Abstract: This paper will describe the system design of the world's first 70mm, 25 megapixel, electronic-cinematography camera with an integrated flash memory recorder. Although this camera shares many of the attributes of NHK's Ultra High Definition Television and benefits from NHK's pioneering research in the area of very high-resolution imaging, what we are about to describe is an electronic cinematography camera and recorder - not a television camera. While the unique requirements of the cinematographic process allow us to take advantage of certain processes that would not be practical in a television environment, we must also make provision for requirements that are unique to movie making. The single CMOS sensor in the new Panavision camera has the same four times HDTV horizontal resolution of 7680 photo-sites as that proposed by NHK for UHDTV. Our sensor's vertical resolution is only three times the HDTV vertical for a resolution of 3240 photo-sites and an aspect ratio of 2.37:1 rather than UHDTV's 16 × 9, 1.78:1 aspect ratio. Bucking the recent trend to take a lower resolution imager and interpolate to a higher resolution, the Panavision camera utilizes an oversampling technique to output a full bandwidth 19 megapixel RGB image from the available 25 million photo-sites. The recorded frame size is 3840 × 1620 × 3 (RGB) or 18,662,400 pixels.
