The IMX989 is Sony's first 1-inch camera sensor designed for smartphones. It was used in Sharp Aquos R7 and Xiaomi 12S Ultra smartphones.[3][4]
Versions
Exmor R
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]
Exmor RS was announced on 20 August 2012 and is the world's first stacked CMOS image sensor.[8][non-primary source needed] Subsequently, Sony announced the first 3-layer stacked CMOS sensor, which added DRAM cell array in the middle.[9]
From the Exmor RS line, IMX582 or IMX586 sensors are widely implemented as 48 megapixel smartphone cameras (e.g. Samsung Galaxy S20), with the sensors having almost identical specifications, but for the IMX586 supporting faster frame rates at 4K. In early 2020, the IMX586 was followed by the IMX686, enlarging the format to 1/1.72" (increasing resolution to 64 megapixels), but keeping the same pixel size.[10] Pixel binning is used to reduce the high sensor resolution to standard photographic resolutions such as 4K, overcoming some of the traditional limitations of Bayer filtering.
STARVIS
STARVIS is a series of sensors with the Exmor RS family.[citation needed] It features high pixel sensitivity, making it suitable for low light applications. Industrial versions are finding applications in ambient-light surveillance systems. Commercial versions are finding applications in prosumer webcams with 4K HDR support, based on single exposure.
STARVIS 2
From the second-generation STARVIS line (STARVIS 2), the IMX585 was announced on 29 June 2021,[11] featuring a large image sensor format of 1/1.2", making it suitable for low light photography. Sony designed the STARVIS 2 sensor family for AI face recognition in surveillance applications with difficult lighting conditions.[12][promotional source?] The sensor's high dynamic range assists with this task. It became available in a Razer Inc. prosumer webcam in January 2023.[13] Larger sensor form factors decrease depth of field, which is often desired for teleconferencing webcams. Sony claims near DSLR quality for some applications.[13]
Exmor T
Sony introduced the Exmor T with the Xperia 1 V smartphone on 10 May 2023.[14]
LYTIA
On 7 November 2022, Sony announced their LYTIA brand of CMOS image sensors for mobile devices.[15][16][17]
