Original question:

Linux/TDA2SX: OV2311 support for TDA2x

TDA2SX: Software Implementation of AEC/AGC on TDA2X EVM

Part Number: TDA2SX


Hi,

I am referring to previous post where OV2311 is connected to TDA2X via SerDes. Assume, custom drivers has beed written and  We are able to receive data from OV2311 on TD2X.

I am connecting OV2311 without any ISP, as it is monoschrome sensor and does need much ISP functionalities.

As I said, I am able to get data and able to visualize on HDMI (I have written a custom OV2311 camera display usecase).

In OV2311, we have only 2 controls that user can configure to get better image, Gain and Exposure. These 2 parameters, currently i am manually controlling via user input and able to get well illuminated image in dark scene and bright scene. 

I want this to be dynamic control. I understand i have implement some of ISP functionalities in software like AGC/AEC. I want more information where i can implement it, IPU side, DSP side, A15 side or anything else? Which will be best way to get optimum performance?

Please suggest, How can i achieve dynamic control?

Regards,

Sagar

    Please check with OV if the sensor supports statistics or histograms as part of embedded metadata. If it does, you may use that information to develop your AE algorithm. You may implement it on IPU or A15 or DSP. That is a SW decision you will need to take. TI does not support 2A on ISP-less devices.
