Tone-mapping is essential for photorealistic interactive applications, such as games or walkthroughs, as it allows for physically-based simulations of light to be rendered in a perceptually accurate manner. However, most currently existing tone-mapping operators fail to integrate well into real-time applications; their designs do not take temporal coherency into account. We demonstrate that it is possible to improve the temporal coherence of many tone-mapping operators using a generalised time-dependant framework designed for temporally varying HDR content. The framework also accounts for...
