IPC: H04N5/232
Filed: 1993-12-27
Abstract: PURPOSE:To attain high speed focusing by recognizing a set of blocks in which total sum of DCT coefficients obtained by a DCT arithmetic operation means exceeds a threshold level as an object and executing AF control to trace an optional object such as a mobile body. CONSTITUTION:Block data comprising 8X8 picture elements longitudinally and laterally as to all patterns are fed from a buffer memory 6 to a lens AF arithmetic operation control circuit 30. The circuit 30 applies DCT arithmetic operation to the received block data to obtain a transformation coefficient. In the case of tracing a mobile body, video images of one pattern are subjected to DCT arithmetic operation and a tracing area is locked to an object desired to be traced. Then a total sum of absolute values of all AC transformation coefficients of DCT coefficients is obtained for each block and a portion where the total sum is a predetermined threshold level or over is used for an object desired to be traced. Furthermore, only consecutive areas are extracted for noise suppression, resulting that a major object is extracted. Then data for tracing a mobile body or hand-shake correction are obtained to make the focusing highly accurate.

Title: Motion discrimination device
Inventor: FUKUSHIMA MICHIHIRO
IPC: H04N19/50
Filed: 1996-12-11
Abstract: PROBLEM TO BE SOLVED: To reduce the circuit scale and to improve motion detection accuracy. SOLUTION: A motion detection circuit 21 detects a motion in the unit of macro blocks based on information of a motion vector and information of an image structure from a variable length decoding(VLD) circuit. As to an area whose motion is discriminated to be zero by the motion detection circuit 21, a mixing ratio generating circuit 22 discriminates whether the area is a still area or a moving area, based on a level of a prediction error to obtain mixing ratios (1-m), m. Multipliers 14, 15 and an adder 16 mix an in-field interpolation signal and an inter-field interpolation signal based on the mixing ratio. The inter-field interpolation signal is used only in the case that no motion is discriminated by the motion vector and the prediction error and in the case of a progressive image. No frame memory is used for motion discrimination and the circuit scale is reduced.  Moreover, a prediction error is used for motion discrimination and the detection accuracy is improved.

Filed: 1996-12-11
Abstract: PROBLEM TO BE SOLVED: To detect a distance with high accuracy by detecting a distance of an object on the basis of corrective propagation time of a feflected pulse of the object calculated by a specific procedure. SOLUTION: A reflecting surface 40 of a reference reflecting means is provided on one side of an irradiating window 3 of an inside surface of a case 39 of a laser sensor. Reflecting time of a laser pulse reflected by the reflecting surface 40 with every single scan, substantially becomes time on the basis of circuit operation since a reflecting optical path is very short, and this reflecting time is different in respective laser sensors, and is also different in response to an outside air temperature. That is, the reflecting time of the laser pulse obtained by the reflecting surface 40 with every scanning time, is characteristic of its laser sensor, and becomes real-time. The reflecting time of the reflecting surface 40 is subtracted from on street reflecting time with every scan by a main body apparatus, and substantial on-street reflecting time is calculated.  In this way, accurate distance data is obtained on the basis of the substantial on-street reflecting time from which inflience of circuits of the respective laser sensors is reliably removed, and a shape of a vehicle can be also discriminated.

Abstract: PURPOSE:To improve an extinction ratio characteristic and to shorten the optical path length over the entire part so as to decrease the misalignment of an optical axis by using one polarization beam spliitter which spectrally splits the linearly polarized light from a light source and multiplexes the light modulated in frequency. CONSTITUTION:The linearly polarized light from an LD or the like which is the light source is split by the polarization beam splitter 4 into a P wave and S wave which are the linearly polarized light intersecting orthogonally with each other. The respective light rays are introduced to AOMs 6A, 6B varying in driving frequency where the light rays are Bragg diffracted and receive a frequency shift. These linearly polarized light rays are made incident on a lambda/4 plate 5 inclined in its intrinsic axis to the incident polarization plane by +45 deg. or -45 deg. and are converted circularly polarized light rays. These light rays are reflected by a mirror 7 and are again passed through the lambda/4 plate 5. The light rays rotated by 90 deg. in the plane of polarization from the initial state are thus obtd. Just one piece of such polarization beam splitter 4 is used. Then, the extinction ratio characteristic is improved and the optical path is shortened. The influence of the optical axis misalignment by disturbances, such as vibration and air current, is decreased.

IPC: B60L9/18
Filed: 1997-12-02
Abstract: PROBLEM TO BE SOLVED: To provide an idling re-adhesion controller for electric rolling stock, which can attain optimum controlling condition as idling re-adhesion control. SOLUTION: Acceleration variations Δα1 to Δα4 and velocity errors ΔV1 to ΔV4 are calculated from respective shaft speeds fm1 to fm4 with an idling detection part 9. Factors g1 to g4 which indicate adhesive conditions based on the acceleration variations Δα1 to Δα4 and the velocity errors ΔV1 to ΔV4 are estimated by adhesive condition estimation parts 10 to 13. Based on the factors g1 to g4 and a current command value Ir at non-idling, a current command level Ia is determined by a current command level setting part 14.  Since the current command level Ia is inputted into a primary lag system 16 so as to obtain an output current command value Ip during idling re-adhesion control, the retention time of the output current command value Ip during the idling re-adhesion control condition becomes zero, so that the variation range of the output current command value Ip also becomes small.

Title: Semiconductor light emitting device and light modulation
Inventor: KOTAKI YUJI
IPC: H01S5/0625
Filed: 1987-12-29
Abstract: PURPOSE:To control oscillation frequency by light, by making highly intensity- modulated light signals come in the phase modulating region of a semiconductor laser having a reflecting mirror of a diffraction grating an changing the refractive index of a guide layer in the above region, thereby varying the light wavelength. CONSTITUTION:When the frequency of a light emitting wavelength 1.55mum is modulated, for example, by 1.3mum signal light incidence, an n-type guide layer 3 absorbs inputted lights. In such a case, for example, as a forbidden band width lambdag is 1.4mum and a p-type clad layer 5 is an optical confinement layer and further, is penetrated by the inputted lights, for example, InP has lambdag of 0.9mum. The selection reference of the forbidden band width is that the wavelength of the guide layer which is to absorb inputted lights is longer than each wavelength of the inputted lights and the wavelength of a clad layer which locates at the upper side of the guide layer and is to transmit inputted lights is shorter than that of the inputted lights. In such a case, fundamental light emitting wavelength is adjusted by voltages applied to the phase adjusting region and the diffraction grating region of a semiconductor laser. If AM lights of 1.3mum come into the phase adjusting region through a transparent electrode, the guide layer absorbs the lights and then, refractive index varies according to their light intensity.

Abstract: PURPOSE:To enable the control of an air intake flowrate with a single air valve during each drive mode of a vehicle by making the selective open/close control of the air valve fitted at an air intake passage using a plurality of control means. CONSTITUTION:When a throttle valve 10 fitted at the downstream side of a main throttle part 3 in an air intake passage 2 is opened, there increases negative pressure at the downstream side of an air valve 4 provided at the upstream side of the throttle valve 10.
