Hello there, 
I have a simple one, 
I have run the exmaple project on camera dcmipp continous mode and snapshot mode for the stm32n6570 development kit, how, the image feed on the screen is blurred on the first run with out any edits, 
I have tried to play with the downsizing that is configured in the project in vain, hoping to get a clearer image.

these are the default settings that I that come with the example 

DonwsizeConf.HRatio = 25656;

DonwsizeConf.VRatio = 33161;

DonwsizeConf.HSize = 800;

DonwsizeConf.VSize = 480;

DonwsizeConf.HDivFactor = 316;

DonwsizeConf.VDivFactor = 253;



if(HAL_DCMIPP_PIPE_SetDownsizeConfig(&hdcmipp, DCMIPP_PIPE1, &DonwsizeConf) != HAL_OK)

{

Error_Handler();

}

if(HAL_DCMIPP_PIPE_EnableDownsize(&hdcmipp, DCMIPP_PIPE1) != HAL_OK)

{

Error_Handler();

}

I also failed to find documentaion that takes about these parameters and what their effect is leave alone
the getting started with dcmippp documentation, it helps not.

Can someone please tell me why the image is blurry or is it the case of the exmaple that it is supposed to be.

I am still a nonvice to STM and all things conserning its dev board.

Hello @Kamurasi-Jordan-Arthur and welcome to the community;

 

Are you using STM32N6570-DK board? If so, what is the revision of the board?

For more information about the Downsize information, I recommend you to look at RM0486 Rev 2 Section 39.7.4 Downsize.

 

I hope this help you.

Thank you.

Thank you @KDJEM.1  for your reply, 
That surely would have helped alot at the time with the down size setting.

I find that the IMX335 camera module has a manual focus for adjustment, hence outof the box
The focal lenth has to be set by manually rotating the "lens holder" in order to achive a clear image.
