Wearable apparatus

A wearable apparatus comprising:

• a display device of a transmission type mountable to a head of a user;
• an image capture device configured to output a captured image obtained by capturing an image of an area in front of the user;
• a sensor configured to detect a physical quantity;
• and
• a controller configured to display on the display device a guide image indicating an outer edge of the captured image, in a display period from a start timing to an end timing determined based on at least an output signal from the sensor,
• wherein
• the physical quantity concerns a movement of the head,
• the controller is configured to calculate a moving speed of the head, based on the physical quantity indicated by the output signal, to
• set, as a first state, a state in which the moving speed is more than a first threshold value,
• set, as a second state, a state in which the moving speed is more than a second threshold value and equal to or less than the first threshold value, the second threshold value being less than the first threshold value,
• set, as a third state, a state in which the moving speed is equal to or less than the second threshold value,
• set, as the start timing, a timing when the first state transitions to the second state, and
• set, as the end timing, a timing when the second state transitions to the third state.
