| adjustment, running the computation on the device\'s GPU or other compute hardware as deemed appropriate by the system. |

| [RenderScript][1] is a framework for running computationally intensive tasks at high performance on Android. RenderScript is |
| primarily oriented for use with data-parallel computation, although serial computationally intensive workloads can |
| benefit as well. |
| |
| The RenderScript runtime will parallelize work across all processors available on a device, such as multi-core CPUs, |
| GPUs, or DSPs, allowing you to focus on expressing algorithms rather than scheduling work or load balancing. |
| RenderScript is especially useful for applications performing image processing, computational photography, or computer |
| vision. |
| |
| This sample demonstrates the fundamentals of writing a RenderScript compute kernel, and using it to perform basic image |
| manipulation. In this case, each pixel is transformed based on a liner interpolation between its original |
| RGB value and it's luminance (black-and-white) value, weighted based on the user's specified saturation target. |
