摘要:
A model eye that models the optical characteristics of a human eye and is endowed with a grayscale pattern on the ocular fundus model surface is stereographically photographed with a parallax via a stereo photographic optical system. Photographed images are processed to provide calibration data for correcting the shape distortions of the stereo photographic optical system. The calibration data is used to correct a distortion-affected shape data and parallax images obtained in stereographic photography of the actual ocular fundus of a subject's eye. The shape distortion-corrected parallax image is used for a three-dimensional measurement process and 3D display on a stereo monitor. This allows an accurate three-dimensional measurement to be carried out and an accurate fundus image to be produced. The examiner can accurately evaluate the stereo shape of the ocular fundus of the subject's eye.

An image forming apparatus includes a communication unit, a prohibition unit, an execution unit, and a control unit. The communication unit communicates with an external apparatus. The prohibition unit prohibits the communication unit from communicating with the external apparatus when a command for executing initialization with respect to the image forming apparatus is specified. The execution unit executes a process for accepting set information of the initialization when the prohibition unit prohibits the communication unit from communication with the external apparatus. The control unit executes a process for informing that the initialization should be executed when an elapsed time of a waiting state where input of the set information is not executed exceeds a given period.

A marine propulsion system includes a transmission mechanism arranged to transmit a driving force generated by an engine to propellers with a speed thereof changed to a low speed reduction ratio and a high speed reduction ratio; a control lever section operated by a user in controlling drive of the engine; and a control portion and an ECU controlling a shift between reduction ratios of the transmission mechanism based on operation of the control lever section by the user. The control portion and the ECU control a shift between reduction ratios of the transmission mechanism based on a transmission control map providing a reference for a shift between reduction ratios of the transmission mechanism taking into consideration an engine speed of the engine and a lever opening of the control lever section. This arrangement provides a marine propulsion system in which both acceleration performance and maximum speed can approach levels that a user desires.

A light beam reflected from an ocular fundus 1a is split into a pair of right and left light beams by a two-aperture stop 31 disposed in a position conjugate with an anterior ocular segment 1b of an eye 1 to be examined. The pair of right and left ocular fundus images having a parallax is formed as intermediate images from the split light beams at the position of a photographic mask 43. The optical path of the pair of ocular fundus images formed as intermediate images is split by a pair of optical path splitting lenses 51, 52 disposed in a position substantially conjugate with the two-aperture stop. One ocular fundus image is re-formed on half of an imaging plane 53a of an imaging element 53, and the other ocular fundus image is re-formed separately on the other half of the imaging plane. With such a structure, two ocular fundus images for three-dimensional viewing can be efficiently obtained without using a prism for splitting the optical path.

An outboard motor includes a prime mover, a marine propulsion unit having a propeller arranged to be driven by a rotational force of the prime mover to generate a thrust force, a shift position changing mechanism, a shift position changing mechanism actuator, and a control unit arranged to control the shift position changing mechanism actuator. When the shift position is changed to one of the first shift position and the second shift position from the neutral position, the control unit inhibits a change in the shift position to the other one of the first shift position and the second shift position until a predetermined time period elapses. The above arrangement improves the controllability of a boat propulsion system having an electronically controlled shift mechanism.

A propulsion system for a boat includes propellers arranged to be rotated by an engine, a transmission mechanism arranged to transmit driving force of the engine to the propellers such that a speed of the driving force of the engine is changed at least with a gear reduction ratio for low speed and high speed, and a control unit arranged to output a signal to control a gear shift in the transmission mechanism on the basis of an amount of lever opening, which is based on operation of a control lever section, and speed of the engine, and the control unit being arranged to detect cavitation generated in conjunction with rotation of the propellers on the basis of a gear shift control map. The control unit is arranged to control output of a signal to the transmission mechanism for changing a reduction gear to that for high speed when cavitation is detected.
摘要:
To observe interference stripes produced by tear fluid, a low magnification light source 10 is turned on to illuminate the outermost layer of a tear film on the cornea Ec of a subject's eye. Light reflected from the cornea Ec forms an image on a CCD 16, and an interference stripes pattern 18a created by the lipid film on the cornea is displayed on a monitor 18. To measure the amount of tear fluid, light-emitting elements 20a, 20b of a high-magnification light source are turned on to irradiate a tear fluid meniscus Em that has accumulated on the lower eyelid portion of the anterior ocular segment. Light reflected on the surface of the meniscus Em forms an image on the CCD 16, and images 18b, 18c of the light-emitting elements 20a, 20b are displayed on the monitor 18 as clear images separated by an interval D. The amount of tear fluid can be quantitatively measured by measuring the interval D. A single such structure allows interference stripes created by the tear film of the anterior ocular segment to be observed and the amount of tear fluid to be measured.
