    摘要: Apparatus and methods are provided that employ one or more of a variety of techniques for reducing the time required to display high resolution images on a high dynamic range display having a light source layer and a display layer. In one technique, the image resolution is reduced, an effective luminance pattern is determined for the reduced resolution image, and the resolution of the effective luminance pattern is then increased to the resolution of the display layer. In another technique, the light source layer's point spread function is decomposed into a plurality of components, and an effective luminance pattern is determined for each component. The effective luminance patterns are then combined to produce a total effective luminance pattern. Additional image display time reduction techniques are provided.

    摘要: Methods and systems process image data made up of a series of frames for displaying on a dual modulation display system having a first modulator disposed to illuminate a second modulator. A first modulation signal and a luminance map are not calculated for every frame. Instead, certain frames referred to as “key frames” are used to provide the first modulation signal and the luminance map for at least some other frames.

    摘要: A method for capturing multiple sets of image data with an electronic camera having a shutter and an electronic shutter for selectively allowing light to reach an image sensor comprises opening the shutter and the electronic shutter, allowing light to reach the image sensor for a first exposure time, closing the electronic shutter, reading out pixel data captured during the first exposure time, allowing light to reach the image sensor for a second exposure time, and, reading out pixel data captured during the second exposure time. The method may be used to obtain multiple differently exposed images of a scene for combination into a high dynamic range image.

    摘要: A display incorporates both narrow-band light emitters and broadband light emitters. The light emitters are controlled to display images according to image data. The narrow-band light emitters can be used to provide highly saturated primary colors. Light from the broadband light sources may be mixed with the broadband light. This can reduce metamerism failures arising from variations in the characteristics of the eyes of observers.

    摘要: Liquid Crystal Display (LCD) flare is reduced by adjusting a backlight to a level where the LCD flare is not visible, and then introducing a simulated veiling glare. The glare is further adjusted by the backlight simulation to hide the geometry (e.g., Light Emitting Diode (LED) array) of the backlight. The reduction is performed, for example, by processing signals for driving the backlight and a front modulator in a dual modulation display device.
