1. An information processing apparatus, comprising:
a weight calculator configured to calculate a respective weight for each respective sensor of a plurality of sensors on a basis of an Allan variance of the respective sensor in relation to Allan variances of other sensors of the plurality of sensors for each frequency band of a plurality of frequency bands;
a weight combiner configured to
combine respective observation values of the plurality of sensors based on the respective weights corresponding to the observation values of the plurality of sensors, the respective weights being calculated for each frequency band of a plurality of frequency bands, and
output a combining observation value for the plurality of sensors corresponding to each frequency band obtained by combining the respective observation values according to the respective weights calculated for the respective sensors corresponding to the frequency band; and
an output section configured to output an image corresponding to the combining observation value on a display device,
wherein the output combining observation value is further obtained by combining observation values of the plurality of sensors within each weighted frequency band according to the calculated weights of the plurality of sensors for each frequency band,
wherein the weight calculator calculates the respective weight for each respective sensor of the plurality of sensors with which a weighted sum of Allan variances corresponding to respective observation values, depending on a condition directed to the combining observation value, is smallest,
wherein the weight calculator calculates the weights of the plurality of sensors within a length of time that is determined according to an application in which each output combining observation value is used, and
wherein the weight combiner, the weight calculator, and the communication section are each implemented via at least one processor.
