A sparkle contrast correcting method includes a step of acquiring a first sparkle contrast that is caused by an anti-glare layer that is disposed on a surface of an electronic display and information that represents a first measurement condition, the first sparkle contrast being used as a comparison standard and being measured in the first measurement condition by using a first imaging lens that images emitted light from the anti-glare layer and a first two-dimensional image sensor on which the emitted light is imaged, a step of acquiring a second sparkle contrast that is caused by the anti-glare layer and information that represents a second measurement condition, the second sparkle contrast being used as a comparison target and being measured in the second measurement condition that differs from the first measurement condition by using a second imaging lens that images emitted light from the anti-glare layer and a second two-dimensional image sensor on which the emitted light is imaged, and a step of correcting the second sparkle contrast, based on a ratio between the first measurement condition and the second measurement condition for comparison with the first sparkle contrast.
