camera image reversion

[Goodwin]

Dear all,
I came up against a problem. We ported the Camera to our
board, but the camera preview is not correct. The preview image is
mirror reverse. It seem the preview image rotates 180 degrees on
the Y center axis.
Any idears will be appreciated.

Have you confirmed that it's the preview that's rotating it and not
the image coming from the sensor itself? Can you check the camera
image in the Kernel? I have a V4L2 sample app that can take the camera
information from /dev/video0 and loop it back to /dev/video1 if
that'll help..

Regards

Thanks!

Our platform is Android2.2 and we set the camera as the front camera.I
check that the camera image is correct if we set the camera as the
back camera. so, I think the image coming from the sensor is ok.
But,we want set it as the front camera. any idears?

Check out the dox at http://developer.android.com/reference/android/hardware/Camera.html#setDisplayOrientation(int): "preview display of front-facing cameras is flipped horizontally before the rotation, that is, the image is reflected along the central vertical axis of the camera sensor. So the users can see themselves as looking into a mirror."
