Auto Focus - Panasonic AG-HSC1UP Operating Instructions Manual

Others
Outside of the effective range of automatic white
balance adjustment, the image will become
reddish or bluish. Even within the effective range
of automatic white balance adjustment, the
automatic white balance adjustment may not
function properly if there is more than one light
source. For light outside the functional automatic
white balance adjustment range, use the manual
white balance adjustment mode.
White balance
The images recorded by the unit may become
bluish or reddish under the influence of certain
light sources. To avoid such phenomena, adjust
the white balance.
White balance adjustment determines the white
color under different light sources. By
recognizing which is the white color under
sunlight and which is the white color under a
fluorescent light, the unit can adjust the balance
among the other colors.
Since the white color is the reference for all the
colors (that make up light), the unit can record
pictures in a natural hue if it can recognize the
reference color white.

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 beach, 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.
