日本电气公司已开发采用有效象素数约200万(水平1920×垂直1035)CCD型固体摄象器件的三板式彩色摄象机。标准摄象条件(2000lx,F2.8,色温3200K)的信噪比为54dB。采用相关双重取样电路,以降低噪声。饱和被摄体亮度为8000lx。最小被摄体亮度为250lx,其信噪比为36dB。斑点范围为0.1％～1％(1/10v测量),现在正在研究控制斑点的方法,预计1990年实用化。另外,200万个象素数的CCD东芝也在制作。
NEC has developed a three-panel color camera using a CCD solid-state image pickup device with an effective pixel count of about 2 million (horizontal 1920 × vertical 1035). The standard imaging conditions (2000lx, F2.8, color temperature 3200K) signal to noise ratio of 54dB. Use the relevant double sampling circuit to reduce noise. Saturated subject brightness 8000lx. The smallest subject brightness of 250lx, the signal to noise ratio of 36dB. Spots range from 0.1% to 1% (1 / 10v measurements), and methods to control speckles are now under study and are expected to become practical in 1990. In addition, 2 million pixels CCD Toshiba is also making.
