Controlling 3-pin pinhole camera from drone using Arduino
Yellow is often a composite video signal.  Connect an oscilloscope to it and see if it looks like a video signal.

From the Hackaday link:



There's a fourth pad by the yellow wire.  That might be a digital input to trigger an image capture.

Check that extra pad and the yellow wire.  See if either has 5V DC on it.  If so, short it to ground through a low value resistor (1k or so) and see if that causes the module to store a photo on the SD card.

Outside of those possibilities, I don't see much you can do with that thing.  You are kind of limited by not having a datasheet (or a model number or even a manufacturer name to try and find a datasheet.)
