How can I zoom in a camera frame

[Vinos]

Environment:RT1176 with a MIPI screen and a MIPI camera.

I've implemented the SDK example "csi_mipi_yuv_cm7",and now I want to zoom in and zoom out the a specific part of the camera frame as a camera app does in a phone.

Do you have any library and how can I achieve this?It seems PXP can only scale a frame.

Hi @Vinos ,

PXP can only scale down. The 2DGPU doesn't support scaling a picture. You have to use software to scale up.
