Explanation of terms Automatic white balance White balance adjustment recognizes the color of light and adjusts so the white color will become a purer white. The unit determines the hue of light that comes through the lens and white balance sensor, 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 color information under several light sources, automatic white balance adjustment does not function normally under other light sources. 10 000K 9 000K 8 000K 7 000K 6 000K 5 000K 1) 4 000K 2) 3) 4) 5) 6) 3 000K 7) 8) 2 000K 9) 10) 1 000K 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.

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. 107 VQT0X39
