1. An imaging control device, comprising:
an imaging data obtaining unit that obtains imaging data;
a frame setting unit that sets a frame in which position, shape and size are set so as to become appropriate as a range of obtainment of luminance values in the imaging data obtained by the imaging data obtaining unit;
a luminance value obtaining unit that obtains luminance values of pixels included in imaging data that are in a range of the frame set by the frame setting unit;
a representative value calculating unit that calculates a representative value from the luminance values obtained by the luminance value obtaining unit; and
a converting unit that performs gamma conversion of the imaging data obtained by the imaging data obtaining unit, wherein
the converting unit normalizes the imaging data by setting an upper limit value of luminance values on the basis of the representative value calculated by the representative value calculating unit and performs, by means of a hybrid log gamma transfer function according to the upper limit value of luminance values, the gamma conversion of the imaging data that have been normalized.
