Abstract

We have developed an 8K "full-resolution," 60-fps, portable camera system using a 133-megapixel complementary metaloxide-semiconductor (CMOS) single-chip image sensor. The camera head weighs less than 7 kg, whereas the conventional 8K full-resolution three-chip camera weighs over 50 kg. The new camera can use both commercial 35-mm full-frame lenses and super 35-mm lenses by using lens adapters. It employs a compact 100-Gbps optical transceiver that can transmit the 8K fullresolution video signal to the camera control unit (CCU). The size of the CCU is 3U, which is comparable to CCUs used for broadcasting high definition television (HDTV) cameras. The camera supports the wide-color-gamut and high dynamic range (HDR) video formats, which were standardized in ITU-R BT. 2020 and BT. 2100, respectively. Moreover, a streaking noise correction circuit is implemented in the CCU. The 8K signal output interface from the CCU is compliant with the ITU-R BT. 2077 (U-SDI) standard. By performing an image shooting experiment, we confirmed that the limiting resolution of this camera was more than 4000 TV lines and the signal-to-noise (S/N) ratio was 57 dB at a sensitivity of F4.0/2000 lux.
