The stereoscopic displaying apparatus (1) corrects an assembling error of the stereoscopic displaying apparatus (1) based on the left imaging parameter, thereby eliminating the influence of the assembling error on the display effect of the stereoscopic displaying apparatus (1). Similarly, by installing the right camera 32b at the right eye position, capturing a stereoscopic image displayed by the stereoscopic display apparatus 1 to acquire a second image change, and performing a corresponding image process on the second image change It is possible to obtain a right image parameter satisfying a predetermined condition.
