Tilt Sensor

[GaryT85]

here's a spanner for the works...(someone who hasnt been in work for 12 hours so far and still not home should make sense of it, or i'll be back to it later...)

try a 'normal' horizontal held photo, try a 'vertical' photo, then keep rotating the camera so you get a photo with the phone 'upside down'....

i just did and it gives me the photos back in the gallery the right way up...

From my understanding the n95 does rotate the image based on how you take the photo. Want proof? Go to the camera settings and theres an option right there that says "Rotate image". Whether it uses a tilt sensor or software is a question mark.

It was a couple of lines so I would know it had the image the right way and not upside down. This was in the middle of a large office with light coming from a window pretty much directly behind me.

I would like to see some evidence of it being done with software and not a mercury style switch because to analyse an image and get it right every time is awesome. And it does it so fast too.

Exactly.... How does one discover the truth? This is an X-File for the time being..

If it is some sort of hardware sensor- how do any of you explain the fact that sometimes it gets it wrong?

hmmmmm....?

A few reasons I can think of but without more details of how the "wrong" photos were taken I would be guesing.

Was the phone level with the subject for instance or was the picture taken with the phone pointing straight down, that would be sure to fool the sensor. Or was the photo taken somewhere with low gravity, or from a moving vehicle, perhaps somewhere with a strong magnetic field?

This might sound a little off topic, but if it does have a hardware sensor, it feels as if it's another addition to the many things that could break if you drop your phone.

I could only imagine how stuffey it must be inside with everything so compact.

A HW sensor could easily make a mistake, an example that comes to mind would be the case where although the phone is in landscape (or portrait) mode, your hand happens to be moving slightly and thus the sensor would become momentarily confused. This example can easily be pictured when considering the fact that typical sensors are constructed using an accelerometer type device (spring with a weight at one end, which causes changes in either magnetic or electric flux), or even a mercury (i doubt it) filled sensor.

either way its my educated guess (im an electrical engineer), that it would be cheaper and easier to use a HW based sensor that a SW based sensor. But I like to keep an open mind so it is possible that it could be SW based.

That makes sense.
