JPEG Image compression

[hitesh_gambhava]

Hi,

In my application, I am using SPI camera module which is giving VGA (640x480) output in RGB or YUV format.

I want to compressed this image in JPEG format so I can send it over wireless easily. I read in i.MXRT1050 application note that this is possible. See following BD.

My question - Is this possible on i.MXRT1170 as well as both containts the PXP module for such conversion. Also, this is practical acheivable approach to do JPEG compression of the RGB or YUV image from some storage flash?

Thanks,

Hitesh

Hello
I hope you are well.

Yes, it is possible to use jpeg library to compress an image on RT1170. Please note that this process is made by the CPU and not the PXP module.
It is possible as well to use some flash for the image source(see sd_jpeg example). You only need to make sure that Flash is not used for XIP.

Best regards,
Omar
