Bionz is the trademark of an Image Processing System developed by Sony.
It is currently in many of Sony's digital cameras. Image processing in camera converts the raw image data from a CCD or CMOS image sensor into the format that is stored on the memory card.[1] This processing is one of the bottlenecks in digital camera speed, so manufacturers put much effort into making, and marketing, the fastest processors for this step that they can. Some of the models that use the Bionz image processors are DSC W150,DSC W170,W210,W350, α 700, α 900, etc.
