WDR Converter

Product Overview

WDR (Wide Dynamic Range) is a technology to retouch/correct SDR images in high-contrast scenes, without generating blackouts and whiteouts. Since the dynamic range of a standard camera is limited, it is hard to capture high-contrast scenes properly, usually resulting in overexposure or underexposure.

TMC has developed and commercialized an original IP that provides an easy to see images visually and can easily detect an object even with a general object recognition algorithm by correcting the image with such overexposure or underexposure by our own technology.

Model Number

  • TM2777A


  • Suitable for preprocessing of object recognition by AI, by improving the visual quality of images with a large difference in brightness such as backlight and night.
  • High-speed operation by optimizing the algorithm


  • Supporting RGB input / output, YCbCr444 input / output, YCbCr422 input / output.
  • Scan Mode: Progressive.

  • Video signal Input / output signals: Hsync, Vsync, DE, and 8-bit depth video data
  • Compatible with YCbCr / YUV

Application Examples

By using WDR as a pre-processing for object recognition by AI, it can be expected to improve the recognition rate in adverse environments such as dark environment.
