New ContributorTone Mapping Operator IP Malfunctioning
Hello, I am currently evaluating the Tone Mapping Operator IP from the Video and Vision Processing Suite for integration into our video camera product. The issue is that when attempting to enable...
Hi @dscully David,
Does this IP have undocumented restrictions on input resolution?
>> Yes, there is restrictions on the input resolution.
For the input width, it needs to be multiple of the pixels in parallels (PIP) and the number of internal tiles (it is fixed as 4)- So, if PIP = 4 and Number of tiles = 4, then the width needs to be multiple of 4x4 = 16
- For the given two widths you could see that condition is not met, 1944/16 = 121.5 and 3268/16=204.25
- I suggest your to try: 1952 for the first case,
- and 3280 for the second case, then if need be, you could use a clipper to put the width back to your desired width.
- For the input height, it needs to be multiple of the number of internal tiles (it is fixed as 4)
- In this case, your current values are both fine.

Regular ContributorHi,
May I know what device that you are targeting on this project ?
There is some idea out of my mind where we can try to narrow down the issue further bit
- before TMO insert a gain on R only (e.g., scale R up). If ROI stays black but the rest of the frame changes, the input is RGB; if nothing changes, the source into TMO may be packed/zeroes.
- set ROI to almost full frame and enable it. If black goes away → ROI alignment/width issue.
- Do you try other lower/higher resolution rather than 2k ? is this issue happen in other resolution ?
