| Abstract: | An electronic device includes a memory configured to receive data
representing light intensity values from pixels in a focal plane array
and a processor that analyzes the received data to determine which light
values correspond to triggered pixels, where the triggered pixels are
those pixels that meet a predefined set of criteria, and determines, for
each triggered pixel, a set of neighbor pixels for which light intensity
values are to be stored. The electronic device also includes a buffer
that temporarily stores light intensity values for at least one
previously processed row of pixels, so that when a triggered pixel is
identified in a current row, light intensity values for the neighbor
pixels in the previously processed row and for the triggered pixel are
persistently stored, as well as a data transmitter that transmits the
persistently stored light intensity values for the triggered and neighbor
pixels to a data receiver. |
