Digital video recording system uses a digital video signal. Based on forms of image capture, digital video cameras are of two types: interlaced and progressive scan is. Technology interlaced camera, the odd lines are scanned first and then the even lines are scanned. Even the odd lines are scanned, and so on. A number of odd or even lines, as a field, and a frame is a combination of two successive opposite parity fields. In progressive scan digital video camera, each frame is encoded as separate fields, which included both identical. So interlaced video recordings of the same fields twice per second progressive video, if both are working for the same number of frames per second. This is the cause for the video with a “hyper-real” image, since the amount of processing 60 times per second during the shoot caused 24-25 progressive frames per second. Digital Video Digital technically superior. Today we have a new generation digital cameras with a technology that eliminates the difficulty of frequent exchanges of strips, as in previous digital cameras. There are some important factors that can help you choose a digital camera. tape or disk: Decide whether you want a camera that records on tapes or disks. Digital video can be recorded on tape and disk format. Other media are also card as a webcam, cameras, DVD camcorders and hard drive are used. Pixel: The images are clear with realistic colors, as the number of megapixels is more. Instead of the large number of pixels that can detect a camera that should be considered the number of effective pixels. are the numbers of effective pixels CCD camera used during the recording will be. CCD: CCD Chip-covered pixel information similar to the way the film captures the light for a camera. obtain images with brighter colors better taken with large CCD sensor with more light image. Low Light Performance: Since most digital cameras are used in home video, it’s important to take a camera to find the best performance in low light. Some models offer a night vision function to take pictures in dark environments. Zoom: There are two types of digital cameras with digital zoom and optical. razor-sharp picture and get the optical zoom is important. Some digital video cameras, is equipped with a digital zoom, namely the existing image is enlarged, which is linked to fewer clear images with fewer pixels. Image stability: Another complaint with the image quality, shaky images, apart from the images LowLight. Networking: Most digital cameras are a number of sockets on the rear panel for connecting the digital camera to a VCR or DVD recorder. Just look at the available connections on your VCR or DVD, or compatible computer. LCD monitors: more pixels on the LCD screen, the better the image quality. Manual settings include: To the point and images, such as automatic settings from the menu on the left. to adjust the image to the desired conditions, manual controls for focus, aperture, shutter speed and white balance for the quality of images. Where to buy: Make sure the camera to buy from a reliable source.
