Abstract:
1. An imaging apparatus comprising: an imaging element having a plurality of pixels for converting incident light into electric signal using a plurality of types of conversion characteristics; and a signal processing section for processing an output signal of the imaging element, the signal processing section comprising: a fluctuation correction section that, when input/output characteristics of the imaging element are subjected to fluctuation caused by at least one of driving conditions of the imaging element, corrects the fluctuation of the output signal of the imaging element; and a characteristic conversion section for uniformly converting the output signal of the imaging element using one conversion characteristic, wherein the fluctuation correction section comprises: a first correction section for correcting the fluctuation according to a computation formula obtained by modeling the plurality of types of conversion characteristics; and a second correction section correcting the output signals located near the switch points of a plurality of types of the conversion characteristics among the output signals whose fluctuation has been corrected by the first correction section, wherein the second correction section corrects the output signals so as to overlap the characteristics of the imaging elements, by using a model formulas of two characteristics on both sides of a switch point.
