Abstract
An apparatus and method for adjusting reference transfer functions used during a certification process. In various implementations, a display testing system includes multiple display devices under test and a measurement device. An optics capturing device sends information to the measurement device based on light information received from a display device under test. For display devices that regulate power consumption based on average picture level (APL) of the test image, the measurement device generates a new reference electro-optical transfer function (EOTF) based at least upon the varying peak luminance values based on changing APLs. For display devices that do not provide a minimum luminance of 0 nits at Perceptual Quantizer (PQ) code 0 of the ideal PQ EOTF, the measurement device generates a new reference EOTF based at least in part on using electrical-electrical transfer function (EETF) equations.
