In digital photography, the image sensor format is the shape and size of the image sensor. The image sensor format of a digital camera determines the angle of view of a particular lens when used with a particular sensor. Because the image sensors in many digital cameras are smaller than the 24 mm × 36 mm image area of full-frame 35 mm cameras ...
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 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 following digicams include a -inch CCD sensor, a fixed lens with a maximum aperture of f/ 2.4 or wider, and SD or CompactFlash (CF) memory card slots. However, none of them support SDHC / SDXC memory cards or AA / AAA batteries. Even larger CCD sensors were only included in interchangeable-lens cameras, such as the Canon 1D, Nikon D60, and ...
A time delay and integration or time delay integration (TDI) charge-coupled device (CCD) is an image sensor for capturing images of moving objects at low light levels. While using similar underlying CCD technology, in operation it contrasts with staring arrays and line scanned arrays. It works by synchronized mechanical and electronic scanning ...
APS-C. 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.

Photo response non-uniformity. Photo response non-uniformity, pixel response non-uniformity, or PRNU, is a form of fixed-pattern noise related to digital image sensors, as used in cameras and optical instruments. Both CCD and CMOS sensors are two-dimensional arrays of photosensitive cells, each broadly corresponding to an image pixel.
