Abstract: High dynamic range displays based on dual panel LCD are a viable option for building a low-cost solution for providing high bit depth visualization systems. One of the factors limiting the usability of this type of displays are the computation requirements of the algorithm necessary for correct visualization using the two stacked panels. In this work we present the methodology and the results of mapping this algorithm on a CPU+GPU platform using the OpenCL 1.1 API. Visualization of a 2048×2048 image when executed on a CPU+GPU (AMD Radeon V7800) platform is performed up to 7.6 times faster then when only the CPU is used. The first results are promising and encourage the use of GPUs (or APUs) for acceleration of this kind of processing.
