Ambient Light User Assessment:
Centricity Universal Viewer Zero Footprint client ambient light user assessment should be performed to ensure optimal viewing conditions. This application should not be used in outdoor lighting or other high ambient light conditions. The user should set the device brightness to the maximum value and disable any automatic brightness features on the device before use. Ensure the recommended brightness settings are in place before each use since other applications can change the screen brightness setting.
The Ambient Light User Assessment will display two standard test patterns. These patterns were developed by The American Association of Physics in Medicine (AAPM) Task Group 18, whose purpose is to create a document that provides guidance to practicing medical physicists and engineers for in-field performance evaluation of electronic display devices intended for medical use. The user should be able to discern the following information from each pattern under ideal lighting conditions.
TG18-CT : This pattern is intended to support visual inspection of the luminance response of a display device. It should be evaluated for visibility of the central half-moon targets and the four low-contrast objects at the corners of each of the 16 different luminance regions.
TG18-MP : This pattern is intended to support visual inspection of the bit-depth resolution of a display device. It should be evaluated to ascertain the horizontal contouring bands, their relative locations, and grayscale reversals.
In order to assess appropriate ambient lighting, the user should review the suggested patterns and determine whether the ability to discern the above information is comparable to ideal lighting conditions. If the user is unable to discern the above information, they will be instructed to find a more appropriate lighting environment before using the device.
