IONOS IP - Gamma
IONOS IP CORE 
Gamma Correction

 

 

 
Overview
 
Pixels are illuminated in a linear way. To provide pixel data to common video systems a conversion to a non-linear value encoding may be needed.
 
 
Goal
 
Conversion of a RGB-input signal from linear to non-linear value or otherwise under usage of arbitrary gamma correction factors.
 
 
IP-Features
 
  • Selectable bitwidth (1..32Bit) for each color channel data, HDR ready
  • Image resolution more than 10MP possible, HD ready (720p/1080p)
  • Selectable output datawidth (for RGB)
  • Automatic interpolation between look up table entries Implied sync signal synchronization
  • Reset-input for global/local reset
  • Separate correction for each single color channel
  • Dynamic Setup via Wishbone-interface
  • Flexible modification of correction parameters
  • Ready-to-use platform library and structure header files for Mico32 Gamma Compression or expansion possible to switch during processing
