    Abstract: Methods for gamut mapping and boosting a color saturation of a color signal having multiple colors and a color value for each color. An example method includes mapping each color from a first to a second color space, adjusting each color in the mapped color signal including boosting a color saturation; determining a maximum color value of the color signal; and, in response to a determining that the maximum color value exceeds a maximum displayable color value, setting the color value of the color having the maximum color value to be equal to the maximum displayable color value and scaling color values of colors not having the maximum color value.

    Abstract: A system and method for gamut mapping out-of-gamut signals. A method includes adjusting each color in a color signal, determining a maximum color value of the color signal, in response to a determining that the maximum color value exceeds a maximum displayable color value, scaling color values of colors not having the maximum color value, and setting the color value of the color having the maximum color value to be equal to the maximum displayable color value. The method further includes leaving the color values of the colors in the color signal unchanged in response to a determining that the maximum color value does not exceed the maximum displayable color value. The scaling of color values not equal to the maximum color value results in a maintaining of a proper hue of the color signal, thereby not introducing color artifacts and other forms of color noise.

    Abstract: A system comprises an eyewear device that includes a frame, a temple connected to a lateral side of the frame, a fingerprint sensor, and a sensing circuit. The fingerprint sensor includes an input surface to receive input of a finger skin surface. The sensing circuit is configured to track a pattern of fingerprint ridges of the finger skin surface on the input surface. Execution of programming by a processor configures the system to perform functions to track, via the sensing circuit, the pattern of fingerprint ridges of the finger skin surface on the input surface; generate a fingerprint image having the tracked pattern of fingerprint ridges; extract fingerprint features from the fingerprint image; and authorize the user to utilize the eyewear device based on the extracted fingerprint features.

    Abstract: System and method for generating multiprimary signals for use in display devices. A preferred embodiment comprises converting a color signal into an intermediate color space representation of the color signal, converting one of a plurality of multiprimary signals that is a representation of the color signal into an intermediate color space representation of the multiprimary signal, computing a quality measure of the intermediate color space representations of the color signal and the multiprimary signal, repeating the converting of a multiprimary signal and the computing for the remainder of the plurality of multiprimary signals, and selecting a multiprimary signal that optimizes the quality measure. The quality measure can consider requirements such as those minimizing a distance between the color signal and the multiprimary signal, an energy change as well as a phase change between the multiprimary signal and its neighbors, all leading to improved image quality.

    Abstract: The present disclosure relates to systems and processes for automatically adjusting the white point of displayed images to account for changes in ambient light. In one embodiment, a display system includes a display device having sensors for recording the red (R), green (G) and blue (B) values for ambient light and measuring the intensity of such light. The sensors feed these values into a processor, which calculates R, G, B gain values to be applied to the video input R, G, B values. In this manner, the display device can account for changes in ambient light to adjust the perceived white point accordingly. Related methods for automatically adjusting the white point of a perceived image are also described.
