His contributions include the first digital-pixel CMOS image sensor in 1994; the first scientific linear CMOS image sensor with single-electron RMS read noise in 2003; the first multi-megapixel scientific area CMOS image sensor with simultaneous high dynamic range (86 dB), fast readout (100 frames/second) and ultra-low read noise (1.2e- RMS ...
The first digital camera to use a Foveon X3 sensor was the Sigma SD9, a digital SLR launched in 2002. [5] It used a 20.7 × 13.8 mm, 2268 x 1512 × 3 (3.54 × 3 MP) iteration of the sensor and was built on a Sigma-designed body using the Sigma SA mount.
A further development is the stacked CMOS sensor, [3] which layers the circuitry and image signal processor (ISP) behind the pixels, allowing the active pixel to occupy even more area, further increasing the chance of light capture. Sony, which announced the first stacked sensor in January 2012, claims a 30% increase in light captured. [20]

The two main types of digital image sensors are the charge-coupled device (CCD) and the active-pixel sensor (CMOS sensor), fabricated in complementary MOS (CMOS) or N-type MOS (NMOS or Live MOS) technologies.
The number of pixels in the sensor determines the camera's "pixel count". In a typical sensor, the pixel count is the product of the number of rows and the number of columns. Pixels are square and is often equal to 1, for example, a 1,000 by 1,000-pixel sensor would have 1,000,000 pixels, or 1 megapixel.
This is a list of smartphones with a primary camera that uses a 1.0-type (“1-inch”) image sensor or larger. However, as of February 2024, there are no smartphones that use a sensor larger than 1.0-type. The first camera phone to feature a 1.0-type sensor was the Panasonic Lumix CM1 in 2014. Seven years passed before another phone featured ...
The first commercially available sensors of Photobit were the PB-159 in 1998 and the PB-100 in 1999. [9] Micron showcased a 1.75-μm CMOS pixel sensor in 2005 and launched it in 2007. [10] Micron also developed and built a prototype of a 1.4-μm CMOS pixel sensor by 2007. [11]
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.
