The share hold of mobile displays in the content distribution market has grown significantly over the past decade. These displays add new complication to media color management as they can be viewed across a wide range of environments over a short span of time. There is currently no consensus within the color science community on the extent to which surround adaptation to ambient chromaticity has a significant impact on the color appearance of image content on these displays. Thus, an investigation into this query has been conducted at the Dynamic Visual Adaptation Laboratory at the Rochester Institute of Technology in Rochester, NY. The study aimed to quantify the color appearance impact of these surround signals. Observers performed an asymmetric memory matching task for a set of images viewed under SMPTE standardized mastering conditions and under a series of ambient illumination conditions with varying chromaticity and luminance. The results suggested that observers adapt partially to the chromaticity of ambient illumination while viewing images on portable displays, and also that this mixed adaptation ratio varies as a function of ambient luminance and stimulus type (self-luminous solid color versus images).
