E. Connecting the PiCamera to the Rpi board
The Raspberry Pi camera module can take full HD
1080p photo and video, and can be controlled
programmatically. The flex cable is inserted into the
connector situated between the Ethernet and HDMI ports,
with the silver connectors facing the HDMI port. There are
basically two utilities available, ‘raspistill’ and 'raspivid'.
‘Raspistill’ is used for capturing still photographs with the
camera module and ‘raspivid’ is used for capturing video
stream with the camera module. These applications are
command line operated, written to leverage the Multimedia
Abstraction Layer (MMAL) API which runs over
OpenMAX. The MMAL API easily uses the system than
that presented by OpenMAX. MMAL is a Broadcom
specific API used only by VideoCore 4 implementations
[20].
After successful implementation of these steps, the
Raspberry Pi is able to capture the fingerprint and the face
images using the FS88 fingerprint scanner and the PiCamara
respectively.
