8K Super Hi - Vision is an ultra - high - definition image of 33 million pixels, which is 16 times the high - vision currently being broadcast.


Up to now, in order to shoot 8K Super Hi-Vision images, we needed three image sensors for RGB and a color separation prism, which seems to make it difficult to miniaturize the camera. Therefore, an image sensor capable of shooting 8K Super Hi-Vision images with one image sensor was developed. The frame frequency of the image sensor released this time is 60 Hz.


Increasing the number of pixels of the image sensor reduces the sensitivity as the area per pixel decreases. So it seems that with 133 megapixel image sensor it is possible to secure an area per pixel by using an image sensor of a larger size than the conventional one to suppress the decrease of sensitivity.


And by designing so that the diagonal of the image pickup surface is almost the same as 35 mm full size, it is designed so that a commercially available 35 mm full-size steel camera lens can be used.


In the 133 million pixel image sensor, 4 pixels of the image sensor constitute one pixel of the video signal.


At the booth, we were shooting images using this 133 million pixel image sensor.
