In an adjustment assistance system, an image acquisition part acquires an image captured by a camera. The camera is provided on a car which runs in a hoistway of an elevator. A presentation part indicates on a surface thereof a calibration pattern to be captured by the camera in the hoistway. A detection part detects the calibration pattern in an image acquired by the image acquisition part. An attitude calculation part calculates an attitude of the camera based on an inclination, with respect to an optical axis of the camera, of a normal line to the surface of the presentation part indicating the calibration pattern detected by the detection part.
