Panasonic PV-GS250 ª White balance, ª Auto focus, Recording a subject behind dirty or dusty glass

Others

ªWhite balance

The image recorded by the Camcorder may become bluish or reddish under the influence of 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 lamp, the Camcorder can adjust the balance among the other colors.

Since white color is the reference of all colors (light), the Camcorder can record pictures in a natural hue if it can recognize the reference white color.

ªAuto focus

Auto focus automatically moves the focusing lens forward and backward inside the Camcorder 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 a subject with one end located closer to the Camcorder and the other end farther away from it

≥As auto focus adjusts at the center of an image, it may be impossible to focus on a subject that is located in both the foreground and background.

Recording a subject behind dirty or dusty glass

≥The subject behind the glass will not be focused because the focus is on the dirty glass.

Recording a subject that is surrounded by objects with glossy surfaces or by highly reflective objects

≥The recording subject may become blurry because the Camcorder focuses on the objects with glossy surfaces or on highly reflective objects.

Recording a subject in dark surroundings

≥The Camcorder 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.

Recording a subject with little contrast

≥A subject with little contrast, such as a white wall, may become blurry because the Camcorder achieves focus based upon the vertical lines of an image.
