Abstract: A configuration is adopted, which includes: a shallow-bottom hemispherical screen and a deep-bottom hemispherical screen, which are different in depth from each other. The deep-bottom hemispherical screen belongs to an entirety of a hemispherical screen composed of the shallow-bottom hemispherical screen and a peripheral edge portion of the hemispherical screen. In accordance with a type of an implemented ophthalmic test, a multifunctional ophthalmic test device drives the deep-bottom hemispherical screen or the shallow-bottom hemispherical screen so that either of the deep-bottom hemispherical screen and the shallow-bottom hemispherical screen can be located at a position onto which an ophthalmic test image is projected by a projector. In this state, the projector projects the ophthalmic test image onto either of the deep-bottom hemispherical screen and the shallow-bottom hemispherical screen.

Abstract: A light projection apparatus that projects light onto an arbitrary space and an object set in the space, comprising: projection light data generating means for generating projection light data for specifying the projection light; projection range setting means for setting a projection range onto which the light is projected and a non-projection range onto which the light is not projected in accordance with an operation of a user; projection data correcting means for correcting the projection light data so as to project the light onto the projection range set by the projection range setting means; projection light correction data drawing means for performing drawing processing for projection light correction data obtained by correcting the projection light data by the projection data correcting means; and light projecting means for projecting the light by using projection light drawing data generated by the projection light data drawing means.

Abstract: A lighting control device includes: an irradiation light generation unit that receives an irradiation light signal; coating correcting means for correcting the irradiation light signal so that an irradiation target object can be coated with irradiation light; and an irradiation light projection unit that projects the irradiation light by using the corrected irradiation light signal. The irradiation light includes coating light that coats the irradiation target object, and background light that becomes a background of the irradiation target object. The lighting control device includes: a first coating correction unit that corrects the irradiation light signal so as to cut an outline of the coating light in conformity with a shape of the irradiation target object; and a second coating correction unit that corrects the outline of the coating light in response to a positional relationship between an origin position of the irradiation target object and the irradiation light projection unit.

Abstract: Irradiation light LA and irradiation light LB, which are to be projected toward an irradiation target object from a plurality of irradiation light projection units, respectively, are corrected so as to be ached with outlines of the irradiation target object, which are viewed individually from the irradiation light projection units. In such a way, a surface of the irradiation target object is coated with irradiation light LA? and irradiation light LB?, which are narrower in range than the irradiation light LA and the irradiation light LA. In such a way, the irradiation target object having an arbitrary shape is coated with the plural pieces of irradiation light with high accuracy.

Abstract: An image display apparatus includes a projector 2 receiving an image signal and projecting image light and a screen 1 including a projection plane of arbitrary shape. The projector 2 and screen 1 are connected with link mechanisms 3a to 3c and link mechanisms 3b and 3d. The relative position and posture between the projector 2 and the screen 1 are automatically or manually changeable. The relative position and posture between the projector 2 and the screen 1 are measured, and correction parameters for correcting distortion of image light projected from the projector 2 onto the screen 1 are calculated from the previously set viewing position of the viewer and the shape of the projection plane of the projector 2. Based on the calculated correction parameters, the image signal inputted into the projector 2 is subjected to distortion correction processing. It is therefore possible to allow the viewer to see a clear image even if the position of the screen is changed.

Abstract: A fixing apparatus for controlling an oil transfer apparatus to maintain a releasing agent holding layer such that it is not always saturated with the releasing agent. This makes it a compact, cost-effective unit with a long service life and provides a uniform, stable oil coating that eliminates image noise problems. In order to use a constant and minimum necessary amount of releasing agent, a releasing agent supply nozzle is incorporated with multiple protrusive or retrusive droplet growth assisting members at or near multiple releasing agent discharge ports. The supply nozzle used for supplying the oil has multiple discharge holes having approximately equal opening cross-sectional areas and an equalizing member which equalizes the amount of oil discharged from each discharge hole. The outer diameter D1 of the oil supply roller, the outer diameter D2 of the metal core and the distance P of adjacent through-holes formed on the periphery of the metal core satisfy a relation, 0.6<D1.multidot.(D1-D2)/(D2.
