Exmor

It performs on-chip analog/digital signal conversion and two-step noise reduction in parallel on each column of the CMOS sensor.

The new sensor distinguishes itself from the previous Exmor RS sensors by an AI processor and a memory storing the AI models, included in a stacked logic layer for the real-time image analysis and instant extraction of metadata from a raw image.

[6][non-primary source needed] Sony claims that Exmor R is approximately twice as sensitive as a normal front illuminated sensor.

[citation needed] This active pixel sensor is found in several Sony mobile phones and cameras as well as Apple's iPhone 4s and 5.

[9][non-primary source needed] Subsequently, Sony announced the first 3-layer stacked CMOS sensor, which added DRAM cell array in the middle.

Commercial versions are finding applications in prosumer webcams with 4K HDR support, based on single exposure.

Sony designed the STARVIS 2 sensor family for AI face recognition in surveillance applications with difficult lighting conditions.
