It seams phantom 3 standard uses sony imx377eqh5 sensor. I am not sure but specification looks similar http://www.sony-semicon.co.jp/products_en/IS/sensor2/img/products/IMX377EQH5_ProductSummary_v1.5_20150414.pdf

kazan417 commented 7 years ago

maybe IMX378

kazan417 commented 7 years ago

also imx117 is another variant

kazan417 commented 7 years ago

IMX078CQK more one candidat

There's a list of the sensor models on wikipedia: https://en.wikipedia.org/wiki/Exmor

Would be nice to know what kind of output the sensor has.

EDIT: To narrow down the list:

P3 pro was released in April 2015, so the sensor must be released earlier
The sensor has 12.76 M px total, 12.4 M effective px, as mentioned here.

IMX378 -released in September 2016, so can't be it.

IMX377 - rel. in April 2015, so DJI would have to cooperate with Sony before release, unlikely. Also 12.2 MP effective, so lower than what DJI claims

IMX117 - only 12 MP, lower than what DJI claims

IMX078CQK - released in February 2011 and matches all DJIs parameters. I'd say it's most likely candidate.

@mefistotelis it would be nice to hookup another camera and just use the gimbals motherboard to accept another cameras input. also to find a light enough camera with a lot of optical zoom for under a thousand dollars. then one wouldn't need a $30,000 drone setup to have some optical zoom.. would be cool to have a gopro with x100 zoom and light enough to attach to the phantom 3

I don't know enough about image sensor technologies to describe the protocol correctly.

Regarding switching camera, it might be possible to connect other cameras to OFDM - the image is transmitted over USB. Not sure whether it is any standard USB video transmission.

Definitely not easy to connect another camera to gimbal top board.
