摘要： A handheld imaging device has a data receiver that is configured to receive reference encoded image data. The data includes reference code values, which are encoded by an external coding system. The reference code values represent reference gray levels, which are being selected using a reference grayscale display function that is based on perceptual non-linearity of human vision adapted at different light levels to spatial frequencies. The imaging device also has a data converter that is configured to access a code mapping between the reference code values and device-specific code values of the imaging device. The device-specific code values are configured to produce gray levels that are specific to the imaging device. Based on the code mapping, the data converter is configured to transcode the reference encoded image data into device-specific image data, which is encoded with the device-specific code values.

摘要： Methods are disclosed for adaptive display management using one or more viewing environment parameters. Given the one or more viewing environment parameters, an effective luminance range for a target display, and an input image, a tone-mapped image is generated based on a tone-mapping curve, an original PQ luminance mapping function, and the effective luminance range of the display. A corrected PQ (PQ′) luminance mapping function is generated according to the viewing environment parameters. A PQ-to-PQ′ mapping is generated, wherein codewords in the original PQ luminance mapping function are mapped to codewords in the corrected (PQ′) luminance mapping function, and an adjusted tone-mapped image is generated based on the PQ-to-PQ′ mapping.

摘要： High dynamic range 3D images are generated with relatively narrow dynamic range image sensors. Input frames of different views may be set to different exposure settings. Pixels in the input frames may be normalized to a common range of luminance levels. Disparity between normalized pixels in the input frames may be computed and interpolated. The pixels in the different input frames may be shifted to, or stay in, a common reference frame. The pre-normalized luminance levels of the pixels may be used to create high dynamic range pixels that make up one, two or more output frames of different views. Further, a modulated synopter with electronic mirrors is combined with a stereoscopic camera to capture monoscopic HDR, alternating monoscopic HDR and stereoscopic LDR images, or stereoscopic HDR images.

摘要： Pixels of a display system may comprise light emitting elements whose light output levels are set based on image data as well as background areas whose light reflectance levels are set based on the same image data. These light output levels and/or light reflectance levels may also be adjusted based on an ambient light level. The background areas may comprise light reflective elements which may be controlled individually or as a whole. The light output levels of the light emitting elements and the light reflectance levels of the light reflective elements are configured to generate collectively a pixel value for the pixel dependent on the image data. One or more modulation algorithms may be used to control the energy consumption, dynamic range, color gamut, point-spread function, etc., of the pixels in the display system.
