Abstract: A three-dimensional image capturing device comprises an imaging device, such as a CCD, having a plurality of photo-diodes, a vertical transfer unit and a substrate. An electric charge discharging signal and an electric charge transfer signal are periodically output, respectively. Due to the electric charge discharging signal, unwanted charge accumulated in the photo-diodes is discharged to the substrate. A distance measuring light beam is radiated on a measurement subject, and a reflected light beam from the measurement subject is sensed by the CCD, so that electric charge, corresponding to distance information from the device to the measurement subject, is accumulated in the photo-diodes. The electric charge is transferred to a vertical transfer unit due to the electric charge transfer signal.

Abstract: A three-dimensional image capturing device obtains distance information of a standard subject, to which the distance from the device to each point of a surface of the standard subject is known. Based on the distance information of the standard subject, correction data is sensed, which is an error of distance information sensed when using a measurement subject, to which the distance from the device to each point of a surface of the standard subject is unknown. A distance measurement is performed for the measurement subject, so that distance information is obtained. The distance information of the measurement subject is corrected using the correction data.

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.

Abstract: A three-dimensional image capturing device comprises an imaging device, such as a CCD, having a plurality of photo-diodes, a vertical transfer unit and a substrate. First and second electric charge discharging signals and an electric charge transfer signal are periodically output, respectively. Due to the first electric charge discharging signal, unwanted charge accumulated in the photo-diodes is discharged to the substrate. An output of the electric charge transfer signal is started before the end of the output of the first electric charge discharging signal, and ends after the start of the output of the second electric charge discharging signal. A reflected light beam, generated by a measurement subject due to a distance measuring light beam, is sensed by the photo-diodes. Due to the second electric charge discharging signal, the electric charge accumulation in the photo-diodes ends.

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.

The inner and outer cover layers combined have a thickness of 2.0-5.0 mm. This construction gives the golf ball an excellent scuff resistance when hit with an iron club, as well as an improved spin, feel, and flight performance upon a full shot with a driver.
