat apparatus for treating fruits by killing insects such as, for example, a Mediterranean fruit fly, an orange small fruit fly, a Queensland fruit fly and a melon fruit fly or the like. The invention prevents thermal troubles experienced by fruits undergoing treatment by allowing each of the fruits stored in each of the fruit storing means to reach a predetermined fruit central temperature at substantially the same time. The vapor supplying means and the heat exchanger means are controlled in reference to a sensed signal of the fruit temperature sensing means.
