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, 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) 7) 3 000K 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. 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 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, 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. 132 VQT1N74
