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 0 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 (-► 66).
• Unlike the human eye, the Movie Camera's Auto Focus
System cannot change the focus from a distant to a
close subject instantaneously.
