Abstract: A processing pipeline and method for mixed reality systems that utilizes selective auto-exposure for a region of interest in a scene based on gaze and that compensates exposure for the rest of the scene based on ambient lighting information for the scene. Images may be generated for display that provide an exposure-compensated, foveated high dynamic range (HDR) experience for the user.

Abstract: A display calibration system may include a first electronic device that includes an ambient light sensor and a display to be calibrated in a second electronic device. The first electronic device may generate test patterns to be displayed on the display. The ambient light sensor may receive light emitted from the display based on the test patterns to generate display color space data. The first electronic device may generate calibration data for the display based on the display color space data and a target reference color space. The second electronic device may store the calibration data and use the calibration data to generate more accurate images. Because the first electronic device may include other functionalities other display calibration, specialized display calibration equipment may be omitted. Additionally, a third electronic device that acts as an intermediary between the first and second electronic devices.
