0 Image area on which the Auto Focus Function adjusts
the focus
When you aim the Movie Camera at the subject that you
want to record, the microprocessor determines (based on
the information about the vertical contours in the picture
signal received by the CCD Image Sensor) whether the
subject in the middle of the picture is properly focused. If
not optimally focused, it quickly moves the focusing lens
in tiny steps from the previous focus setting © or © until
the vertical contours of the subject become sharpest ©.
•As this Movie Camera automatically adjusts the focus
based on the information on the subject’s vertical
contours, precise focusing is not possible for subjects
with weak vertical contours 86).
• Unlike the human eye, the Movie Camera’s Auto Focus
System cannot change the focus from a distant to a
close subject instantaneously.
