Rockchip Compares its ISP with Apple

Embedded Vision publishes Rockchip article comparing its AP image processing engine with one from Apple:

"The RK1608 utilizes the CEVA-XM4 DSP core to perform frame-based processing, rather than line-based as in ISP. Because it is specifically designed for image processing, it can perform much faster than a standard AP. It includes features like multi frame de-noise, zig-zag HDR for preview and capture, HDR processing of multi-exposed image, depth map generation, super resolution and pseudo optical zoom. The vision coprocessor’s function is not dependent on the ISP, so it can be adapted to any platform.

One phone already available on the market that uses the RK1608 for enhanced photography, is the ASUS ZenFone 3 Zoom smartphone, launched earlier this year at CES 2017. If there was ever a phone that truly threatened DSLRs, this is it. This device was designed to be a camera just as much as it was designed to be a phone. The aperture, pixel size and sensor are among the largest in the industry at f/1.7, 1.4┬Ám and 1/2.55”, respectively. It uses new SuperPixel camera technology for clearer images at night or in low-light environments and offers 2.5-times greater light sensitivity than the Apple iPhone 7 Plus.


  1. typo in headline - should say Rockchip

  2. CEVA-XM4 core dates back to approx 2015, is that right?
    don't they have a newer core they've already announced?

    1. We announced CEVA-XM6 late last year and we already have several licensees.
      You are welcome to read more

  3. difficult to manage HDR scene!

  4. The bright line comes from non-HDR optical lens and not from bad HDR processing!
