    摘要: Disclosed is a light guiding valve apparatus including an imaging directional backlight, an illuminator array and an observer tracking system arranged to achieve control of an array of illuminators which may provide a directional display to an observer over a wide lateral and longitudinal viewing range, wherein the luminous intensity of optical windows presented to the observer as viewing windows is controlled dependent on the lateral and longitudinal position or speed of an observer. Further an optical window control system may comprise detection of an observer's hand. An image control system may comprise a method to provide an image that can be switched from a first mode with a first brightness into a second mode with a high brightness region and low brightness region, where the brightness of the second low brightness region is matched to the first brightness.
