一、最新高清晰度、高灵敏度CCD 1.1/2英寸CCD是今后摄像机发展的主流固体摄像器件CCD的作用是将通过镜头的被摄体光学像变换成电视信号。这种CCD,根据光学成像面积的大小,称为2/3英寸或1/2英寸CCD。最后,随着半导体技术的进步,摄录机小型化的发展趋势是,逐渐淘汰2/3英寸CCD,代之以高性能的1/2英寸小型CCD。这种1/2英寸CCD,在仅4.8×6.4(mm)的硅基片面积中,以与D-RAM存储器类似的半导体技术,整齐排列着9×1(μm)大小的像素约40万
First, the latest high-definition, high sensitivity CCD 1.1 / 2 inch CCD is the future development of the mainstream of the camera solid-state imaging device CCD role is to be through the lens of the subject optical image into a television signal. This CCD, according to the size of the optical imaging area, known as 2/3 inch or 1/2 inch CCD. Finally, with advances in semiconductor technology, the trend towards miniaturization of camcorders has been to phase out 2/3-inch CCDs and replace them with high-performance 1/2-inch compact CCDs. This 1/2-inch CCD, in a mere 4.8 × 6.4 (mm) of silicon substrate area, is similar to the D-RAM memory semiconductor technology, neatly arranged with 9 × 1 (μm) size pixels about 400000
