    摘要: Projector display systems comprising a light dimmer and first modulator are disclosed. The light dimmer may comprise an adjustable iris, adjustable light sources and/or LCD stack that is capable of lowering the luminance of the light source illuminated the first modulator. The first modulator may comprise a plurality of analog mirrors (e.g. MEMS array) and the second modulator may comprise a plurality of mirrors (e.g., DMD array). The display system may further comprise a controller that sends control signals to the light dimmer and first modulator. The display system may render a desired dynamic range for rendering a projected image by a combination of such control signals.

    摘要: A light source drive device includes a supply unit that supplies a high-frequency first drive signal and a second drive signal whose frequency is lower than a frequency of the first drive signal to a discharge lamp which has a pair of electrodes, and a control unit that controls the supply unit so that the second drive signal is supplied during a second period after the first drive signal is supplied during a first period and the second period is lengthened as a voltage between the pair of electrodes is increased. It is preferable that the second period be longer than two minutes.

    摘要: In some examples, the intensity of an image projected onto a surface at an oblique angle may be controlled to equalize the intensity, and thereby to eliminate from the image perceptible variations in brightness. For instance, a first distance to a closer portion of the image and a second distance to a farther portion of the image may be used to determine an amount of change to be made to the intensity of at least one portion of the image. In some implementations, a filter may be used to control changes to the intensity of the image. In other implementations, the image information may be modified, such as on a pixel level, to control the intensity of the image.

    摘要: An object guide system includes a plurality of light projecting devices, at least one image capture device, a control device electrically coupled with the light projecting devices, and a display unit electrically coupled with the at least one image capture device and the control device. When an object enters an operation space, a projected information is imaged on the object. Then, the at least one image capture device captures the cross information of the operation space and the three-dimensional position information of the object. Then, the control device calculates the coordinates of the object that is moving in the operation space. Thus, after the at least one image capture device captures the cross information of the operation space and the three-dimensional position information of the object, the object guide system proceeds interactive and guiding operations.

    摘要: An image projection apparatus includes a light source, a color wheel, a controller. The controller controls, in a first mode, electric power supplied to the light source at a timing of a first color filter being irradiated with light from the light source to be a value higher than electric power supplied to the light source at a timing of a second color filter corresponding to a color having lower visibility than a color of the first color filter being irradiated with the light from the light source. Furthermore, the controller controls, in a second mode, the electric power supplied to the light source at the timing of the first color filter being irradiated with the light from the light source to be a value lower than the electric power supplied to the light source at the timing of the second color filter being irradiated with the light.
