Exmor
Exmor is the name of a technology Sony implemented on some of their CMOS image sensors. It performs on-chip analog/digital signal conversion and two-step noise reduction in parallel on each column of the CMOS sensor.
Exmor RS is the world's first stacked CMOS image sensor and was announced by Sony on 20 August 2012.[1][non-primary source needed] Subsequently, Sony announced the first 3-layer stacked CMOS sensor, which added a DRAM cell array in the middle.[2]
History
In October 2015, Sony Semiconductor Solutions was established as a wholly owned group company to reinforce the CMOS image sensor business and integrate the semiconductor-related business operations of Sony Group. Following the incorporation, all the Exmor sensors are designed and manufactured by the company.[3][non-primary source needed]
On May 14, 2020, the Intelligent Vision Sensor was announced with an introduction that reads: "the first image sensor in the world to be equipped with AI processing functionality". 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. In the release, only model numbers were identified and it was not confirmed whether the sensor bears a different name.[4]
Versions
Exmor R is a back-illuminated version of Sony's CMOS image sensor.[5] Exmor R was announced by Sony on 11 June 2008 and was the world's first mass-produced implementation of the back-illuminated sensor technology.[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.[7][8] Originally, Exmor R was limited to smaller sensors for camcorders, compact cameras and mobile phones, but the Sony ILCE-7RM2 full-frame camera introduced on the 10 June 2015 features an Exmor R sensor as well.
