+*
+* Previewer allows fine tuning of the input image using different
+* tuning modules in IPIPE. Some examples :- Noise filter, Defect
+* pixel correction etc. It essentially operate on Bayer Raw data
+* or YUV raw data. To do image tuning, application call,
+* PREV_QUERY_CAP, and then call PREV_SET_PARAM to set parameter
+* for a module.
+*
+*
+* Resizer allows upscaling or downscaling a image to a desired
+* resolution. There are 2 resizer modules. both operating on the
+* same input image, but can have different output resolution.
