We provide two HALs under Android 4 for CMOS, CCD and USB cameras. The
CCD and CMOS cameras share the same HAL.
1) camera.cmos.so – this is for the CCD and CMOS cameras
2) camera.usb.so – this is for the USB cameras
When Android 4 is loading it will automatically check whethere a USB camera is
connected. If a USB camera is connected Android will call “camera.usb.so” to load the
USB camera otherwise it will call “camera.cmos.so”.
If you need to load your own HAL or stop the above behavior you can edit item
“ro.sf.auto_detect_camera” in the file “/system/build.prop”. Setting it to “no” is to stop
that behavior.
In our system Android 4 will load “camera.mini210.so” under “/system/lib/hw” when
it is loading.
Notes to users as for development of USB camera applications:
1) We tried Logitech’s C270 USB camera and it worked. Usually if a camera’s data
format is YVYV/YUY2 it should work with the 210 boards. If a camera’s data
format is different you might need to change the value of the item
“ro.kernel.android.cam_yuy2=n” in the file “/system/build.prop”.
