Even home video cameras that have three chips are of poorer quality than professional cameras. The chips they use have fewer pixels and are not of the same quality as those used in professional cameras. 40 Luminance information E N C O D E R R G B 1 Encoded composite video signal Chrominance information Stripe filter CCD Chip Composite Encoding 2 1. Encoding. 2. Color home video camera. 41 CRTs convert color signals to video images. Color CRTs Just as the color camera works in a manner similar to the black and white camera, the color CRT works in a manner similar to the black and white CRT.

17 The electron beam needs to get back to its starting point. Blanking The intensity of the electron beam during the scanning process is not constant. It varies in a logical, consistent pattern corresponding with the brightness of the picture as the beam moves across and up and down the CRT’s face. If the electron beam were at full power when it returned to the beginning of a new line or field, it would illuminate phosphors on the CRT face and interfere with the information previously laid down.

Components of composite video. 51 The picture and sync must be combined. Analog Sync Generator Signals (2) Combining Sync with Video Take a moment and think about how the video system has been described here. The CCDs in the cameras are converting the light images into electrical signals, but the drive, blanking, and sync pulses that tell those CCDs to scan a line, turn down, retrace, turn back up, scan another line, start a new field, and so on are coming from outside the camera. Yet coming out of the camera, the video and sync information are combined.
