Abstract
An imaging apparatus includes a composite low frequency cutoff filter. The composite low frequency cutoff filter includes a first low frequency cutoff filter, a second low frequency cutoff filter, and an adder-subtractor. The second low frequency cutoff filter receives an output of the first low frequency cutoff filter. The adder-subtractor subtracts an output of the second low frequency cutoff filter from an input to the composite low frequency cutoff filter, and outputs a result of the subtraction to the first low frequency cutoff filter. An output of the first low frequency cutoff filter is outputted as an output of the composite low frequency cutoff filter.
