| Abstract: | The present disclosure provides a method and device for filtering sensor
data. Signals from an array of sensor pixels are received and checked for
changes in pixel values. Motion is detected based on the changes in pixel
values, and motion output signals are transmitted to a processing
station. If the sum of correlated changes in pixel values across a
predetermined field of view exceeds a predetermined value, indicating
sensor jitter, the motion output signals are suppressed. If a sum of
motion values within a defined subsection of the field of view exceeds a
predetermined threshold, indicating the presence of a large object of no
interest, the motion output signals are suppressed for that subsection. |
