Using Face Detection
In the following shooting modes, the camera uses face
detection to automatically focus on human faces. If the
camera detects more than one face, a double border is
displayed around the face that the camera will focus
on, and single borders are displayed around the other
faces.
• When using Face priority , if you press the shutter-release button halfway while no faces are
detected or while framing a shot with no faces in it, the camera automatically selects the focus
areas (up to nine) that contain the subject closest to the camera.
• When Scene auto selector is selected, the focus area changes depending on which scene the
camera selects.
• If no faces are detected when the shutter-release button is pressed halfway in Portrait or Night
portrait scene mode, the camera will focus on the subject at the center of the frame.
• When
a
(smile timer) is selected, if you press the shutter-release button halfway while no faces
are detected, the camera will focus on the subject at the center of the frame.

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” (
A
29), the subject may not be in focus
even though the double border turns green. If the camera does not focus, try “Focus Lock” (
A
81).

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 (except for pictures taken using
Continuous
(
A
55) or Exposure bracketing (
A
55)).
• When zooming in on an image displayed in full-frame playback mode by rotating the zoom
control toward
g
(
i
), the image is enlarged at the center of the face that was detected during
shooting (
A
31) (except for pictures taken using Continuous (

(
