Abstract

In an effort to realize a compact HDTV camera with high performance, we have developed a prototype equipped with four 2/3-inch CCDs. A smaller image format is preferable for downsizing TV cameras. However, this causes shrinkage of the unit pixel size and inevitably makes it more difficult to produce an image-pickup device with required HDTV qualities, especially sensitivity, and dynamic range. We have overcome this problem by using CCD imagers with high performance but with a relatively small number of pixels and by increasing the number of CCD chips used in a camera to secure the necessary spatial sampling points for HDTV. In the newly developed color-separating system of the camera, two of the four CCDs are assigned for the green (G) light component and one each for red (R) and blue (B). We succeeded in improving the resolution by introducing spatial pixel offset imaging. This new method has two major advantages: it prevents resolution degradation caused by chromatic aberration and improves the resolution of colored signals over a wide range.
