Touch & Track
When recording a group of people using face detection, the camcorder
will automatically detect one person as the main subject. You can use
Touch & Track to tell the camcorder to track and optimize settings for a
different person. You can also use Touch & Track to always keep in
focus other moving subjects, such as pets or moving vehicles.
Operating modes:
1 Make sure face detection is activated (A 100).
Face detection is always activated in
2 Point the camcorder at a moving subject and touch the subject on
the touch screen.
• A white double frame will appear around the subject and track it as it
moves.
• Touch [Cancel £] to remove the frame and cancel the tracking.
NOTES
• Touching somewhere with a color or pattern unique to the subject will
make it easier to track. However, if there is another subject in the vicinity
that shares similar characteristics to the selected subject, the cam-
corder may start tracking the incorrect subject. Touch the screen again
to select the desired subject.
• In certain cases, Touch & Track may not be able to track the subject.
Typical examples include:
- Subjects extremely small or large in relation to the overall picture.
- Subjects too similar to the background.
- Subjects lacking sufficient contrast.
- Fast moving subjects.
- When shooting indoors with insufficient lighting.
