Screen Test Pattern Android Application:by François SIMOND aka supercurioThis app display simple colors on your Android device screen.Those colors are then measured by a colorimeter or spectrophotometerin order to build graphs or color profiles.I recommend using free software Color HCFR: http://www.homecinema-fr.com/colorimetre/but I guess alternative solutions like Calman or ChromaPure are fine.Non-fullscreen pattern is intentional to help with measurement accuracy on displays with content-adaptive backlight/brightness control or brightness consistency issues when displaying large bright zones.(This aspect can be improved)Requirements:- A computer- A colorimeter or spectrophotometerFeatures supported:- Grayscale: 4-128- Near Black: 4-10- Near White: 4-10- Saturations: 4-16Application also has its own brightness level controlSource code:https://github.com/project-voodoo/screen-test-patterns-appSee COPYING for license stuff.
