摘要：This experimental 60 frames-per-sec progressive-scan HDTV camera has 1, 920 × 1, 080 pixels and three CCDs for RGB color. The horizontal CCD of the camera was driven at 148.5 MHz, and the transfer efficiency of the CCD cell was about 99.98%. A 2/3-inch 2.2-million pixel FIT (Frame Interline Transfer) CCD for an interlaced HDTV camera was used for the progressive scanning. This involved using multiple FIT drives and storing the odd numbered picture lines in the field memory and the even numbered picture lines in the vertical signal transfer CCD. The horizontal and vertical resolutions of this camera were each about 1000 TV lines (TVLs), and the vertical MTF (Modulation Transfer Function) response was about 57% on 700 TVLs and 30% on 1000 TVLs. A computer simulated conversion from a progressive to an interlaced image that used images acquired by this experimental camera reproduced an alias-suppressed interlaced image.
