17. Camera

The camera object is a built-in object that provides camera functionality.

Functional overview:

  • Supports still image capture function.

Limitations:

  • It can be used only when the Spresense camera board (ISX012 camera module) is connected.
  • Only JPEG format of QVGA size (Width: 320px, Height: 240px) is available for still images.
