How to invert the images both in horizontally and vertically

william.zhou

Hi guy,

I am using DM355, and the format of video source is yCbCr in progressive mode. I wonder how to invert the images both in horizontally and vertically.

It seems HSIZE and SDOFST registers can do this, but the document is dark for me. Give me some helps.Thanks!

Dear William,

Please refer to the RSZ_SEQ register in the IPIPE module of DM355. The register address is 0x1C712BC. There is VRV and HRV bit to do horizontal flip and vertical flip.

Please note that just changing the bits will not help. The addresses have to be set accordingly. The VPFE userguide explains some details about how to do flip inside IPIPE-RSZ.

Regards,

Anshuman
