Abstract: A method to display images using four or more different primaries having different spectral distributions wherein, in the LMS color space, at least two of these primaries have the same L coordinates and the same M coordinates; thank to the invention, different metamers, when being legally displayed, will be not only perceptually indistinguishable to a viewer with normal color vision but also indistinguishable by most of the viewers with non-normal color vision.

Abstract: A light-filtering module includes a light-source module, a dichroic mirror and a first image unit. The light-source module outputs a light beam. The dichroic mirror divides the light beam into a first colored light and a dual colored light. The first image unit provides the first colored light with image information. The light-filtering module includes a light-filtering unit and a driving unit. The light-filtering unit is located between the dichroic mirror and the first image unit is located at a light path of the first colored light. The driving unit includes a coupling element coupled to the light-filtering unit and a driving element utilized to drive the coupling element. The driving element drives the light-filtering unit, switching between a first status and a second status by the coupling element. A wide-wavelength spectrum and a narrow-wavelength spectrum are provided when the light-filtering unit is in the first and second statuses, respectively.

Abstract: A color filter (1) for illumination purposes, such as, for example, for stage illumination is proposed, which comprises a full-surface antireflection layer (3) and an additional, multilayered structured interference filter layer (4) arranged on it.

Abstract: The invention describes a method for control of a device (1a, 1b, 1c). The method comprises visually presenting a number of user options for the device to be controlled (1a, 1b, 1c), aiming a pointing device (2) comprising a camera (3) at the visual presentation (4a, 4b, 4c, 4d, 4e) of the user options to choose a desired option, generating an image (5) of a target area (6) aimed at by the pointing device (2) and comparing the target area image (5) with a pre-defined template of the visual presentation (4a, 4b, 4c, 4d, 4e) to determine the chosen option.

Abstract: A color adjusting method is applied to a projector. The projector has a light emitting element and a color wheel. The light emitting element supplies light, and makes the light pass through the color wheel so as to generate a plurality of different color lights. These different color lights are used to form a color image. The color adjusting method includes the steps of providing a plurality of driving waveforms which is dynamically switched for driving the light emitting element; defining a major color light of the color image, which is selected from the different color lights; and switching to one of these driving waveforms when the major color light is generated by the light passing through the color wheel. Thus, the light energy of the major color light is enhanced by means of driving the light emitting element through the switched driving waveform.

Abstract: A method and system for color correcting and completing answerprints in preparation for making final copies of motion pictures for distribution. A light system is provided in which colors of the light projected through a film toward a viewing screen can be individually and incrementally adjusted as desired for use by a color “Timer” who is an individual that selects color corrections on a scene-by-scene basis until a suitable look is achieved. The Timer does this in real time while watching the film scene projected on the screen. The color adjustments are stored and subsequently used to control a motion picture film printer in printing a next version of scenes of the film.

Abstract: A liquid crystal display apparatus which includes: a light-addressed liquid crystal light valve including a photoconductive layer and a liquid crystal layer between a pair of light transmitting substrates, each of the light transmitting substrates having an electrode for applying a voltage across the photoconductive layer and the liquid crystal layer; a writing unit for writing an image of a display medium in the light-addressed liquid crystal light valve with writing light from the display medium through a writing lens; a projecting unit for projecting the image written in the light-addressed liquid crystal light valve by irradiating reading light from a projection light source to the light-addressed liquid crystal light valve; and a controlling unit for controlling at least one of operational characteristics of the light-addressed liquid crystal light valve and a luminance of the writing light in accordance with a luminance of the display medium, is disclosed.

Abstract: A system is disclosed in which individual frames are colorized by the addition of manually generated color. Color information is blurred, for example, by passing through a low resolution digital encoder for use in frames adjacent to the one being individually colorized. Interpolative techniques are used to reduce the number of frames which have to be individually colorized.

Abstract: Right and left projected image fields of stereoscopic images must have even illumination. If audiences are subjected to uneven illumination intensity of right and left pairs of stereoscopic images, the result for most people will be discomfort. Complimentary colored filters are used in the optical paths of the right and left projected fields, and the resultant additive color mixture is used for evaluation of symmetrical illumination. A means is thus presented for quickly, accurately, and inexpensively calibrating right and left image fields for both equal and even illumination intensity.
