Abstract: A method includes sensing a plurality of luminance values associated with ambient light from a physical environment. The plurality of luminance values quantifies the ambient light arriving at a see-through display. The method includes obtaining a plurality of semantic values respectively associated with a plurality of portions within image data. The plurality of portions includes a first portion of the image data and a second portion of the image data. The method includes identifying a first one of the plurality of semantic values that satisfies a criterion. The first one of the plurality of semantic values is associated with the first portion of the image data. The method includes mapping, based on a function of a portion of the plurality of luminance values, the image data to predetermined display characteristics of the first portion of the image data within a performance threshold.

Abstract: Various implementations disclosed herein adjust the luminance values of an image to improve the appearance of the image on an augmented reality device. In some implementations, the luminance values of an image are adjusted so that the image can be displayed on an augmented reality device (e.g., with background luminance) such that the image will be perceived more similarly to how the image would be perceived otherwise (e.g., on a device without background luminance). In some implementations, an image is adjusted based on an estimate of human perception of luminance that is not linear.

Abstract: A head-mounted device may have an inner display that displays images for a user and an outer display that informs nearby people of the status of the user and inner display. For example, the outer display may display an image of a face, an abstract layer, or both, depending on whether the inner display is operating in passthrough mode, mixed reality mode, or virtual reality mode. An ambient light sensor in the head-mounted device may be used to measure the brightness and color of ambient light. The white point of the face layer on the outer display may be adapted to the color of ambient light, whereas the white point of the abstract layer on the outer display may remain fixed. The white point of a display may be a correlated color temperature setting (e.g., measured in degrees Kelvin) that determines the warmth or coolness of displayed colors.

Abstract: A method includes obtaining rendered image data that includes a representation of an object for display using a see-through display. The see-through display permits ambient light from a physical environment through the see-through display. The method includes sensing a plurality of light superposition characteristic values associated with the ambient light that quantifies the ambient light. The method includes determining a plurality of display correction values associated with the electronic device based on the plurality of light superposition characteristic values and predetermined display characteristics of the representation of the object. The method includes generating, from the rendered image data, display data for the see-through display in accordance with the plurality of display correction values in order to satisfy the predetermined display characteristics of the representation of the object within a performance threshold.

Abstract: A method includes sensing a plurality of luminance values associated with ambient light from a physical environment. The plurality of luminance values quantifies the ambient light arriving at a see-through display. The method includes identifying respective portions of the plurality of luminance values, across the see-though display, based on corresponding portions of rendered image data. The method includes modifying one or more of the respective portions of the plurality of luminance values based on a function of predetermined display characteristics associated with the rendered image data, in order to generate one or more modified portions of the plurality of luminance values. The method includes modifying the corresponding portions of the rendered image data in order to generate display data, based on the one or more modified portions of the plurality of luminance values. The method includes displaying, on the see-through display, the display data.
