Displaying image data based on ambient light

A head-mountable device (HMD) comprising:

• a user-facing image sensor;
• a scene-facing display;
• one or more scene-facing sensors;
• a non-transitory memory;
• one or more processors;
• and
• one or more programs stored in the non-transitory memory, which, when executed by the one or more processors, cause the HMD to:
• capture, via the user-facing image sensor, first image data that corresponds to a portion of a face of a user wearing the HMD;
• determine, based on data captured by the one or more scene-facing sensors, whether a person other than the user is within a threshold distance of the HMD;
• and
• in response to determining that a person other than the user is within the threshold distance of the HMD, display, on the scene-facing display, second image data depicting the portion of the face of the user and that is generated by modifying the first image data based on a current ambient light condition to match a visual appearance of another portion of the face of the user that is viewable by the person.
