    摘要: The present invention provides a technique that reduces color non-uniformity in a color image projected and displayed by a projector. The projector that projects and displays the color image includes an illumination optical system, a color light separation optical system, first through third electro-optical devices, a color light synthesizing optical system, and a projection optical system. The projector generally has one or a plurality of light bundle adjustment optical systems provided in one or some of three optical paths, which respectively connect the color light separation optical system with the first through the third electro-optical devices. Each light bundle adjustment optical system regulates size of a light bundle of a selected color light. The technique of the present invention adjusts specific one or plural image signals according to pixel positions of a color image, so that cross sectional luminance distributions of first through the third modulated lights on a light-exiting side of the color light synthesizing optical system have substantially the same gradients at least when the image of interest to be projected and displayed is a white image. This arrangement effectively reduces color non-uniformity in the resulting color image, due to the presence of the light bundle adjustment optical system.

    摘要: A liquid crystal device that modulates light in accordance with supplied image information comprises a plurality of pixels arranged in a matrix, each pixel having an opening to allow passage of light, and an array of micro-lenses arranged in a matrix that divides illumination light into a plurality of partial light beams and converges the light beams to a light incidence plane of the pixels. In the liquid crystal device, the characteristics of the micro-lenses are adjusted to increase a proportion of light exiting from the opening of each pixel substantially parallel to a clear viewing direction of the liquid crystal device compared to a proportion of light parallel to other directions. Each micro-lens is positioned so that a line connecting the optical center of the micro-lens to the center of the incident surface of the corresponding pixel is substantially parallel to the clear viewing direction.

    摘要: A mixed dual frequency generating system for generating a digital FSK signal or a signal including two mixed frequencies includes a ROM which stores in consecutive addresses sampled data obtained by sampling a sine wave at a sampling frequency. The mixed dual frequency generating system also includes a data extracting circuit for extracting the sampled data from the ROM at the sampling frequency using an extracting step number. An output data fixing circuit changes alternate data extracted from the ROM to data "O", so that a signal having two mixed frequencies can be obtained.
