Hi everyone, I ran grayscale\_binary\_filter\_1.py example code and got this problem:

![](https://canada1.discourse-cdn.com/flex029/uploads/openmv1/original/2X/1/1bcac7b2a62c11638dbc46f93de78a3aab2a15e5.png)

But 2 weeks ago, I made my binary example code, the output was:

But, other functions was worked normally.  
I only got strange outputs.  
How can I fix this problem? Is my OpenMV CAM broken?

Thanks for all replies,  
Eric

Hi, Mr.kwagyeman. Here’s my video for example code on YouTube:

I just ran the example too, but output was very strange.

Hi, this is an issue with the M7 JPEG compression. The actual frame buffer is fine. But, when being jpeg compressed there seems to be an error.

Hello Mr.kwagyeman. Thanks for reply.  
I’m glad this problem is not a hardware problem.  
Hope problem will be fix shortly, then I can use this awesome cam to finish my thesis project.  
Best regards,  
Eric
