Tone Mapping Operator (TMO) Intel® FPGA IP

The TMO Intel FPGA IP modifies the contrast of a video stream to improve visibility in a wide variety of applications, such as medical imaging, video conferencing, daylight projection, security cameras, and machine vision. The IP is tile-based to take account of local exposure variations, improving the visibility of latent image detail to enhance and ease the overall viewing experience. The TMO IP core accepts RGB-format video input as an AXI4-Stream, statistically analyzes the image luminance (locally and globally) and dynamically adjusts image components to improve overall image contrast. These operations enhance underexposed and overexposed imagery to fully utilize the available dynamic range. The TMO IP requires an external processor, such as the Nios® II processor FPGA softcore, to allow configuration of TMO IP blocks and take measurements via the register bus.
