摘要:
In a method for determining motion vectors for each of the plurality of image blocks (X, O) together constituting a television image, motion vectors are computed only for selected ones (X) of the image blocks, and motion vectors for the remaining ones (O) of the image blocks are interpolated at least in part from the computed motion vectors of the selected blocks.
摘要:
In a method of controlling a picture signal processing mode, first and second motion vectors are determined (ME, D.sub.T) for first and second fields, and a picture signal processing mode control signal is obtained by comparing (D.sub.T, -, COMP-R) the first and second motion vectors. The control signal may be transmitted along with, for example, a HDTV signal to give an indication to a TV receiver whether the signal originated from movie-film or from non-movie-film or be generated within the receiver.

An aerosol generating device (20) comprises a reservoir(1) for containing a liquid to be atomized and a nebulization chamber (3) for nebulizing a portion of the liquid received from the reservoir. The aerosol device further comprises liquid exchange means (7,8) for exchanging in use a further portion of the liquid received in the nebulization chamber with liquid from the reservoir to reduce a temperature increase of liquid in the nebulization chamber caused by heat produced by the piezo (4).

摘要:
In motion compensated interpolation of TV-pictures it is usual to divide the picture into a plurality of blocks, a motion vector being determined for each block. This division into blocks has the disadvantage, that sometimes block boundaries become visible (dirty window effect). The invention generates a continuous vector field from the blocked vector field with the aid of a median filter which calculates for each subblock (H1) from a number of subblocks (H1 . . . H4) into which each block (H) is divided, a motion vector based on the motion vectors of the original block (H) to which the subblock belongs, and of the original blocks (E, G) adjacent to the subblock (H1) concerned.
