TIDM-TM4C129CAMERA: Higher resolution for still image capture

Part Number: TIDM-TM4C129CAMERA

Hi,

The reference design achieves QVGA resolution (320x240) at 30fps.

Is it possible to achieve higher resolution for still image capture?

    Hi,

      The maximum resolution for the LCD controller is 2048 x 2048 pixels which is much higher than 320 x 240. There should be no problem if your chosen resolution is within the spec limit.

    Hi,

    Thanks for the reply. There has been a confusion here.

    I was asking about the camera side input resolution rather than the LCD controller. Can you please let us know the maximum image sensor resolution that can be interfaced for still image capture

    Hi,

      How high is your resolution? For this TI-design, one line is buffered before sending to the LCD controller. For 320 pixels per line the amount of SRAM needed is 1280 bytes only. It really depends on how your application as to where you are sending the captured camera to and how you will process the data. I really don't think there will be a problem to increase the resolution higher. For example, for 480 pixels, the SRAM needed is 1920 bytes. The uDMA is used to efficiently transfer the data. Using the udma_demo example for reference, the uDMA has the throughput in the range of 100M bytes per second. I don't think the amount of data captured from camera will be problem.
