1. An electronic apparatus, comprising: a projection unit that projects a test image and a projection-target original image onto a projection surface; an imaging unit that captures a photographic image of the projection surface onto which the test image is projected by the projection unit; a reflectance calculating unit that calculates a reflectance of the projection surface based upon the photographic image of the projection surface captured by the imaging unit; and a control unit that adjusts a correction quantity representing an extent to which the projection-target original image is to be corrected, so as to correct influence of the reflectance on the projection-target original image, based upon pixel values of an area of the photographic image of the projection surface excluding an area of the projection surface where the reflectance is calculated as low by the reflectance calculating unit.
