Multi (2) Exposures High Dynamic Range (HDR) IP

NIX is multi-exposure high dynamic range IP, commonly known as HDR, which is based on 2 exposures blending (long and short exposures).

With NIX IP, saturated (too much light) and under-saturated (too little light) regions of the image are corrected to enhance the visibility.

NIX is provided with advanced tone mapping to maximize the dynamic range and to generate natural-like images.

NIX has target range of 96 dB with line-interleave support.

Features

2-exposure blending HDR
Input formats

Max. 20 bit Bayer

Output formats

10 bit Bayer

Performance

1920x1080 at 60fps - 124MHz

Interface

ARM® AMBA 4 AXI Interface compliant

Benefits

Synthesize long exposure image and short image into a single image for the purpose of maximizing the dynamic range. The resulted image will provide high visible and natural image.
NIX provides tone mapping to maximize dynamic range and to generate natural image. Also, contrast correction is integrated to remove offset resulted from long/short image fusion.
Nix has target range of 120 dB with line-interleave support
