Image sensor noise can be compared across formats for a given fixed photon flux per pixel area (the P in the formulas); this analysis is useful for a fixed number of pixels with pixel area proportional to sensor area, and fixed absolute aperture diameter for a fixed imaging situation in terms of depth of field, diffraction limit at the subject ...
A micrograph of the corner of the photosensor array of a webcam digital camera Image sensor (upper left) on the motherboard of a Nikon Coolpix L2 6 MP. 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.
It was the first CMOS sensor with intra-pixel charge transfer. [2] In 1999, Hyundai Electronics announced the commercial production of a 800x600 color CMOS image sensor based on 4T pixel with a high performance pinned photodiode with integrated ADCs and fabricated in a baseline 0.5um DRAM process.
Resolution & pixel size listed below is after re-mosaic signal processing. [5] Nonacell is similar to Tetracell, but with 3x3 pixel groups and a 6×6 pattern with 9 red, 18 green and 9 blue subpixels. ChameleonCell is similar to Tetracell and Nonacell, but with 4x4 pixel groups and a 8x8 pattern with 16 red, 32 green and 16 blue subpixels.
Nikon uses DX format sensors with slightly different active areas, which is the area where the image is captured, although all of them are classified as APS-C. Image sensors always have additional pixels around the active pixels, called dummy pixels (unmasked, working pixels) and optical black pixels (pixels which are covered by a mask used as a black-level reference).
Drawing showing the relative sizes of sensors used in most current digital cameras. Advanced Photo System type-C (APS-C) is an image sensor format approximately equivalent in size to the Advanced Photo System film negative in its C ("Classic") format, of 25.1×16.7 mm, an aspect ratio of 3:2 and Ø 30.15 mm field diameter.
(* 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
