The common 1" outside diameter circular video camera tubes have a rectangular photo sensitive area about 16 mm on the diagonal, so a digital sensor with a 16 mm diagonal size is a 1" video tube equivalent. The name of a 1" digital sensor should more accurately be read as "one inch video camera tube equivalent" sensor.
(* The pixel number of 6,000x4,000 ist the number of "effective pixels". The sensor usually has a few extra rows of pixels on all four sides, which explains the sensor resolution of 24.3 MPixels often stated, but no information about the exact image size available.) 6,016 4,000 24,064,000 24.1 Nikon D3300 Canon M50: 6,048 4,032 24,385,536 24.4
Examples include the Sigma DP1, which uses a Foveon X3 sensor; the Leica X1; the Canon PowerShot G1 X, which uses a 1.5″ (18.7×14 mm) sensor that is slightly larger than the Four Thirds standard and is 30% of a full-frame sensor; the Nikon Coolpix A, which uses an APS-C sensor of the same size as those found in the company's DX-format DSLRs ...

The Nikon 1 J1 is a Nikon 1 series high-speed mirrorless interchangeable-lens camera with 1" sensor size launched by Nikon on September 21, 2011. It is a new model that focuses on high-performance, portability and versatility. Nikon lists the estimated selling price of the Nikon 1 J1 One-Lens Kit in the United States at $649.95.
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. On full-frame sensors (i.e., 24 mm 36 mm), some cameras propose images with 20–25 million pixels that were captured by 7.5–m photosites , or a surface that is 50 times larger.
Its highlight features are its 1-inch (13.2 x 8.8 mm) backside-illuminated Exmor R CMOS sensor, with 20.2 megapixels, ƒ/1.8 to ƒ/4.9 Carl ZEISS® Vario-Sonnar T* lens and a 3.6x (28–100 mm) optical zoom, all taken straight from the Sony RX100 II premium compact camera.
Optical format is a hypothetical measurement approximately 50% larger than the true diagonal size of a solid-state photo sensor.The use of the optical format means that a lens used with a particular size sensor will have approximately the same angle of view as if it were to be used with an equivalent-sized video camera tube (an "old-fashioned" TV camera).
