The ISC video pipeline integrates the following submodules:

  • DPC: Defective pixel correction, also including a Green Disparity Correction (GDC), Black Level Correction (BLC), Edge Adaptive Level (EAL)
  • PFE: Parallel Front End to sample the camera sensor input stream
  • WB: Programmable white balance in the Bayer domain
  • CFA: Color filter array interpolation module
  • CC: Programmable color correction
  • GAM: Gamma correction
  • VHXS: Vertical and horizontal scaling engine
  • CSC: Programmable color space conversion
  • CBHS: Performs contrast, brightness, hue and saturation control
  • SUB422: Performs YCbCr444 to YCbCr422 chrominance horizontal subsampling
  • SUB420: Performs YCbCr422 to YCbCr420 chrominance vertical subsampling
  • RLP: Performs rounding, range limiting and packing of the incoming data.
