How to configure a low power camera to nRF52840 controller?

I am trying to connect a low power camera Himax HM0360 to nRF52840 dk. In the camera device specification, it is mentioned that it provides I2C serial interface and full speed is 1MHz.Is this speed enough to transfer image to controller? What other things should be considered to interface camera to controller? The answer from user eriknorth here, for a similar question explains that it is hard to transfer the image within a few cycles. So, to ease this constraint, should the camera have a internal buffer to save data? Is anyone successful in configuring a camera to nRF52840-dk?

    Sorry for the long response time.
     

    .Is this speed enough to transfer image to controller?

    It says 1MHz maximum possible, So it should work take a look at the specification of nRf52840 here (Page No:449).

    What other things should be considered to interface camera to controller?

    For transferring high resolution image/video, I think you need to set bandwidth and latency reasonably.
    Take a look at this sample from our old sdk for you reference.
