ABSTRACT:
An imaging device including: an imaging element which comprises a plurality of pixels capable of switching between a linear conversion operation for linearly converting incident light into an electric signal and a logarithmic conversion operation for logarithmically converting the incident light into an electric signal, according to an incident light quantity; a monitor to display an image obtained by the imaging element; an operation section which is operated for specifying an arbitrary area of the image displayed on the monitor; and an inflection point changing section which evaluates an output signal of the imaging element in the specified area, and changes the inflection point which is a boundary between a linear region and a logarithmic region in the output signal of the imaging element, based on an evaluation result of the output signal.
