_1_ Notes on Face Detection
• The camera's ability to detect faces depends on a variety of factors, including whether or not the
subject is facing the camera. 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
subject is facing.
• in some rare cases, such as those described in "Autofocus" (_33), the subject may not be in focus
even though the double border turns green, if the camera does not focus, try "Focus Lock"
(_33).
[] Viewing Pictures Taken Using Face Detection
• During playback, the camera automatically rotates images according to the orientation of the
faces that were detected at the time of shooting, Pictures taken when using Continuous (_54)
or Auto bracketing (_73) are not rotated.
• When zooming in on an image displayed in full frame playback mode by rotating the zoom
control toward T (°0, the image is enlarged at the center of the face that was detected during
shooting (_35), Pictures taken when using Continuous (_54) or Auto bracketing (_73) are
not displayed in this way,
