라즈베리 파이 5M 카메라 - 지름도착!

Camera Serial Interface - CSI

Mobile Industry Processor Interface - MIPI

[링크 : https://en.wikipedia.org/wiki/MIPI_Alliance]

라즈베리 파이에 장착된 인터페이스로 CSI DSI중에

DSI는 구하기 드럽게 힘들고 -_-a

아무튼 카메라는 구할 수 있으니 일단 이녀석부터!

사이즈는 이정도!

CAMERA 라고 써있는 녀석을 손톱으로 톡! 해서 들어 올리고

핀 방향을 잘 맞춰서 꼽고

걸쇠를 다시 내려주면 끝!

지원가능한 해상도는 아래와 같은데..

5M에서도 15fps가 나오나보네? ㄷㄷㄷ

[링크 : http://www.ovt.com/uploads/parts/OV5647.pdf]

120 프레임 보고 싶은데.. 잘 안되는거 같네..

fps를 1로 해도 부드럽게 나온다.. 30fps 고정인가?

csi의 경우 /dev/video 처럼 v4l로 인식이 되지 않아 콘솔상에서 파이프라인을 통해 보내야 할 듯 하다.

Basically the cable specifications are :

Type : FFC / FPC (Flat Flex)

Wires : 15 

Pitch : 1mm

Contacts : Type B (This means you have the contacts at opposite sides of the cable. So one is at the top and the other at the bottom)
