    摘要： Several embodiments of projection systems are disclosed that comprise a plurality of controllable emitters, each said emitter providing light for a light path; a plurality of first optical elements, each said first optical element receiving light from one of said emitters; a controllable modulator receiving light from said plurality of first optical elements; a plurality of conduits, each said conduit disposed over a portion of said controllable modulator; a plurality of second optical elements, each of said second optical elements receiving light from at least one of said plurality of conduits, and a controller for sending control signals to said controllable emitters and said controllable modulator. The illumination from the emitters may form a plurality of overlapping areas of illumination upon a projection screen where the image is intended to be formed.

    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 high dynamic range image can be recovered from a full-resolution lower-dynamic-range image and a reduced-resolution higher-dynamic-range image. Information regarding higher spatial frequencies may be obtained by extracting high spatial frequencies from the lower-dynamic-range image. In some embodiments an approximate impulse-response function is determined by comparing the higher- and lower-dynamic range images. A scaling image obtained by applying the impulse-response function to a high-frequency band of the lower-dynamic range image is combined with an upsampled higher-dynamic range image to yield a reconstructed image.

    摘要： Representation and coding of multi-view images using tapestry encoding are described. A tapestry comprises information on a tapestry image and a world coordinates map associated with the tapestry image, each of which may contain information from one or more perspectives of a scene. Perspective images of a scene can be generated from the tapestry image and the world coordinates map.

    摘要： An electronic camera comprises two or more image sensor arrays. At least one of the image sensor arrays has a high dynamic range. The camera also comprises a shutter for selectively allowing light to reach the two or more image sensor arrays, readout circuitry for selectively reading out pixel data from the image sensor arrays, and, a controller configured to control the shutter and the readout circuitry. The controller comprises a processor and a memory having computer-readable code embodied therein which, when executed by the processor, causes the controller to open the shutter for an image capture period to allow the two or more image sensor arrays to capture pixel data, and, read out pixel data from the two or more image sensor arrays.
