Title: Solid-state image pickup device
Inventor: NISHIYAMA HIROSHI
IPC: H04N5/335
Filed: 1986-07-02
Abstract: PURPOSE:To obtain the titled device with low cost by constituting it so that the optical image of an object is given from a first and a second solid-state image pickup elements in a manner that the picture elements are relatively shifted by a length of half picture element in the vertical scanning direction. CONSTITUTION:The first and the second solid-state image pickup elements SIDa and SIDb to which the same optical image of an object is given through an image pickup lens L and an optical member PSDa for halving optical signal, are so disposed that their light receiving planes are shifted by a distance lequal to the length of half picture element in the vertical scanning direction against the same optical image of an object. In such a way, by using two low- cost solid-state image pickup elements for sequential scanning, a video signal whose vertical resolution is virtually the same as that of a video signal to be obtained in a case using solid-state image pickup elements for sequential scanning whose number of scanning lines are double that of the said elements of this case, can be obtained.

Abstract: PURPOSE:To make unnecessary the synchronism of clock, by detecting the phase difference of the transmission and reception baud rate clock and shifting the tap coefficient of the transversal filter by one stage when the phase difference is in excess of +2pi and -2pi. CONSTITUTION:The output signal of the transversal filter 1 inputting the transmission symbol series is subtracted from the reception signal with the subtractor 2, and the output is sampled at the sampler 3 in the reception baud rate clock. Next, the tap coefficient of the filter 1 is corrected with the tap coefficient circuit 5 from the differential signal of the input and output signal of the discriminator 4. Further, the phase difference between the transmission baud rate clock R1 and the reception baud rate clock R2 is detected at the phase comparator 6, and when the phase difference is in excess of +2pi, -2pi, based on the polarity of the respective phase difference, the tap coefficient of the filter 1 is shifted right or left by one stage with the tap coefficient circuit. Accordingly, the operation is made with determined baud rate and no establishment of the synchronism of the transmission baud rate clock between MODEM's opposed is required.

Filed: 1999-06-03
Abstract: PROBLEM TO BE SOLVED: To improve parallelism and to suppress the reduction of code efficiency by including plural operation descriptions and a flag control description related to how to reflect a flag with the operated result in one machine instruction. SOLUTION: A machine instruction generating part 107 is composed of a dependent relation extracting part 120, a parallel intermediate code generating part 121 and a flag control code generating part 122.

IPC: H04N1/21
Filed: 1996-05-29
Abstract: PROBLEM TO BE SOLVED: To reduce the facsimile communication cost by converting the data in response to the stored capability of the opposite party and storing previously the converted data when the facsimile communication is started. SOLUTION: When a destination is inputted via a facsimile equipment 10, a conversion processing circuit 2 decides whether the destination is already registered in an opposite party capability storage part 3. If the destination is stored in the part 3, the capability that is used for the latest communication is read out of the part 3. The circuit 2 selects the capability and carries out the data conversion processing. In other words, the capability of the opposite party is stored in the part 3 when the communication is lately carried out with a facsimile equipment 20 of the receiver side. Then the data conversion processing is carried out, and the converted data are stored in a memory 4. Then the opposite party is called by a communication control circuit 5 and at the same time it's decided whether the capability of the opposite party is adaptive to the selected capability.  If the former capability is adaptive to the latter one, the data are transmitted as they are from the memory 4.
