Patent number: 4656500Abstract: An adaptive type compression method for a color image in which each sequence of picture elements obtained by combination of sum-difference transformation with DPCM is compressed by being multiplied by an adaptive zonal filter. The sum-difference transformation is used to simplify transformation of the image into a spatial frequency zone. The zone filter characteristic is adaptively selected according to a predetermined transmission bit rate (compression rate). Further, this zonal filter characteristic is set so as to correspond with luminance and color difference signals. According to this method, image information to be recorded can be arbitrarily selected and distortion of the image at compressing and reproducing can be eliminated.Type: GrantFiled: April 27, 1984Date of Patent: April 7, 1987Assignee: Fuji Photo Film Co., Ltd.Inventor: Sumio Mori

Patent number: 4589256Abstract: A steam turbine plant includes a steam turbine with a shrink-fit type rotor and a gland seal steam supply apparatus that supplies gland seal steam into the gland portion of the steam turbine. The gland seal steam supply apparatus has an evaporator that uses main steam or turbine extraction steam as a heating medium. A steam supply apparatus supplies steam generated within the evaporator into the portions of the turbine which are in danger of developing stress corrosion cracks. The steam supply apparatus includes a pressure reducing apparatus for supplying steam at a reduced pressure into the portions which are in danger of developing stress corrosion cracks. A steam detecting apparatus detects the steam conditions in the rotor as a function of the turbine load and a control apparatus receives the detected signal from the steam detecting apparatus for the purpose of controlling either the pressure of steam generated within the evaporator or the operation of the pressure reducing apparatus.Type: GrantFiled: October 20, 1983Date of Patent: May 20, 1986Assignee: Tokyo Shibaura Denki Kabushiki KaishaInventors: Masashi Akiba, Ryuji Minagawa, Sumio Mori

Patent number: 4580162Abstract: An image compression system wherein the image is arranged in a block 1 of elements which are Hadamard transformed 2 and then quantized 3 into sequences. The DC component is prediction 4 into a DC error prediction term and all the sequences are then encoded 5 into a variable length code depending on the combination of the sequences. The variable length codes are written into a buffer memory 6 at an input bit rate and read therefrom at an output bit rate asynchronously with the writing. A counter 10 keeps track of the amount of unused space in the buffer memory and a quantization characteristic selector 9 uses this amount to determine the quantization level.Type: GrantFiled: November 18, 1983Date of Patent: April 1, 1986Assignee: Fuji Photo Film Co., Ltd.Inventor: Sumio Mori

Patent number: 4467346Abstract: An adaptative quantizer for use with color images separates each color component for separate quantization and breaks up the input image into a plurality of blocks. A quantization characteristic determining unit determines the characteristic to be used for a given block according to the distribution of quantization level values obtained when an estimation error in a preceding block is quantized according to a particular quantization characteristic. The characteristic may be changed when the distribution of quantization level values is smaller than or exceeds given threshold values.Type: GrantFiled: March 9, 1982Date of Patent: August 21, 1984Assignee: Fuji Photo Film Co., Ltd.Inventor: Sumio Mori

Patent number: 4454546Abstract: A band compression method for a shaded image in which a sample input picture element value and an estimation error obtained from an estimation value of the input picture element are converted into quantization values and coded. First codes are temporarily stored in at least one block of buffer memories according to a quantization step number. The estimation errors are converted into quantization values corresponding to the input picture element values. Each quantization value is converted into the first code when the estimation error is quantized corresponding to the estimation error and quantization value. The next picture element value is estimated in accordance with the quantization value.Type: GrantFiled: March 10, 1981Date of Patent: June 12, 1984Assignee: Fuji Photo Film Co., Ltd.Inventor: Sumio Mori
