摘要： Methods and apparatus according to various aspects take as input image data in a lower-dynamic-range (LDR) format and produce as output enhanced image data having a dynamic range greater than that of the input image data (i.e. higher-dynamic range (HDR) image data). In some embodiments, the methods are applied to video data and are performed in real-time (i.e. processing of video frames to enhance the dynamic range of the video frames is completed at least on average at the frame rate of the video signal).

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： Aspects of the invention provide systems and methods for converting a digital image represented in a lower bit depth representation to a higher bit depth representation. A saturation region is identified, where a color model value of the pixels in the saturation region is above an upper saturation threshold or below a lower saturation threshold. The color model value for each pixel in the saturation region is then adjusted by a corresponding adjustment. The magnitude of the adjustment for each pixel is based on characteristics of the image data.

摘要： An optical structure placeable between a backlight array of point light sources and a planar display. The structure distributes light emitted by the point light sources to uniformly illuminate the plane of the display, without introducing significant viewing parallax. The emitted light is partially collimated within a preferred angular viewing range, maximizing the display's luminance when viewed from the normal direction. The structure is highly reflective, such that a substantial portion of any non-emitted light rays are internally reflected by the structure, increasing the likelihood that those rays will be subsequently emitted by the structure.

摘要： Longitudinally adjacent plane mirrors (106-114) are pivotally interconnected in a columnar array (56) by non-stretching linkages (120) which constrain movement of the mirrors such that their normal vectors (115) remain parallel. Pivotable couplings (122, 124) in two mirrors permit movement of the mirrors with respect to mutually perpendicular axes (x, y) and prevent movement of the mirrors with respect to a third axis (z). Two actuators (117A, 117B) coupled to one of the pivotable couplings controllably move a selected mirror with respect to the mutually perpendicular axes (x, y). A first frame (116) couples the mirror columns together so that movement of the selected mirror moves all the mirrors in unison. The actuators controllably move the mirrors to orient the normal vectors such that the mirrors specularly reflect incident light in a preselected direction.
摘要翻译：纵向相邻的平面镜（106-114）通过非拉伸连杆（120）以圆柱形阵列（56）枢转地互连，这限制了反射镜的运动，使得其法向矢量（115）保持平行。两个反射镜中的可转动联轴器（122,124）允许反射镜相对于相互垂直的轴线（x，y）移动，并防止反射镜相对于第三轴线（z）移动。联接到可枢转联接器之一的两个致动器（117A，117B）可相对于相互垂直的轴线（x，y）可控地移动所选择的反射镜。第一框架（116）将镜柱连接在一起，使得所选择的镜子的运动一致地移动所有的镜子。执行器可控制地移动反射镜以使法向矢量定向，使得反射镜以预选的方向镜面反射入射光。

摘要： A reflective display having a plurality of transparent hemi-beads (120), each having a reflective region (80) surrounding a non-reflective region (82). Each hemi-bead has an associated light absorptive fluid droplet (122) having a normally relaxed shape contacting the non-reflective region, thereby frustrating total internal reflection of light rays at the droplet/hemi-bead interface. An electrical potential is selectably applied across selected droplets. Application of the electrical potential across a droplet deforms the droplet away from the hemi-bead associated with the droplet, such that light rays (158) incident on the non-reflective region are refracted toward substrate (124) and reflected back through hemi-bead (120) in an approximately opposite direction (166); and such that light rays (162) incident on the reflective region are semi-retro-reflected (168). Removal of the electrical potential allows the droplet to resume the relaxed shape.

摘要： A display comprises a backlight comprising a plurality of individually-controllable light emitters, a light modulator comprising a plurality of individually-controllable elements, and, a retro-reflective optical layer positioned between the backlight and the light modulator. The retro-reflective optical layer is configured to pass light incident thereon at an angle with respect to a normal to the retro-reflective optical layer of less than a threshold angle φ, and reflect light incident thereon at an angle with respect to a normal to the retro-reflective optical layer of greater than φ in a direction opposite and generally parallel to an incoming direction of incident light.
