Parallel Camera Interface and BMP

Glenn Vassallo

Other Parts Discussed in Thread: CC3200

I'm looking into the Parallel Camera Interface, but unlike the example provided I need to create a file that is uncompressed, so something like BMP will work.

1) Is it possible to set either of the supported sensors (MT9D111 or the OV3660) into a mode that will save as BMP?

2) I notice the camera_application example code has a driver for the MT9D111 in JPEG sensor mode, is there anywhere else we can obtain drivers for the other modes or other sensor? If not, where do i find details about these modes?

Thanks,

Glenn.

    Hi Glenn,


    undefined ENABLE_JPEG macro in project properties to get data in raw format. Only issue is image size. At max 320*256 image can be store in memory.

    Thanks Aashish,

    For the full sensor resolution, it would only work easily on a custom board with larger serial flash.

    For the CC3200 LaunchPad, can you recommend a method to store the raw format as 320*256 instead of the full 1,600*1,200 ?

    Is it possible to set the sensor to a specific resolution, or will this need to be handled in the code somewhere, and if so, what method is best?

    Glenn.

    Hi Glenn,

    sdk example have code for raw format to store 240X256 image. Please fo through the mt9d111.c. In variable image_size_240_320_preview_cmds_list, image resolution set as 240X256. 

    {1, 0xC6, 0x2727 }, // MODE_CROP_X0_A
    {1, 0xC8, 0x0000 }, // MODE_CROP_X0_A
    {1, 0xC6, 0x2729 }, // MODE_CROP_X1_A
    {1, 0xC8, 0x00F0 }, // MODE_CROP_X1_A
    {1, 0xC6, 0x272B }, // MODE_CROP_Y0_A
    {1, 0xC8, 0x0000 }, // MODE_CROP_Y0_A
    {1, 0xC6, 0x272D }, // MODE_CROP_Y1_A
    {1, 0xC8, 0x0140 }, // MODE_CROP_Y1_A

    You can modify above register configuration for desire resolution. Also you need to change camera.h "#define NUM_OF_1KB_BUFFERS      120" file for image buffer.
