Raspberry Pi のカメラが届いた。

11:27 pm Raspberry Pi, お買い物

Raspberry Pi にはカメラ専用のインターフェースが用意されていて、専用のカメラも売られている…

調べたら、eBay で China Version だけど深圳からの送料込み 1,800円程度で購入できることがわかった。

ちなみに日本で普通に買うと 3,700円くらい。

この金額で、5メガピクセルで、2,592×1,944ピクセルの画像と、1080p、H264形式で、1秒間に30フレームの動画を記録できるんだからまぁ買いでしょ。

で10月30日に注文した。11月 8日のきょう、それが届いた。

『Raspberry Piカメラのセットアップ方法』を参考にセットアップ。

[code]
pi@raspberrypi ~ $ sudo apt-get update
pi@raspberrypi ~ $ sudo apt-get upgrade
[/code]
とした後
[code]
pi@raspberrypi ~ $ sudo raspi-config
[/code]
で camera を Enable にする。終了すると再起動が行われるけど、もうこれで写真が撮れる。

[code]
pi@raspberrypi ~ $ raspistill -o image.jpg
[/code]

H264フォーマットで5秒間の動画なら
[code]
pi@raspberrypi ~ $ raspivid -o video.h264
[/code]

なんて簡単なんでしょう。

それぞれのコマンドのオプションは以下。随分多機能みたいです。
