The active area may be smaller than the image sensor, and active area can differ in different modes of operation of the same camera. Active area size depends on the aspect ratio of the sensor and aspect ratio of the output image of the camera. The active area size can depend on number of pixels in given mode of the camera.
In a CCD image sensor, pixels are represented by p-doped metal–oxide–semiconductor (MOS) capacitors.These MOS capacitors, the basic building blocks of a CCD, [1] are biased above the threshold for inversion when image acquisition begins, allowing the conversion of incoming photons into electron charges at the semiconductor-oxide interface; the CCD is then used to read out these charges.
The plate scale of the James Webb Space Telescope component Fine Guidance Sensor and Near Infrared Imager and Slitless Spectrograph is about 0.066 arcsec/pixel. [2] It uses a 2040 x 2040 pixel array with a pixel size of 18 microns per side with a field of view of 2.2' x 2.2' [3]

Super CCD is a proprietary charge-coupled device image sensor design that was developed by Fujifilm starting in 1999 [1] and marketed with its digital cameras, starting with the FinePix 4700 and S1 Pro. Super CCD cameras were sold until 2010.
(* 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
Some liken CCD to slide film (also known as positive film) and CMOS to negative film. [36] While there were larger CCD sensors made for interchangeable-lens cameras, such as the Leica M9, CCD sensors in fixed-lens cameras maxed out at 2/3″ (1/1.5″). Premium compact cameras of the time contained sensors around 1/1.7″ in size, whereas entry ...
