Personalized display brightness based on pupil size

A device, comprising:

• one or more memories;
• and
• one or more processors, coupled to the one or more memories, configured to:
• obtain a brightness setting of a display screen associated with the device for a user based at least in part on:
• displaying first calibration content that includes one or more first calibration frames with a first background that approximately corresponds to white, and modifying a luminance of the display screen of the device while displaying the first calibration content until a pupil size of the user satisfies a first target pupil size, and
• displaying second calibration content that includes one or more second calibration frames with a second background that approximately corresponds to black, and modifying the luminance of the display screen while displaying the second calibration content until the pupil size of the user satisfies a second target pupil size;
• calculate a metric value based at least in part on pixel values of content to be displayed;
• adjust the luminance for the display screen based at least in part on the metric value and in accordance with the brightness setting;
• and
• display, via the display screen and using the adjusted luminance, the content.

A non-transitory computer-readable medium storing a set of instructions, the set of instructions comprising:

• one or more instructions that, when executed by one or more processors of a device, cause the device to:
• calibrate a brightness setting of the device for a user based at least in part on:
• displaying first calibration content that includes one or more first calibration frames with a first background that approximately corresponds to white while adjusting a first brightness value of a display screen of the device to be a first calibrated brightness value that achieves a first target pupil size of the user,
• displaying second calibration content that includes one or more second calibration frames with a second background that approximately corresponds to black while adjusting a second brightness value of the display screen of the device to be a second calibrated brightness value that achieves a second target pupil size of the user, and
• displaying a user input option to adjust at least one of the first calibrated brightness value or the second calibrated brightness value;
• calculate a metric value based at least in part on pixel values of content to be displayed;
• and
• display, via the display screen and using an adjusted brightness value, the content, wherein the adjusted brightness value is based at least in part on the metric value and is adjusted in accordance with the brightness setting.

An apparatus, comprising:

• means for calibrating a brightness setting of the apparatus for a user based at least in part on:
• displaying first calibration content that includes one or more first calibration frames with a first background that approximately corresponds to white and modifying a luminance of a display screen of the apparatus while displaying the first calibration content until a pupil size of the user satisfies a first target pupil size, and
• displaying second calibration content that includes one or more second calibration frames with a second background that approximately corresponds to black, and
• modifying the luminance of the display screen while displaying the second calibration content until the pupil size of the user reaches a second target pupil size;
• means for calculating a metric value based at least in part on pixel values of content to be displayed by the apparatus;
• and
• means for adjusting the luminance for the display screen based at least in part on the metric value and in accordance with the brightness setting.
