IPC: G11B27/19
Filed: 1991-08-30
Abstract: PURPOSE:To improve the precision of a display by changing the pulse width of the regenerative signal of one control head among two control heads, and comparing the signal with the regenerative signal of the other control head. CONSTITUTION:When a video tape 1 is carried to an F direction, control signals are reproduced by control heads 6 and 9, and pulse waves are outputted from amplifiers 7 and 10 for control tracks. The pulse interval of the pulse width of the pulse wave is changed to 1/2 by a pulse width varying circuit 1, and a rectangular wave is prepared. The outputs of the amplifier 10 and the circuit 11 are added to an AND gate, and the heads 6 and 9 are arranged in an L interval so that the output of the gate 12 can be made constant by reducing the pulse width. The reverse of the tape 1 is operated in the same way. Thus, the proceeding and reverse of the display of a counter 8 can be coincident with the traveling direction of the tape 1.

Filed: 1987-09-02
Abstract: PURPOSE:To contrive the reduction of the error of information, by deciding with majority to a read output from the same address of memory cell arrays provided by three pieces or more and odd pieces. CONSTITUTION:As for read outputs Q0-Q2 from the same address of each memory cell arrays 2a-2c provided by connecting three pieces or more and odd pieces in parallel, the majority is taken by a majority circuit 4.

Title: Image coder and image decoder
Inventor: IWASAKI SHIRO
IPC: H04N19/00
Filed: 1995-08-29
Abstract: PROBLEM TO BE SOLVED: To attain information compression with higher efficiency by allowing an inverse quantization section to use an optional value from a minimum value to a medium in a quantization step for an inverse quantization value so as to suppress a quantization error. SOLUTION: An input image signal is given to a conversion section 101, in which signal conversion such as discrete cosine transformation or sub band division is applied and quantized by a quantization section 102. A coefficient signal quantized is divided into blocks by a block processing section 103 and subject to variable length coding by a variable length coding section 104 in the unit of blocks. The coded code word is given to a variable length decoding section 105, in which the code is variable-length-coded. Then inverse processing of block processing is applied by an inverse block processing section 106 and inverse-quantization is applied by an inverse quantization section 107. Then an inverse transformation section 108 applies inverse transformation to the discrete cosine transformation or the sub band division and the result is outputted as a decoded image signal.  Furthermore, an inverse quantization section 107 uses a value in the quantization step closer to 0 from a median for the inverse quantization value to reduce the quantization error.
