Change a wide FOV RGB camera to the D430 module
Is there any reason why the FOV of the RGB camera on the D430 module is smaller than the FOV of the IR camera on the D430 module?
Can I change a wide FOV (similar to or larger than the FOV of the IR camera) RGB camera to the D430 module? If yes, how can we do it?
Do you have its OEM? Do you know its vendors? Could you introduce Intel HW partners for it?
Thanks,

On the D415, where the RGB imager is integrated into the depth module board instead of being attached separately, the RGB and the IR imager use the same component. On the D420 and D430 depth modules, a different 'wide' IR imager is used that provides a wider field of view. So when depth is aligned to color on the cameras with a wide view, the RGB FOV is used.
An integrator who was constructing their own design from individual parts said "From my understanding these [imagers] are just standard MIPI CSI-2 camera modules (OV9282 and OV2740), so any modules with similar spec (MP/s, etc.) should work".
The OV numbers quoted refer to the OmniVision part numbers of the imagers in the cased D435 camera. RGB is OV2740 and IR is OV9282. On the D415, RGB and IR are both OV2740.

I do not have information on that subject. I would speculate that it might be related to the shutter and its effect on exposure timing. The OV2740 has a "rolling" shutter, whilst the wide OV9282 has a faster "global" shutter. So there could be an impact on exposure timing, I would guess, if both RGB and IR used a fast global shutter.
