what is needed ?
1. Android smartphone or tablet with BACKSIDE CAMERA - it will also work with front-side cams, but it will be far from convenience.
2. printed trackable MARKER - please download it from << http://goo.gl/xuJQG >> and print it (please follow printing tips below).
(!) printing tips
- to have correct scale of position units (cm) MARKER has to be A4 or A3 full page size - do not set any margins and borders or minimize them.
- A3 size of MARKER is recommended (A4 will work fine for distances less then 3 meters only)
- use white, matte paper (any reflections can cause tracking errors)
How does it work?
When application is installed and running, MARKER is on its place (e.g. attached to the wall), not occluded and well illuminated, just point your device camera on it. Virtual camera will appear in the middle of the MARKER.
On the left side you can choose operation you want to perform with your virtual camera (move, rotate, vertical field of view angle change). To increase/decrease horizontal or vertical parameters just swipe your finger along screen X or Y axis.
(!) In this version only vertical field of view angle can be adjusted, horizontal FOV is calculated from vertical FOV and virtual camera screen aspect ratio, which is locked on 4/3.
To see what is in scope of virtual camera vision you can watch blue lines displayed along virtual camera field of view edges and change your observation position.
In addition you can use virtual camera view (left-bottom corner) where, in an artificial cubic space, an orange box is floating around in the air. This box is your device avatar seen from your virtual camera and the blue frame is this virtual camera field of view. It is easy to catch, when your device is crossing the blue lines, which means, you felt out of your virtual camera field of view.
Phew.. that's quite easy and obvious after 1 minute of testing.
With PhotoVault, privacy is no longer an issue. You can show your photo gallery to all the friends, family, and strangers on the bus that you want because the embarrassing, the secret, the private photos are all hidden from view, tucked away in your Private gallery. In fact, when in Public mode, those hidden photos aren't even part of your photo gallery--their very existence is hidden. And more than just hidden from other people, they're hidden from other apps.
You can even set PhotoVault itself to open in Public mode, so it appears just like a standard photo gallery to any who might pick up your Android or be looking over your shoulder. Until, that is, you enter the password.
You, of course, have complete access to the photos in your Private gallery. You can manipulate them; share them via e-mail, messaging, Facebook, and other social networks; give a slide show; and more. You can do anything with them that you can with those in the Public gallery. The photos are easily transferred from Public gallery to Private gallery and back again with just a long-click on the photo's thumbnail.
If you ever have any questions on how it all works, there are instructions in the app and links to online support and FAQs. Best yet, the developer is actively working on PhotoVault, adding new features and taking requests.
Never be nervous about the privacy of the photos on your Android again with PhotoVault installed.
It is best in this category. The key features are:
- Hidden Mode (hide app icon) feature.

It is primarily designed for use with HD and SD broadcast video cameras but includes settings higher resolutions video cameras.
When working with video, the calculator is calibrated using the resolution of the camera and the size of its sensor. This produces slightly stricter results than some other calculators on the market. But in tests, this calculator has produced pin sharp results which could withstand enlargement in post. Ensuring focus down to the pixel level.
Of course, all cameras have different resolutions and sensor sizes. Another advantage of this application is that it is tailored to work with specific cameras.
