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

摘要

We describe a world's-first camera system that can capture images complying with the highest-level image format specified in SMPTE 2036-1 - i.e. UHDTV2 (7680×4320/59.94p, R/G/B 4:4:4). For this camera system, we developed a 33-million-pixel CMOS image sensor, an ultra-high-resolution lens, and a signal-processing function for correcting lens chromatic aberration in real time. As a result, the limiting resolution of captured images was achieved over 4,000 TV lines. Moreover, WDM optical interface with nine 10G-SDI modules was developed. Using this technology, the camera head and camera-control unit can be connected by an SMPTE 311 camera cable. In addition, the camera system's configuration and performance are also described.
