目前电子耦合器件(CCD)技术已经应用到广播级摄像机里,並显示出许多超过摄像管的优点。这些优点是:体积小,重量轻,坚固耐用,功耗低,並且不会发生烧伤、慧尾和图像残留现象。CCD技术的应用,一直存在两个问题:一是当拍摄高亮度的物体时产生垂直拖影;另一个是与摄像管相比其清晰度较低。为此,研制了一种使用改进的固态图像传感器和双绿系统的摄像机。改进的固态图像传感器实际上消除了垂直拖影现象,双绿系统摄像机的清晰度达到了与摄像管相同的水平。本文还介绍了一种使用新的电子快门的摄像机,这种摄像机所达到的动态分解力可与电影摄影机的清晰度相媲美。
At present, electronic coupling device (CCD) technology has been applied to broadcast cameras, and shows many advantages over the camera tube. These advantages are: Small size, light weight, ruggedness, low power consumption, and no burn, hissing, and image sticking. There have been two problems with the application of CCD technology: one is vertical smear when shooting a high-brightness object, and the other is less sharpness than a camera tube. For this reason, a camera using an improved solid-state image sensor and a dual green system has been developed. The improved solid-state image sensor virtually eliminates vertical smear, and the dual-green system camera achieves the same level of clarity as the camera tube. This article also introduces a video camera that uses a new electronic shutter that achieves a dynamic resolution comparable to that of a movie camera.
