What They Say
Advanced Television reported that NHK has developed an 8K camera that can capture and record at 240 fps making it suitable for slow motion sports coverage. BS4K and BS8K broadcast at 60 fps in Japan.
To achieve both low noise and high speed, NHK STRL implemented two signal lines for each pixel column to transfer signal from the pixel to the gain amplifier, and used both alternately for conversion.
TVBEurope reported that:
As A/D conversion accounts for a large share of power consumption, NHK developed A/D conversion circuits that divide the conversion into three steps: with coarse, medium, and precise accuracy, optimising the circuits for each step, and processing in parallel.
The circuit is capable of operating at high speed, performing over a million conversions per second to handle high-speed imaging, while maintaining power consumption low enough for continuous operation, said the team at SRTL.
What We Think
As I’ve said a number of times, my view is that 60fps may not be good enough for a compelling experience with 8K for sport. (BR)
