Systems, methods, and computer readable media to improve the operation of electronic display systems. Techniques for inverse tone mapping operations for selected standard dynamic range (SDR) images are described. The converted images may be presented on high dynamic range (HDR) displays so as to increase a user's viewing experience (through an expanded dynamic range) while preserving the artistic content of the displayed information. Techniques disclosed herein selectively transform SDR images to HDR images by determining if the SDR images were created from HDR images (e.g., through the fusion of multiple SDR images) and if their quality is such as to permit the conversion without introducing unwanted visual artifacts. The proposed techniques apply a sigmoidal inverse tone mapping function configured to provide a perceptual-based tone mapping. Values for the function's tuning parameters may be set based on what may be determined about the original HDR-to-SDR mapping operation.
