LSQT1337 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 certain 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 4 000K 3 000K 2 000K 1 000K 2) 1) 3) 4) 5) 6) 7) 8) 9) 10) 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 LSQT1337 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 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 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, at 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.
