What are advantages of cameras dedicated for Raspberry Pi (I mean those connected via dedicated camera connector and tape) above those usb webcams ?
Is it just economy advantage (better value for price) ? Or maybe just more compact and lighter ? (what may make a difference e.g. when camera handled by robotic arm)
Or does it also have some (non-negligible) performance/technical advantages? e.g. framerate not possible to achieve via usb webcam, or less cpu overhead ? Therefore, are such advantages non-negligible only for video or also in same cases of capturing still photo pictures ? (I guess might be transfer rate/cpu overhead, maybe power consumption?)
Update: as we know, usb cameras as well as those dedicated for raspberry camera connector vary greatly in features and quality.
Therefore, please consider this question focused and narrowed to interfaces:
- Are there some inherently advantages of 15-pin MIPI camera interface (CSI) connector cameras above usb webcams, because of Raspberry Pi camera interface?
I imagine that it might has something to do that it might omit usb bridge, or protocol might be more lightweight, giving less cpu overhead or latency, but really it's my guess, I have no clue if effects are not negligible, and I have trouble to find out from schematics: https://www.raspberrypi.org/documentation/hardware/raspberrypi/schematics/README.md
