An information processing apparatus acquires, using an image obtained by capturing a device including a light-emitting marker with exposure times shorter than a time corresponding to one frame, information regarding a position and a posture of the device. The light-emitting marker is caused to emit light for light emission times equal to or shorter than the exposure times. The information processing apparatus causes the light-emitting marker to emit light in a predetermined flashing pattern, and identifies the exposure times on a time axis of the device on the basis of whether or not the image appears in the captured image, to thereby synchronize the exposure and the light emission.
