SOLVED Low light MIPI camera supporting 720p60

STiwana

Hi,
I recently came across the VEYE cameras and they seem to show potential for a product that we're working on. We need to use the cameras with our own FPGA board with a RPi style 15 pin MIPI CSI2 connector.

Our main requirements are as follows:

MIPI CSI2 interface (15 pin) compatible
Very good low light performance
Able to support 720p60
Auto Exposure/White balance (camera internal)
In-camera HDR if possible
I2C sequence of commands to start the camera in above settings. We don't necessarily need the datasheet if we can just get a list.

I have seen your cameras based on IMX385, IMX327 and IMX462, however they only state 1080p30 as the output resolution. I am wondering if they are also configurable in 720p60 output mode with above options (Auto Exposure, HDR)?
Kindly help guide to the correct module.

Thank you.

Hi，Thank you for your recognition, VEYE series does not support 720p@60fps, sorry.

Hi,

Thank you for your response. Ok, understood about no support for 720p60.

Alternatively, we could probably use 1080p30 also (need to look further and discuss with team). We could probably crop to our required image size inside the FPGA. 60fps is not critical.

To that end, I have few questions:

Is it possible to output HDR imagery over the MIPI interface (IMX327S/IMX385/IMX462) or do we need to do it inside our own fpga?
Is the I2C command set open, such that we could do the camera module configuration from our baremetal application?
Can you confirm my understanding that in this case our FPGA will be talking to the onboard ISP chip on your camera board over I2C, and not directly to the camera.
Roughly how much is the added latency due to your onboard ISP on the boards?
The auto exposure and white balance will be handled by the onboard ISP, and will not need to be handled by our FPGA, correct?

Thanks.

These 2 modules support DOL HDR inside. You can enable this function via shell script.

Is the I2C command set open, such that we could do the camera module configuration from our baremetal application?

Yes, the I2C toolkit is open source.

Can you confirm my understanding that in this case our FPGA will be talking to the onboard ISP chip on your camera board over I2C, and not directly to the camera.

YES. Directly to ISP and my FPGA, not to sensor.

Roughly how much is the added latency due to your onboard ISP on the boards?

60-80ms I think. Because DOL WDR and 3D denoise functions.

The auto exposure and white balance will be handled by the onboard ISP, and will not need to be handled by our FPGA, correct?

Yes.

@stiwana This question has been asked for a long time and the status has not been updated. I will mark the status as solved, so you can follow up again if needed, or just open the question.
