1. A camera field indicating method for a camera including a light sensor, imaging optics, and an extended light source situated near the light sensor and sharing the imaging optics, the method comprising:

  • sensing incoming light via the imaging optics and the light sensor;

    intermittently activating the extended light source when the light sensor does not need to sense incoming light such that a projection of the extended light source through the imaging optics matches a field of view of the light sensor; and

    patterning the projection of the extended light source by spatially patterning the extended light source such that a color of the projection, as perceived by a user, is different depending on a position of a user in the zone of a frame of the image to indicate to the user the position of the user in the zone.
