When an instruction from the user is received or when an event occurs and the head mounted processing apparatus is terminated, a key content pair information register is configured to associate a state of content at the time of the event occurrence with a registration key obtained from an image of a camera at the time of the event occurrence to store them in a memory as key content pair information. When the head mounted processing apparatus is activated, a key content pair restorer is configured to determine whether an image of the camera at the time of apparatus activation is made conformity with the registration key or not on the basis of the key content pair information, and restore the state of the content corresponding to the registration key made conformity with the image in a case where the image is made conformity with the registration key.
