A Three-CCD HDTV Color Camera
The development of an HDTV color camera employing three 2-million-pixel charge-coupled device (CCD) image sensors is described. One unique characteristic of this camera is its high sensitivity, achieved by imaging devices overlaid with amorphous silicon. The horizontal-CCD (H-CCD) registers are driven by a switching resonance method, which consumes only one-fourth the power required by the conventional voltage-buffer driving method. Noise suppression for I/f amplifier noise, which decreases inversely proportional to the frequency, and floating diffusion reset noise in the CCD image sensors are also described.
