Image Processing Speedup on ARM GPU

ARM Blog published a guest post by Japan-based Synthesis Corporation optimizing its image processing IP for ARM Mali-T600 GPU. The two examples are super-resolution and HDR, both showing a significant speedup:

Synthesis also demos its real-time HDR video capabilities in this Youtube video:


  1. What about power consumption? That's the big problem here.

  2. This is a simple adaptive gamma correction, not really HDR. The computation power may not that high. Of course, if they use local tone mapping effectively it can be heavy in computation. Anyway the term HDR here is misleading!

  3. I agree. This is change an modified tone curve. I don't see any increase in dynamic range. There's no additional details in bright objects or more detail in black areas.
