Interfacing TMS320DM365 with OV7955

Other Parts Discussed in Thread: TMS320DM365

Hi all !

We are trying to interface TMS320DM365 with CMOS sensor OV7955.  We need to capture still images from the sensor and process it. So, Are there any specific settings which has to be made in TMS320DM365 for still image capture? And also, Since OV7955 outputs YUV data, can we skip ipipe module and directly store the images from isif module into RAM? 

Thanks and Regards,

Arpitha Mohan

    Hi Arpitha,
    1. Are there any specific settings which has to be made in TMS320DM365 for still image capture?
       When you say still Image, I assume  you are looking for JPEG  Images(like a still camera). In that Case Web GUI supports Still Image Capture of JPEG. Please refer GUI guide available with IPNC. 

    2. C    an we skip ipipe module and directly store the images from isif module into RAM?
     Yes, you can store YUV data to the buffers directly by skipping IPIPE module. To do this ISS/ISP capture need to be set for DDR mode instead of ISIF mode (refer ISS - TRM).
       
        In this case I am not sure why you want to skip IPIPE module which runs some Quality related algorithm like NSF on YUV/RAW data.  It is possible to process YUV data     with/without skipping IPIPE module.  

        Also, how you are planning to access the yuv data if it is available on RAM? is there any plan for it? Can you elaborate your use case, so that I can  understand it better.

    Hi Prashanth,

    First of all Thank you very much for your reply.

      Are there any specific settings which has to be made in TMS320DM365 for still image capture?

      >> When you say still Image, I assume  you are looking for JPEG  Images(like a still camera). In that Case Web GUI supports Still Image Capture of JPEG. Please refer         GUI guide available with IPNC. 
      >>  OV7955 gives the image in YUV format. So at this stage We are looking for YUV data and not JPEG images, though our final intention is to convert this YUV  image            into JPEG Image. But we have not yet  figured out how to receive this YUV image from the sensor. So could you help us in finding out a way? 

     And  also retaining the IPIPE module seems appropriate to me as well. Thank you for the suggestion. Help me in the above regard.
    P.S: Since i am a fresher i am unable to figure out things. So sorry if my queries sound silly.

    Regards,
    Arpitha

    Hi,

    Sorry for late reply.

    Please install ImageTuningTool provided with you IPNC, this will give you the options to YUV as well as RAW data in web GUI.

    Follow the user guide of ITT(ImageTuningTool).

    you can find userguide after installation in path "ImageTuningTool_DM36x\Documents"
