On our project (android4.2.2 upgrade to android 5.0.2), the images that taken from 2M camera (Sensor MT9D115)  is weird (pls see the attach images for more info)，the reduplicate rate of this issue is 50%. Could you some suggestion for us ?

It seems to be the frame synchronization issue. Do you have the correct signal levels on the camera interface? Are the signals clear (no noise, no bouncing)? Please check. Do you use the generic parallel interface with Hsync/Vsync signals or BT656 mode? Do you use gated or non-gated pixel clock mode? Please sepcify. Also, please check the Sections 22 and 23 of the attached document for possible camera configuration issues.

Have a great day,
Artur

Thank you!

With some hardwork, the below config should be set in function vidioc_int_g_ifparm_num()

p->u.bt656.nobt_vs_inv = 1;

could give us more explanation about the rootcause ?
