Title: Encoding device
Inventor: MIYAMOTO MASAYUKI
IPC: H04N19/94
Filed: 1996-05-15
Abstract: PROBLEM TO BE SOLVED: To reduce the circuit scale and power consumption concerning an image compressor to use a vector quantization encoding method with which the scalar quantized code of a maximum inner product value with each code word in a code book and the index of a cord word to apply that maximum inner product value are encoded and outputted corresponding to the vector component of an input image inputted from an image sensor. SOLUTION: An inner product value calculation circuit 12 is composed of an analog circuit provided with a code component capacitor corresponding to respective code components, a differential amplifier and a feedback capacitor, and the inner product values with the input vector are parallelly operated by respective inner product value calculation parts R1 to RM corresponding to the code words. Thus, in the case of arithmetic after A/D conversion, arithmetic quantity or power consumption is remarkably increased by increase in the number of dimensions or gradations of the input vector but with analog arithmetic, such a problem can be canceled.

IPC: B41J3/28
Filed: 1989-05-15
Abstract: PURPOSE:To attain miniaturization and reduction of cost by biasing a photodetector in sequential direction with a switching circuit and in opposite direction at read. CONSTITUTION:A bias voltage is applied to a series circuit comprising a heat resistor and photodetection diodes 41-4n to apply forward bias to the photodetection diodes 41-4n with changeover circuits 111-11n and 121-12n. Thus, the resistance of the photodetection diodes 41-4n is negligibly small and a current sufficiently for recording flows to a heat resistor array 1 to attain the recording. A bias voltage is applied to the photodetection diodes 41-4n is reverse bias with the changeover circuits 111-11n and 121-12n at read. Since a charge current equivalent to the charge discharged with the photocurrent flows to only photodetection diodes 41-4n receiving light, the charge is extracted as a picture signal. Since the write head circuit and the read head circuit are integrated in this way, the small sized and inexpensive picture input and output head circuit is realized.

IPC: G02B27/10
Filed: 1977-10-12
Abstract: PURPOSE: To efficiently compose or separate plural beams by suing a Bragg's diffraction grating.  
     CONSTITUTION: A Bragg's diffraction grating 13 having a narrow angle selecting range is prepared. When a first beam 14 having a wavelength λ 1  is introduced into the grating 13 in the direction satisfying the Bragg's diffractive condition, it is diffracted as a beams 15 in an efficiency near 100%. When a second beam 16 having a wavelength λ 2  is introduced into the grating 14 in the same direction as that of the beam 15, most of it passes as it is and is turned into a transmitted beam 17. When the difference in Bragg's angle between the two beams 14 and 16 is higher than the angle selecting ranges β 1  and β 2  of the grating 13, the transmissivity of the second beam 16 becomes near 100% so that the two beams 14 and 16 are composed in high efficiency. If diffraction gratings 18 and 19 are used, beams 20 and 21 can also be composed. If the composed beam is irradiated in the opposite direction, the separation can be accomplished
