[. . . ] A 300MHz Intel ® Pentium® CPU will show videos (especially those with higher resolutions and pixel depth) at higher frame rates. Graphics Display Card ­ Fast display cards and graphics accelerators can greatly increase the quality of videos shown on your screen. USB Configuration ­ When the USB Web Camera is the only USB device connected to your computer, it will be able to send image data to your computer faster than if there are other USB devices present. Video Source or Video Settings The video source dialog box allows you to control the image quality provided by your camera. Most applications allow you to access a `Video Source' or `Video Setting' window similar to the one shown below. Items in the above Video Source windows are described as follows: 7 Saturation ­ this setting controls the richness of colors shown by the camera. Brightness ­ this setting controls how bright an image or video will appear. Contrast ­ this setting adjusts the tonal range of an image by lowering mid-tone values and increasing values for high and low tones. For example, use contrast to eliminate noise or shading on black & white and grayscale videos or images or to clean-up color ones. Auto Exposure ­ this setting lets you change the electronic shutter speed. Light Source ­ this setting allows you to select the type of light source you are using. Auto White Balance ­ this setting allows you to adjust how much white will be in the Red, Green and Blue color channels. Checking the Auto box sets the amount of white for each color to predefined settings based on the type of light source. Light Frequency ­ this setting allows you to select the correct light frequency used in your country, you will either choose 50Hz or 60Hz. Please note that many of the above settings operate the same as those on a normal color TV or computer monitor. Proper room lighting is critical for correct functioning of the USB Web Camera. If you are getting dull or dark images, or if the color is poor, try increasing the ambient light in the room or turn off the light behind the subject, or try lighting the subject directly. If you cannot use your camera in a naturally well-lit setting, then a desk lamp or some other artificial light source must be used. Lighting Settings Some applications may also allow you to adjust light settings other than those shown above. We have defined some commonly used terms which may appear in software programs you are using: Lighting Modes - Your camera normally operates in normal mode; however, you can switch it to dark mode when there is too much light or bright mode when light is dim. Banding Filter - If you are in a room lit by fluorescent lighting, then please check that the Banding Filter is being used, if present. Depending on the fluorescent lighting system used in your country, you will either choose a filter type of 50Hz (Europe, Asia) or 60Hz (North America). Color Temperature - The USB Web Camera's default is normal mode, but you can switch it to cool when your light source tends to be red or switch it to warm when your light source tends to be blue. Compression Control - Compression control lets you adjust the frame rate. The USB Web Camera is initially set to use the lowest compression setting, but choosing high compression mode may help speed up the rate of transmission. Audio Source and Settings (VGA Only) Your camera comes with a built-in microphone which allows you to talk without an additional microphone. In "Control Panel" of "My Computer", select "Sounds and Multimedia", change the "Default device" from "Sound recording" to "PC Camera" for XP users or USB (VGA) Camera for 98, 2000, and ME users. 8 2.
