1. A data processing device, comprising:
processing circuitry configured to:
acquire first data including time-series image data, wherein the first data corresponds to a temporal change of an arc of a circuit interrupter;
derive first feature information based on a multidimensional array of n dimensions based on the first data; and
control the circuit interrupter by supplying a control signal to the circuit interrupter based on the first feature information, wherein,
n is an integer not less than 3,
a first axis of the multidimensional array is related to time,
a second axis of the multidimensional array is related to a first coordinate value of a first spatial axis in space,
a third axis of the multidimensional array is related to a second coordinate value of a second spatial axis in the space, the second spatial axis crosses the first spatial axis,
a fourth axis of the multidimensional array is related to a chromaticity coordinate value,
the first feature information includes a plurality of persistent feature values in a persistence diagram,
a time of one of the plurality of persistent feature values is different from a time of another one of the plurality of persistent feature values, and
the persistence diagram corresponds to a dispersion state of at least a portion of the first data, and is derived based on values of the multidimensional array.
