摘要： The image display apparatus comprises: an image processor for outputting image data including plural color component data; a gain corrector for correcting levels of the image data output by the image processor; and an image display device having a plurality of pixels from each of whose pixels light for forming an image exits in accordance with the corrected image data corrected by the gain corrector. The gain corrector corrects the level of at least one of the plural color component data applied to the pixels in accordance with the positions of the pixels such that, when image data representing an image of a prescribed uniform color are output from the image processor, difference in chromaticity of light exiting from the pixels is reduced among the pixels without making luminance of the light exiting from the pixels of the image display device the same at all pixels.

摘要： An apparatus and technique for providing isolation for a signal source utilizing two or more modulators is described. In particular, the apparatus generates a timed sequence of "open gates" that are synchronized to the data signal which permit transmission in a forward direction, and which attenuate a reverse direction signal. Another embodiment attenuates primarily reflected light signals by utilizing a passive waveguide and a modulator. The passive waveguide provides a propagation delay such that signals reflected from its end facet are attenuated by the modulator. The apparatus is suitable for use as an isolator for a light source in a high-speed optical fiber data transmission system.

摘要： A target unit comprises equally spaced and crosswise arranged photoelectric converters responsive to a visible or invisible light pulse beam hitting the unit at an area including a center point for producing output pulses. The converters are disposed on four sides of the cross point, and divided into four adjacent groups, adjacent to the cross point and four remote groups, remote therefrom. The area is capable of covering the adjacent group converters but no more of the remote group ones when the center point coincides with the cross point. Counts of the output pulses for each adjacent group and for the associated remote group are added. The sum for the adjacent and remote group pair is subtracted from the sum for the related pair to drive an indicator for simulating the distance and the azimuth of the center point relative to the cross point.

摘要： A vertical cavity surface emitting laser includes a first semiconductor multilayer reflector, a resonator, and a second semiconductor multilayer reflector. The first semiconductor multilayer reflector is formed on a substrate and is configured by stacking a high refractive index layer having a relatively high refractive index and a low refractive index layer having a relatively low refractive index. The resonator includes an active layer formed on the first semiconductor multilayer reflector. The second semiconductor multilayer reflector is configured by stacking the high refractive index layer and the low refractive index layer. The resonator includes a pair of spacer layers disposed vertically on the active layer and a resonator extension area formed at one side of the pair of spacer layers. The resonator extension area contains a material in which an energy level with a crystal defect is higher than a general energy level without the crystal defect.

摘要： Technology for carrying out a luminance range expansion process is provided. In the technology, the luminance range expansion process is carried out in a manner appropriate to the luminance histogram of image data. Using the white peak value WP which represents the maximum value of luminance and the APL which represents the mean value thereof in the luminance histogram of image data, an expansion coefficient for use in the luminance range expansion process is derived by referring to an expansion coefficient lookup table 210. On the basis of the expansion coefficient, the luminance range expansion process is performed on the image data.
