digital zoom function in Imx8qm

yibhan — Tue, 03 Nov 2020 02:32:34 GMT

Hi guys,

I am considering digital zoom camera funtions in IMX8QM and kernel 5.4.47

I have searched community for my concerns but answer would be possible in ISP of imx6, but I am going to use imx8q. In my understanding, there is no IPU in imx8q, So, my question is it is possible to use digital zoom function in imx8qm ? I think it is possible, but I couldn't find some of information. Could you guide me some of detail such as pdf or docs or links.

I am looking forward your help.
