A Camera System Using Three 33-megapixel CMOS Image Sensors for UHDTV2

Abstract

This paper describe the world's first camera system that can capture images complying with the highest level image format specified in SMPTE 2036-1—(i.e., ultra-high definition television 2 [UHDTV2; 7680 × 4320/59.94 p, red, green, and blue (RGB) 4:4:4]). For this camera system, we developed a 33-megapixel complementary metal oxide semiconductor (CMOS) image sensor, an ultra-high-resolution lens, and a signal-processing function for correcting lens chromatic aberration in realtime. As a result, the limiting resolution of captured images was achieved over 4000 TV lines. Moreover, wavelength division (WDM) optical interface with nine 10-Gbit/s-serial digital interface (10G-SDI) modules was developed. Using this technology, the camera head and camera-control unit can be connected by a SMPTE 311 camera cable. In addition, the camera system's configuration and performance are also described.
