Editing Digital camera (section)

=== Sensor resolution ===
The [[Image resolution|resolution]] of a digital camera is often limited by the [[image sensor]] that turns light into discrete signals. The brighter the image at a given point on the sensor, the larger the value that is read for that pixel. Depending on the physical structure of the sensor, a [[color filter array]] may be used, which requires [[demosaicing]] to recreate a [[Color image|full-color image]]. The number of pixels in the sensor determines the camera's "[[pixel count]]". In a typical sensor, the pixel count is the product of the number of rows and the number of columns. '''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 [[Photosite|photosites]], or a surface that is 50 times larger.  <ref>{{Cite book |last=Maitre |first=Henri |title=From Photon to Pixel. |date=2017 |publisher=John Wiley & Sons, Incorporated |isbn=978-1-119-40243-5 |edition=2nd |location=Newark |oclc=975225434}}</ref>
