Abstract
An HDTV 2/3-inch CCD hand-held camera has been developed to meet the demand for a small, light, maintenance-free HDTV camera. This paper describes the design concept of 2/3-inch CCDs and pickup systems, taking into account present LSI technology and HDTV camera performance requirements.
One limitation is that downsizing CCDs from the 1-inch to the 2/3-inch optical format inevitably reduces the area of each pixel, resulting in insufficient dynamic range and sensitivity. To maximize the 2/3-inch CCD overall characteristics, we used 1.3 million instead of 2 million pixels.
To attain sufficient resolution with a reduced number of CCD pixels, we compensate for resolution deterioration by using the dual-green pickup method. This method provides sufficient resolution for an HDTV camera with reduced aliasing.
This camera has successfully achieved a horizontal resolution of 1100 TVL and exhibits well-balanced performance.
