Face Detection
When the camera is pointed at a human face in the
shooting modes listed below, the camera
automatically detects the face and focuses on it. When
the camera detects more than one face, the double
border (focus area) is displayed around the face that is
focused on, and single borders around the others.
• In I_1 (auto) mode, if no faces are detected when the shutter-release button is
pressed halfway, the camera automatically selects one (or more) of the nine
focus areas containing the subject closest to the camera.
• In Scene auto selector scene mode, the focus area changes depending on the
selected scene.
• In Portrait and
Night portrait
scene modes or smart
portrait mode,
if no faces
are detected when the shutter-release button is pressed halfway, the camera
will focus on the sub]act at the center of the frame.
• Tap a face framed by a single border to change the focus area to that face
(_ 45,50).
• In subject tracking mode, sub]ect tracking begins when a detected face framed
by a border is tapped ([]_ 48).
_1_ Notes on the Face Detection Function
• The camera may be unable to detect faces in the following situations:
When faces are partially hidden by sunglasses or other obstructions
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 cases, including those noted in "Autofocus" (_ 31), autofocus may not perform as
expected, and the subject may not be in focus despite the fact that the double border glows
green. Should this occur, refocus on another subject positioned at the same distance from the
camera as the actual portrait subject ([._ 52).
[] Notes on Pictures Including Detected Faces
• When pictures in which a face was detected during shooting are played back, the pictures will be
automatically rotated for playback display according to the orientation of the face detected
except pictures that were taken using Continuous, BSS, and Multi-shot 16 ([.]]_) 54), or the
subject tracking function (_ 48),
• in full frame playback mode, the picture will be enlarged with the face detected during shooting
at the center of the monitor when the zoom control is rotated to T (c{) (_ 84) except pictures
that were taken using Continuous, BSS, and Multi-shot 16 (_ 54), or the subject tracking
function (_ 48).
