Stabilization Evaluation Equipment (STEVE) - a device to check and measure the quality of image stabilization systems in cameras.
STEVE is calibrated to exhibit the best performance at the most signi! cant frequency/ ampiltude combination of the human tremor of 4 Hz and 0.2 degrees. The whole range of the frequency and the angle of the movement corresponds to the properties of the typical tremor. For the initial setup,
the mounting stage allows to adjust the camera position. The movement parameters of the two axes can be set up separately. Moving about a single axis (yaw or pitch) is possible, as well as simultaneous operation in parallel or antiparallel way. Both, simple sine shaped motion and individual curves (e.g. to simulate a real handshake) can be realized and logged.
To determine the in" uence of the handshake it is neccessary to combine STEVE with a test chart. We recommend our AF-Box.
