라즈베리파이 카메라 활성화하기

1. 라즈베리파이에 카메라를 연결한다. 

2. $ sudo raspi-config

Raspberry Pi Software Configuration Tool(raspi-config)

\

5. Interfacing Options(인터페이싱 옵션)를 선택한다.

카메라를 선택한다. 

예를 선택한다. 

enabled 확인한다. 

Finish 버튼을 누른다. 

리부팅 <예>를 누른다. 

카메라 촬영하기

$ sudo raspistill -o cam.jpg

5초 후 사진을 찍는다. (타이머 기본값 5초)

카메라가 실행되고 5초뒤 종료된다.

기본폴더 /home/pi/cam.jpg 이미지 파일이 생성된다. 

타이머 변경

타이머 기본값은 5초. 옵션은 t , 단위는 밀리초 

타이머를 1초로 설정

$ raspistill -t 1000 -o cam.jpg

키기 변경

옵션 w(넓이), h(높이) 

$ raspistill -w 200 -h 200 -0 cam.jpg

밝기 조절

옵션 br 

밝기를 50%로 설정할때 

$ raspistill -br 50 -o cam-br-50.jpg

화면 뒤집기 

옵션 hf(수평) vf(수직) 

수평 뒤집기

$ raspistill -hf -o camhf.jpg
