Camera Integrated Drone

Hi. I want to build a drone which can take photos and videos. I am not trying to build a FPV drone. I want to take photos and videos on air. Do i still need video transmitter, minimosd or rasperry pi to do this? And both situations (I need and I dont need) can you please tell me how to do it?
Can you advice a camera to use? I will take photos at 15m height.
