TDA2EVM5777: Integrating Camera Sensor without ISP on it with TDA2x

Part Number: TDA2EVM5777
Other Parts Discussed in Thread: TDA2SX

Hi,

I have TDA2X EVM Board (with TDA2SX SOC), And I have tested OV10635 Camera Module on it. I am successfully able to run the camera usecase.

Now, I want to use IMX290 camera module on the same board. But, as per documentation of IMX290. It does not have ISP with it. I have few questions.

1. What is main role of ISP in general ?

2. TDA2SX does not have on chip ISP But, TDA2PX has on chip ISP

- Does it mean, We can use IMX290 on TDA2PX ?

3. Can we implement basic ISP functionalities on TDA2X itself on software side? Does it make any sense?

4. Can we use VIP or DSS, for basic ISP functionalities like RAW to YUV Conversion ?

5. What shall i do, if I want to use IMX290 on TDA2x ?

    Hi Sagar,

    IMX290 module is from Geosemi and the module had an ISP.

    Where exactly do you see the contrary mentioned in SDK documentation?

    ISP's role is convert image sensor's output to a human/machine usable format.

    IMX290 can be used on TDA2Px, but we do not have SW support for this sensor. You will need to add sensor driver and ISP support for this sensor.

    You may implement a SW ISP. It is possible but usually it is low quality and performance compared to hardware ISP.

    RAW to YUV can not be done on DSS or VIP

    Hi Rishabh,

    1. Can you send me link for IMX290 from Geosemi which has ISP and tested on TDA2X EVM board ?

    2. My main concern is , If i choose IMX290 as Camera Sensor and and i want to process raw data from this sensor using my algorithm

    and then display it over HDMI. 

    Is it possible with just the help of VIP/DSS ?

    3. Can we give raw data as input to Display Link?

    4. Can we use IMX290 without using external ISP on TDA2X EVM board?

    4. If there is no ISP present for camera sensor and also ISP is not present on Processort SoC, What all problems we may face in future?

    Regards,

    Sagar

    Hi Sagar,

    You need to contact Geosemi for IMX290 module. I don't have a link for it.

    You will need ISP to convert raw image to YUV.

    Display does not support raw input.

    You cannot use raw sensors without ISP. ISP can be external or internal.

    Hi,

    I haven't heard back from you, I'm assuming you were able to resolve your issue.
    If not, just post a reply below (or create a new thread if the thread has locked due to time-out).
