ABSTRACT:
An imaging device including an imaging element having a plurality of pixels for switching a linear conversion mode for linearly converting incident light to an electric signal and a logarithm conversion mode for logarithmically converting incident light to an electric signal on the basis of incident light intensity,a conversion unit for converting and outputting a reference electric signal converted logarithmically and outputted from the imaging element to an electric signal obtained by linearly converting an electric signal before logarithm conversion,a correction unit, when an electric signal converted logarithmically and outputted from the imaging element is varied from the reference electric signal, for correcting it so as to coincide with the reference electric signal, and a circuit for giving the corrected electric signal to the conversion unit.
