Quantum efficiency (QE) is a figure given for a photosensitive device (charge-coupled device (CCD), for example) which is the percentage of photons hitting the photo reactive surface that will produce an electron-hole pair. It is an accurate measurement of the device’s sensitivity.

Unwanted noise that is generated by the on-chip output amplifier.

Three colors wherein no mixture of any two can produce the third. For electronic imaging these are the additive primary colors red, blue and green.

The progressive scan is a format for reading an image in sequential order, line by line.

For electronic imaging the term refers to process of extracting the image, pixel by pixel from the sensor.

Refers to an area that is user-defined, typical a rectangular area on the sensor that is exposed and processed as an image.

User-defined resolution, a rectangular exposure area on the sensor.

A measure of the ability to resolve an edge on an object.

Similar to sensitivity this is a term for describing the rating of the output current from a camera sensor divided by the incident flux of light, usually expressed in signal current per watt of input radiation at a specific wavelength.
