Description
CMOS CMOS stands for Complementary Metal-Oxide Semiconductor. CMOS chips are substantially less expensive and problematic to fabricate, and they have significantly lower power requirements than CCDs. Also, CCDs have the single function of registering where light falls on each of the hundreds of thousands of sampling points. CMOS can be loaded with a host of other tasks, such as analogue-to-digital conversion, load signal processing, handling white balance and camera controls, and more. It's also possible to increase CMOS density and bit depth without bumping up the cost. Frame Per Second (fps) Frames Per Second is a measurement of how much information is used to store and display motion video. The term applies equally to film video and digital video. Each frame is a still image; displaying frames in quick succession creates the illusion of motion. The more frames per second (fps), the smoother the motion appears. Television in the U.S., for example, is based on the NTSC format, which displays 30 interlaced frames per second (60 fields per second). In general, the minimum fps needed to avoid jerky motion is about 30. Some computer video formats, such as AVI, provide only 15 frames per second. USB Universal Serial Bus is a new external bus standard that supports data transfer rates of 12 Mbps. A single USB port can be used to connect up to 127 peripheral devices, such as mice, modems, and keyboards. USB also supports Plug- and-Play installation and hot plugging. With USB, you can add and remove devices to a computer while the computer is running and have the operating system automatically recognize the change. You can plug in a device and play with it, without worrying about setting DIP switches, jumpers, and other configuration elements. Resolution The resolution signifies the number of dots (pixels) on the entire screen. For example, a 640-by-480 pixel screen is capable of displaying 640 distinct dots on each of 480 lines, or about 300,000 pixels. This translates into different dpi measurements depending on the size of the screen. For example, a 15-inch VGA monitor (640x480) displays about 50 dots per inch. Printers, monitors, scanners, and other I/O devices are often classified as high resolution, medium resolution, or low resolution. The actual resolution ranges for each of these grades is constantly shifting as the technology improves. Focus It is the range that the PC Cameras can capture and focus. Lens The lens that PC Cameras use for capturing the image. Still Image Capture 1 This feature allows the user to capture the still image right from the PC camera. It is like having an extra camera function to the video camera. Automatic White Balance The PC Cameras automatically change the white balance for the image. Hence, the image will not be too dark or pale. Internet Ready The product is ready to be used for the Internet.
