Altera Develops Single-Chip Solution for HD WDR Surveillance Cameras

PR Newswire: Altera continues to develop its FPGA-based WDR camera platform and now presents a complete reference design for surveillance cameras on a single FPGA. The design uses Altera's low-cost Cyclone III or Cyclone IV FPGAs and IP from Eyelytics and Apical supporting AltaSens' 1080p60 A3372E3-4T and Aptina's 720p60 MT9M033 WDR sensors.

Traditional ISPs and ASSPs don't have the processing power required to accept the large bandwidth of data from 1080p and 720p WDR CMOS sensors (for instance, a full HD raster is 2200x1125 pixels x 16+ bits per pixel x 60fps, resulting in >2Gbps bandwidth).

Altera's HD surveillance IP camera reference design functions include:

  • Hot pixel removal and WDR sensor demosaic functions
  • A complete Image Signal Processor (ISP): including color pipeline, auto white balance and auto exposure (including exposure mixing for WDR)
  • Apical's spatial dynamic range-compression (local tone mapping) algorithm, known as "iridix"
  • Apical's 2D noise-reduction algorithm, known as "sinter"
  • Eyelytics' H.264 video encoder, capable of 720p/30fps encoding or 1080p/15fps encoding in main profile
  • Altera's Triple-Speed Ethernet MAC IP and Nios® II embedded processor cores

Altera also presents a nice video on its new WDR platform:

    This is cool for monochrome sensors; it doesn't solve the problem of color reproduction when using non linear response in WDM.
    You can see the color of the leaves oustide the window, before and after the WDM is turned on.
    Also the sky turns to gray. I think the desing is good to handle the 1080p 60fps, but no need for the WDM.

    Sorry, even for monochrone sensor, it's not that cool ! Have you used such kind of sensor ??
