Notes About Face Detection
• The camera’s ability to detect faces depends on a variety of factors, including the direction in
which the faces are looking. Additionally, the camera may be unable to detect faces in the
following situations:
- When faces are partially hidden by sunglasses or otherwise obstructed
- When faces take up too much or too little of the frame
• When the frame includes more than one face, the faces detected by the camera and the face on
which the camera focuses depend upon a variety of factors, including the direction in which the
faces are looking.
• In some rare cases, such as those described in “Subjects Not Suitable for Autofocus” (
A77), the
subject may not be in focus even though the double border turns green. If the camera does not
focus, try focus lock shooting (
A78).
