摘要： Systems and methods of image processing are provided for a display having a light source modulation layer and a display modulation layer. A section of a perceptual curve, such as a DICOM curve, is extracted for each frame of image data, based on a profile of expected luminance on the display modulation layer from light emitted by the light source modulation layer. The section of the perceptual curve may be used to determine a desired-total response curve which maps display modulation layer input control values to corresponding output luminance values. The desired-total response curve and a display modulator-specific response curve may be applied to image data to generate control values for driving the display modulation layer.

摘要： Image data is encoded for distribution in a lower bit-depth format. The image data has a range that is less than a maximum range and is mapped to the lower bit depth format using a mapping such that a ratio of a range of the lower bit depth representation to a maximum range of the lower bit depth representation is greater than a ratio of the range of the image data to a maximum range of the image data. Metadata characterizing the mapping is associated with lower bit depth representation. The metadata may be used downstream to reverse the mapping so that tonal detail is better reproduced.

摘要： Embodiments of the invention relate generally to generating images with an enhanced range of brightness levels, and more particularly, to facilitating high dynamic range imaging by adjusting pixel data and/or using predicted values of luminance, for example, at different resolutions. In at least one embodiment, a method generates an image with an enhanced range of brightness levels. The method can include accessing a model of backlight that includes data representing values of luminance for a number of first samples. The method also can include inverting the values of luminance, as well as upsampling inverted values of luminance to determine upsampled values of luminance. Further, the method can include scaling pixel data for a number of second samples by the upsampled values of luminance to control a modulator to generate an image.

摘要： An injection valve for injecting fuel into a working chamber of an internal combustion engine includes a valve seat on the working chamber and a valve needle movable relative to the valve seat between a closed position and an open position. The valve seat has an inner tapered surface and the valve needle has an outer tapered surface, such that, when in the open position, the inner tapered surface of the valve seat and the outer tapered surface of the valve needle define a flow passage that decreases in diameter toward the working chamber. The valve needle terminates at an atomizing surface. The atomizing surface is at an angle of between 45 and 135 degrees relative to the outer tapered surface, and the flow passage directs the fuel onto the atomizing surface.

摘要： Embodiments of the invention relate generally to computer-based image processing, and more particularly, to systems, computer-readable mediums, methods, and apparatuses to operate a rear modulator in a high dynamic range display to, among other things, characterize input images into pixel characteristics which may be data-reduced representations of a group of pixels corresponding to the input image, and to relate a modulation value intensity image to a weighted combination of the pixel characteristics. The modulation value intensity image may be used to derive a rear modulator drive signal, which, turn, may be configured to control one or more modulating elements to generate a low resolution image of the input image at the rear modulator.
