Hi,

Thanks for your post.

Unfortunately, the THS8200 does not have a scaler. But if you still need to resize your image, you can check the image resizing method within a VB.NET image process project below:

In general we never use such THS8200 to process image, there are many free trial image resizing and other image editing tools which you could try as below:

Also, there is a "calccoef" utility associated with the "Understanding the Davinci Resizer" app note (SPRAAI7B) to generate coefficients and other resizer parameter structure values as below:

Alternativey, you could also try to walkthrough the below E2E thread to interface a DaVinci SoC DM6446 to a THS8200:

To use resizer on DM6446, please refer the below E2E thread and hope it helps:
