SH7766

Features

The SH7766 is an image recognition SoC that improves on the capabilities of the SH77650 image recognition SoC with proven results that is currently in mass production. It also has an enhanced view function and a higher performance image recognition engine.
New functions include a viewpoint conversion engine, dynamic range control, a hardware engine for view function, and the IMP-X2 next-generation image recognition engine, which retains library compatibility with the existing image processing engine (IMP) while boosting processing performance over fourfold.
