Fujifilm X-Trans sensor

Typical Bayer sensor arrays have RGB photosites in a repeated 2 by 2 pattern. When it overlaps with a regular pattern that is being captured, a new interference pattern can occur that does not exist in real life. In contrast, X-Trans sensors have a more irregular pattern of RGB photosites than conventional Bayer array sensors,{{Cite web|url=http://www.fujifilmusa.com/products/digital_cameras/x/fujifilm_x_pro1/features/|title=Fujifilm X-Pro1 {{!}} Features - APS-C 16M "X-Trans CMOS" {{!}} Fujifilm USA|website=www.fujifilmusa.com|access-date=2017-01-12|archive-date=2020-05-26|archive-url=https://web.archive.org/web/20200526023309/https://www.fujifilmusa.com/products/digital_cameras/x/fujifilm_x_pro1/features/|url-status=dead}} reducing the likelihood of interference and removing a need for a low-pass filter that lowers image resolution.{{Cite patent|country=US|number=8531563|title=Color imaging apparatus|gdate=2013-09-10|invent1=Tanaka|inventor1-first=Seiji|assign1=Fujifilm}}

Conventional Bayer sensors can also produce false colour as they do not have R and B photosites in some horizontal and vertical lines, Fujifilm claims that X-Trans sensors on the other hand have an improved colour reproduction due to all horizontal and vertical lines containing at least one R, G and B pixel out of every 6.{{Cite web|url=http://www.fujifilmusa.com/press/news/display_news?newsID=880240|title=Fujifilm introduces the revolutionary x-pro1 interchangeable lens digital camera system {{!}} Press Center {{!}} Fujifilm USA|website=www.fujifilmusa.com|access-date=2017-01-12|archive-date=2020-03-17|archive-url=https://web.archive.org/web/20200317041159/https://www.fujifilmusa.com/press/news/display_news?newsID=880240|url-status=dead}}

Fuji claims that APS-C sized X-Trans sensors, while being physically smaller, have a greater perceived resolution than the number of pixels on the sensor and are said to be on par with some full frame sensors.

While the first three generations of X-Trans sensors are front-illuminated, the fourth generation uses the principle of backside illumination. This improves noise levels and image quality.{{cite web |title=Feature {{!}} The 4th Generation |url=https://fujifilm-x.com/en-us/products/cameras/x-t30/feature-the-4th-generation/ |website=fujifilm-x.com |access-date=2022-02-23}}{{cite web |last1=Etchells |first1=Dave |title=What’s the story with Fujifilm’s X-Trans sensor tech?

Under certain conditions, cameras equipped with X-Trans II and III sensors can exhibit purple flare/grid artifacts in backlit photos.{{Cite web|url=https://petapixel.com/2017/02/23/fuji-cameras-produce-strange-purple-flaregrid-artifact/|title=Why and How Fuji Cameras Produce a Strange Purple Flare/Grid Artifact|date=2017-02-23|website=PetaPixel|access-date=2017-02-26}} This occurs due to the particular arrangement of the phase detection and masking layers on the sensor. The appearance of the effect can vary with the demosaicing algorithms in use.

In an interview with DPreview during the CP+ 2017 show in Yokohama, Japan Fujifilm confirmed that an X-Trans sensor array is to be used for its next generation of APS-C sized sensors,{{Cite news|url=https://www.dpreview.com/interviews/6648162116/cp-2017-fujifilm-interview-we-hope-that-the-gfx-will-change-how-people-view-medium-format|title=CP+ 2017 - Fujifilm Interview: 'We hope that the GFX will change how people view medium format'|newspaper=dpreview.com|access-date=2017-02-25}} whilst larger medium format sensors will continue using a conventional Bayer array because of the increased processing requirements of X-Trans filter arrangement.
