Explanation of terms

Automatic white balance

White balance adjustment recognises the colour

of light and adjusts so the white colour will

become a purer white. The unit determines the

hue of light that comes through the lens, thereby

judging the recording condition, and selects the

closest hue setting.

This is called automatic white balance

adjustment.

However, since the unit only stores white colour

information under certain light sources,

automatic white balance adjustment does not

function normally under other light sources.

The illustration above shows the range over

which the auto white balance functions.

1) The effective range of automatic white

balance adjustment on this unit

2) Blue sky

3) Cloudy sky (rain)

4) TV screen

5) Sunlight

6) White fluorescent lamp

7) Halogen light bulb

8) Incandescent light bulb

9) Sunrise or sunset

10) Candlelight

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 adjustment

White balance adjustment determines the white

colour under different light sources. By

recognising which is the white colour under

sunlight and which is the white colour under a

fluorescent light, the unit can adjust the balance

among the other colours.

Since the white colour is the reference for all the

colours, the unit can record pictures in a natural

hue if it can recognise the reference colour white.

Auto focus

The lens is moved forward or backward

automatically to bring the subject into focus.

Auto focus has the following characteristics.

≥ Adjusts the focus 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 centre 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

centre 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.
