Title: Character feature extracting method
Inventor: SAKURAI TAKAHIRO
IPC: G06K9/46
Filed: 1993-02-26
Abstract: PURPOSE:To stably extract the feature of a character without performing filtering processing to eliminate a noise or a binarization processing on a character image of multi-gradation by providing an extension coefficient calculation step and a statistical processing step to calculate a representative value from a pair of extension coefficients and to output the representative value as a numeral sequence. CONSTITUTION:An original image is acquired first in step 10, and a rotary image in which an acquired original image is rotated by 45 deg. is generated in step 11. Each of the original image and the rotary usage is developed by a two-dimensional wavelet base, respectively in step 12, then, the extension coefficient is calculated. Thence. the representative value of the extension coefficient on which a similar feature is affected is calculated by statistical processing in step 13, and the numeral sequence representing the feature can be acquired in step 14. In such a case, the mean of the absolute values of the extension coefficients for a base in which lengthy line segments can be superimposed mutually by performing parallel displacement, and a base in which they can be superimposed by performing magnification/reduction in a direction intersecting orthogonally to the line segment is set as the feature of the character.

Filed: 1986-02-24
Abstract: PURPOSE:To constitute a hardware without using a high speed element by performing the first half or a predictive coding processing in parallel with a prediction system selecting processing and thereafter performing the second half of the predictive coding processing until a local decoding signal is obtained from a selection signal and a selected signal. CONSTITUTION:The coding processing in an adaptive predictive coder is divided into three of the first half part of the predictive encoding processing consisting of a prediction processing Bi', a quantizing processing Ci' and a local decoding processing Di', the second half part of the predictive coding processing consisting of a selection processing Ai' and the prediction system selecting processing. As for the sequence of these processing and the timing for generating the respective signals, in the (i+1)th sample, the time t8' requiring the selection signal S(i+1) is the later stage than the start time t5' of the (i+1)th sample time.

Title: Moving picture decoder
Inventor: WAKAMORI MASAHIRO
IPC: H04N19/00
Filed: 1989-02-17
Abstract: PURPOSE:To prevent deterioration in picture quality of a video image by discriminating quantizing noise of a frame depending on a decoded signal of a moving picture signal so as not to output a video image of a frame having much quantized noise. CONSTITUTION:A quantization step size decoded by a decoder 1 is stored in a memory 10, and when a frame memory switching judging device 11 judges a quantized step size stored in the memory 10 to be rough, the judging device 11 outputs a frame switching inhibit signal to a frame memory controller 12. The frame memory controller 12 depending on the frame switching inhibit signal controls video display frame memories 7, 8 and a selector 9 so as to read 2 frames of a reproduced picture element of the preceding frame consecutively. Thus, the frame whose quantized step size is rough is in the so-called frame shot resulting that the quality of the displayed video image is not deteriorated.

Title: Transmitting system of digital signal
Inventor: TAN YOUICHI
IPC: H04J3/00
Filed: 1981-03-19
Abstract: PURPOSE: To minimize the malfunction of a system which is due to a code error in the transmission mode, by monopolizing the divided minor frames on the time axis in a major frame on the time axis through a station that performs the transmission of signal as a unit and then carrying out the transmission of the signal is multiplexed in a time shared way.  
     CONSTITUTION: In case plural stations start at one time the transmission of the packet signal, a collision detecting circuit 61 recognizes the collision of packets and then discontinues the transmission of the packet signal of the own station. Then the packet signal of the own station is transmitted again after the random waiting time produced by a random number generator elapses. In case the transmission of the packet signal is started by stations R 1 ∼R 4  to a station S that already started the transmission of the random signal, the stations R 1 ∼R 4  decide the transmission timing of each transmitting packet so that the reception is started at a reference station C when one guard time elapsed after the station C completed the reception of the packet transmitted from the station S. In such way, the signal is transmitted so that the packets are arranged equidistantly at the receiving point of the station C.

IPC: H03G3/20
Filed: 1982-03-11
Abstract: PURPOSE:To prevent the malfunction of an automatic gain control circuit due to a signal hit, by providing a switched capacitor circuit at the output side of an error detecting part of signal level in order to hold the control signal. CONSTITUTION:A full wave rectifier FWR and an operational amplifier OP2 perform the detection of an error between signal levels as well as the multiplication of the signal levels by obtaining the difference between the mean level of the output V0 of a lead 14 and the reference voltage REF and then multiplexing the loop gain to said difference. An integrator 111 has a switch to change over a capacitor CS by a clock fS and charges the control voltage on a lead 102 to the capacitor CS. The clock fS is set at O when the signal voltage V1 has a hit and stops the changeover of a switch SW. Therefore a capacitor C holds the voltae obtained immediately after the changeover of the SW, and the voltage of the amplification factor control signal VG is held as it is. The gain of a variable gain amplifier VGA is also kept as it is.
