Abstract: A wide angle viewing apparatus for security applications is disclosed. The apparatus comprises a wide-angle lens and a diffusing screen. The wide-angle lens incorporates an image inverter and a means for eliminating stray light.

Abstract: The appearance of a color print viewed under UV illumination is predicted using a target comprising color patches each printed using a known coverage of printer colorant(s). In one case, the target is illuminated using a UV light source and an electronic image of the target is captured using a digital camera or the like. In another case, a spectrophotometer is used both with and without a UV cutoff filter to measure the target. The captured image data or the spectrophotometric measurements are used to derive a UV printer characterization model that relates any arbitrary combination of printer colorants to a predicted UV color appearance value. Metameric colorant mixture pairs for visible light and UV light viewing can be determined using the UV model together with a conventional visible light printer characterization model. A visual matching task is used to determine a correction factor for the UV printer characterization model.

Abstract: A method is provided for controlling an at least partly automatically implementable driving maneuver by which a motor vehicle can be moved from an actual position into a desired position. In the environment of the motor vehicle, a virtual target object is generated in a target position for the motor vehicle in the environment of the motor vehicle by projection using projection devices provided on the motor vehicle. As a function of operating actions of an operator of the motor vehicle, the target position is changed, whereby also the target object is displaced in the environment of the motor vehicle. And, by way of a selecting action of the operator, the changed target position is selected and utilized as the desired position of the driving maneuver.

Abstract: An end face of a narrow-diameter end portion is easily disposed at a correct position on an examination object without setting an examination site, thus enabling rapid and straightforward acquisition of an image of the examination site. The invention provides an alignment method for a guiding device which is attached to an end of an objective lens in such a manner as to be capable of positional adjustment in an optical axis direction and which is brought into contact with an examination target to make a focal position of the objective lens coincident with an examination site.

Abstract: A viewing device containing one or more display screens and adjustment means to allow the device to be adjusted to suit a user's interocular distance, wherein alignment means are provided to check the alignment of the device with the wearer's eyes.

Abstract: To provide an environment-compliant image display system and program, the system is provided with an environmental correction processing section for correcting an LUT in a 3D-LUT storage section, thus correcting colors, and a &ggr; correction section for correcting &ggr; values in a 1D-LUT storage section, thus correcting brightness, based on environmental information that has been measured by a colored-light sensor.
