  • Patent number: 7061534
    Abstract: A three-dimensional image capturing device has a center LED and peripheral LEDs which are arranged around the center LED. The center LED and peripheral LEDs irradiate distance measuring light beams to a measurement subject. The distance measurement light beams are reflected by a surface of the measurement subject, and the reflected light beams are received by an imaging device, so that distances from the imaging device to the measurement subject are sensed in accordance with the received light amount. The irradiation timings of the center LED and the peripheral LEDs are adjusted, in such a manner that, when the measurement subject is a flat plane parallel to the light receiving surface of the imaging device, the reflected light beams from all of the LEDs are simultaneously received by the imaging device.

  • Patent number: 6933962
    Abstract: An electronic endoscope comprises a housing and a flexible tube. A light-transmitting optic fiber and a light-receiving optic fiber are provided in the flexible tube. A light source and an imaging device are provided in the housing. The light source outputs a pulsed distance-measuring light beam, which is transmitted along the light-transmitting optic fiber, and irradiated to a subject. A reflected light beam generated by the subject due to the distance-measuring light beam is transmitted along the light-receiving optic fiber, to enter the imaging device, in which an electric charge corresponding to the subject image (i.e., an image signal of a three-dimensional image) is accumulated. A timing of the accumulating operation of the imaging device is delayed depending on the lengths of the fibers.

  • Patent number: 6907139
    Abstract: A three-dimensional image-capturing device comprises a first and second CCD and a first and second photographing lens. The texture or still image of a subject is captured by the first CCD through the first photographing lens. The distance image of which pixel data represents distance information from the device to each point on the surface of the subject is sensed by the second CCD through the second photographing lens. The three-dimensional coordinate data of each point on the surface of the subject is calculated from the distance information. The parallax between the first and second photographing lenses is compensated for with reference to the three-dimensional coordinate data of the subject.

  • Patent number: 6734450
    Abstract: A three-dimensional image capturing device comprises a light source for irradiating a distance measuring light beam to a subject. The light source has a plurality of light source rings, each of which is formed of a plurality of LEDs. The LEDs are annularly disposed along an outer periphery of a lens barrel. The ratio of the intensities of light beams irradiated by the first, second, third, fourth, and fifth light source rings is 1:2:4:8:16. The intensity of the distance measuring light beam irradiated by the light source rings is modulated by selecting the light source rings to be turned ON, so that the intensity of the distance measuring light beam changes in accordance with the time.

  • Patent number: 6710586
    Abstract: A band gap reference voltage circuit of the present invention includes a first band gap reference voltage formation portion for outputting a first reference voltage and a second band gap reference voltage formation portion for outputting a second reference voltage. The band gap reference voltage circuit then outputs a higher one of the first and second band gap reference voltage formation portions to output a constant reference voltage. Accordingly, even if one of the output voltages decreases caused by applying any stress for the first and second band gap reference voltage formation portions, the higher voltage is output as an output voltage of the band gap reference voltage circuit.

  • Patent number: 6687396
    Abstract: The image pick-up device picks up an image of the inspection target optical member whenever it rotates a predetermined angle. The image data which is output by the image pick-up device picking-up the image undergoes coordinate transformation from polar coordinate system to rectangular coordinate system and thereafter binarization process. The area of the defective candidate objects which are extracted from the image data in two color system obtained through the binarization process are normalized in accordance with the reference values prepared for each region in which said defective candidate objects formed within the image data. The points which are calculated as a result of this normalization, are added to the corresponding columns in the classification table. It is judged whether the inspection target optical member is satisfactory or not, in accordance with whether or not evaluation function calculated on the basis of the value in each column exceeds a predetermined reference value.
