The Gamma Correction LogiCORE™ IP is an optimized hardware block for manipulating image data to match the response of display devices.

Gamma correction, also known as gamma compression or encoding, is used to encode linear luminance or RGB values to match the non-linear characteristics of display devices. The Xilinx Gamma Correction LogiCORE is implemented using a Look-Up Table (LUT) structure that can be applied to each color channel independently, or a single gamma correction curve can be applied to all three color channels simultaneously.

Key Features

• Scalable data width (8,10, 12 bits)
• Single or three color channel LUT structure
• Optional interpolated output values
