Title: Orthogonal conversion encoding device for picture signal and decoder
Inventor: ITO KENJI
IPC: H04N19/60
Filed: 1988-02-29
Abstract: PURPOSE:To reduce the capacity of a storage device by encoding a conversion coefficient data of the 1st group without modifying the conversion coefficient data and encoding a difference data of the conversion coefficient data of other group from the conversion coefficient data of the 1st group. CONSTITUTION:The picture data is separated into plural group data by separating the picture data where picture signals are arranged adjacently and the result is subject to orthogonal conversion by orthogonal conversion circuits 24-1-24-n, only one orthogonal conversion coefficient data is encoded as it is by encoding circuits 26-1-26-n and the other conversion coefficient data is subject to difference calculation with a reference conversion coefficient data and then encoded. That is, since the picture data of plural groups are constituted and separated to include the picture data arranged adjacently, the correlation of data is high and the data after orthogonal conversion is an approximated value, then the encoding is attained efficiently by obtaining the difference to apply encoding. Thus, lots of picture data are stored in a storage device with a small storage capacity.

Title: Photographic printer
Inventor: SAIDA HIROBUMI
IPC: G03B27/72
Filed: 1995-03-03
Abstract: PURPOSE: To obtain a print which can be inconspicuously corrected even when the color and density are corrected. CONSTITUTION: By taking subject density on the abscissa axis and film density on the ordinate axis, the characteristic of negative film is expressed as a negative film characteristic curve 90, and by taking printing density at the abscissa axis and printing exposure on the ordinate axis, the characteristic of color paper is expressed as a color paper characteristic curve 92. A1 is a subject luminance range, D1 is the density change width of the negative film, and D2 is the density change width of the color paper. Generally speaking, in the case where an image is exposed from the negative film to the photosensitive material, the sensitivity area of photosensitive material is narrower than that of the negative film, so that the image is painted out in white or black on the color paper in the areas B2 and B3 .  Then, gradation correction is performed according to the density of the image of a transmissive original and a density difference formed on the color paper in every minute area for respective colors by a spatial optical modulation element after calculating the density in order to correct the paint-out of the image.

Filed: 1989-02-28
Abstract: PURPOSE:To lower the activity of the subject hemolytic compound and to enable safe intravenous injection of a large amount of the compound and long-term administration of the compound without causing side effect by condensing a highly unsaturated fatty acid with an acidic alpha-amino acid.

Filed: 1988-03-01
Abstract: PURPOSE:To output an adequate response sentence based on man's intention by collating the content of an interactive hysteresis storage device and specifying intention when the man has inputted at the time of interpreting inputs from the man. CONSTITUTION:A man's input sentence is analyzed in an input sentence analysis part 2, which converts the sentence into the internal expression of the device. An intention analysis part 3 collates the internal expression and hysteresis information being the content of the interactive hysteresis storage device 4, whereby intention when the man has inputted is specified. A response decision part 5 successively selects a response method corresponding to man's intention and decides the content of the response sentence. Finally, a natural language sentence corresponding to the response content is generated in an output sentence generation part 6. Thus, the adequate response sentence can be outputted by effectively using interactive hysteresis information even if inputs beyond prediction, which are the reasking from the man and the like, are executed.
