Abstract
There is provided a technology for enabling a user to recognize gradation of a captured image with high accuracy, when the user checks a substitute image displayed in substitution for the captured image. An electronic apparatus divides a captured image into a plurality of partial areas, generates each of histograms for the respective partial areas, the histograms each representing a number of pixels of each gradation, and outputs the generated histogram to an apparatus that displays a substitute image having a data size smaller than a data size of the captured image.
