High-speed front-end LSI chip
A new front-end LSI ( large scale integration ) chip supports the BIONZ
processing engine to significantly boost performance during the early stages of
processing. By accelerating the handling of image sensor data early on, the LSI chip
frees other BIONZ components to achieve a more subtle level of peripheral shading
compensation and advanced black level offset correction that significantly raises
image quality.

Area-specific noise reduction
This intelligent noise reduction selectively divides the image into
areas based on patterns ( such as edges, textures and evenly
colored areas like blue skies ) , then optimally processes each
area to markedly reduce noise and improve image quality—
especially when shooting in dimly lit environments. Combined
with conventional noise reduction, this new feature delivers
clear, low-noise images throughout the entire 9-stop range
( ISO 100–25600, expandable to ISO 50 ) .
