Abstract: We developed an 8K camera recorder that uses a complementary metal oxide semiconductor (CMOS) image sensor with an organic thin-film instead of photodiodes for the opto-electrical conversion element. The advent of 8K Super Hi-Vision broadcasts and an increase in the production of 8K programs across a variety of genres necessitates development of a sensor with a good signal-to-noise ratio (SNR) and high dynamic range (HDR) in order to capture the full range of HDR video. To ensure successful use of this sensor, we studied the level diagrams (e.g., balancing of sensitivity, SNR and dynamic range) that would best fit the sensor's characteristics and use all of its strengths, then proceeded accordingly. For current 8K location shooting, a workflow is needed to record raw data and post-process them into a practical video format. To implement a more efficient workflow, we chose to use HQX encoding while adding features that make it possible to store video data in a compressed form and simultaneously generate HDTV proxy data. The workflow we envisioned uses proxy data for offline editing and relinks them using online editing equipment.
