    摘要: A method and system providing dynamic contrast control in scanning line color display systems, and particularly a method and system comprising at least two modulator units is disclosed. One modulator unit is for modulating pixel information in a line to be displayed while the other one provides illumination intensity control over different pixel areas or clusters of pixels of said same line to be displayed by using a tunable diffractive grating element (TDG) in the illumination path to provide image source dependent active brightness level control, i.e. ‘dynamic contrast’, as well as a shutter function for pixels off transition periods.

    摘要: Image stabilization devices and methods are disclosed. In various embodiments, image stabilization is achieved by altering the direction of the optical axis through a flexible lens body by activating actuators attached to the flexible lens body, wherein the amount of applied voltages onto the actuators are proportional to signals provided by motion sensors sensing yawing and pitching movements, respectively.

    摘要: Doubling the resolution of images in a line scan projection system is possible without doubling the length of the modulator or changing the size of the pixels. By arranging an additional pixel row in the modulator, and merging the rows together with half a pixel offset in both directions in the projected image, the resolution may be effectively doubled without significantly increasing the size or speed requirement for the modulator itself.
