How to display a static image faster.

Hi,

I currently try to use to DLP3000 to project an captured image onto the real scene. My problem is that the time for projecting a new image is too slow. As a result, my system cannot constantly update the new information to the real scene. I use the built-in command LCR_CMD_DisplayStaticImage(filename) for displaying a new image.

I would appreciate any suggestions. 

Thank you

  • Hello Quang,

    To speed up, you have to use ( mini HDMI connector ) Digital Video Interface to send your information. 

    LCR_CMD_DisplayStaticImage(filename) - 

    For this API the DM365 needs to parse the incoming BMP file and then update it over the it's video frame buffer. So there is no other way to shorten the load time.

  • Hi Sanjeev,

    Thank you very much for your suggestion. Would you please provide me some hints or documents for loading an

    image from the computer to the DLP using HDMI cable since I cannot find any instructions relating to this

    problem in the API sample code . Also, my project need to capture a video using the camera attached to the DLP

    lightcrafter board and then to display it using the projector so the image loading process is very important. Thank

    you again

    Regards,

  • Hello Huy,

    For HDMI you don't need to send or use API command, if you connect to HDMI of PC to the LightCrafter it detects as monitor device.

    Then your desktop background image itself will be the pattern data that is going into the LightCrafter.
