Abstract: The present disclosure relates to an HMD, a control method for the head mounted display, an information processor, a display device, and a program that make it possible to estimate camera parameters of a camera mounted in the HMD without the awareness of a user wearing the HMD. At a timing when the HMD is displaying content including a VR image or an AR image, the camera mounted in the HMD captures an image of a calibration pattern displayed on an external display, executes calibration on the basis of the captured image of the calibration pattern, and estimates the camera parameters. At this time, the calibration pattern displayed on the external display is displayed with dimensions according to a positional relationship between the HMD and the external display. The present disclosure is applicable to the HMD.
