Auto focus
The lens is moved forward or backward
automatically to bring the subject into focus.
Auto focus has the following
characteristics.
≥ Adjusts so that the vertical lines of a
subject are seen more clearly.
≥ Attempts to bring an object with higher
contrast into focus.
≥ Focuses on the screen center only.
Due to these characteristics, auto focus
does not work correctly in the following
situations. Record pictures in the manual
focus mode.
Recording distant and close-up
objects at the same time
Since the unit focuses on whatever is at
the center of the screen, it is difficult to
bring the background into focus when
close-up objects are placed in focus.
When recording people with distant
mountains in the background, you cannot
focus on both the subject which is
close-up and the objects which are in the
distance.
Recording a subject behind dirty or
dusty window
The subject behind the window will not be
focused because the focus is on the dirty
window.
Similarly, when recording something on
the opposite side of a road with heavy
traffic, a vehicle that happens to pass by
may be brought into focus.
Recording a subject that is
surrounded by objects with glossy
surfaces or by highly reflective
objects
Since whatever is shiny or glistens is
brought into focus, it is hard to focus on
the subject to be recorded. The focus
may become blurry when recording
subjects at the seashore, in night views
or in scenes involving fireworks or special
lights.
Recording a subject in dark
surroundings
The unit cannot focus correctly because
the light information that comes through
the lens decreases considerably.
Recording a fast-moving subject
As the focus lens-inside moves
mechanically, it cannot keep up with a
fast-moving subject.
When, for example, recording a sports
event with fast moving subjects, the focus
may lose its sharpness.
Recording a subject with little contrast
It is easy to bring subjects with a sharp
contrast or vertical lines or stripes into
focus. This means that a subject with little
contrast, such as a white wall, may
become blurry because the unit achieves
focus based upon the vertical lines of an
image.
Concerning MPEG2 motion
pictures
“MPEG” stands for Moving Pictures
Experts Group. It refers to a format for
compressing video.
MPEG2 enables motion pictures to be
played back more smoothly and
attractively by sending the image data at
a rate of 30 frames per second.
(SD Speed Class Rating
Class 2)
This indicates a Class 2 rating in the high
speed standards (SD Speed Class)
stipulated by the SD Card Association for
high speed writing between SD
compatible products and SD Memory
cards.
If you use a Class 2 card compatible with
the SD Speed Class in an SD compatible
product, you can obtain stable recording
by using a SD card conformed with Class
2 or more.
