Wearable device, control method and non-transitory storage medium

A control method executed by a wearable device mountable on a head, the control method comprising:

• capturing scenery in front of a user by at least one imager;
• detecting a shield from a captured image by the imager;
• displaying the captured image in at least one display arranged in front of an eye or both eyes of the user;
• determining that the shield is moved from an inside to an outside of an imaging range of the imager and executing acquisition of the captured image upon
• movement of the shield from the inside to the outside of the imaging range of the imager, and
• disappearance of the shield from the captured image;
• causing the imager
• to execute zoom processing based on a predetermined operation of the shield inside the imaging range, and
• not to execute the acquisition of the captured image when the shield disappears from the captured image by the zoom processing;
• estimating a locus of the movement of the shield in which the shield moves from the outside to the inside of the imaging range, then stops for a predetermined time and moves from the inside to the outside of the imaging range;
• and
• setting a starting point of the locus at which the shield starts moving from the inside to the outside of the imaging range after stopping for the predetermined time to a position to be focused in the acquisition of the captured image.

A wearable device mountable on a head, the wearable device comprising:

• at least one imager configured to capture scenery in front of a user;
• and
• at least one controller configured to detect a shield in a captured image by the imager, wherein
• the at least one controller is further configured to execute acquisition of the captured image upon movement of the shield from an inside to an outside of an imaging range of the imager,
• the at least one controller is further configured to:
• estimate a locus of the movement of the shield in which the shield moves from the outside to the inside of the imaging range, then stops for a predetermined time and moves from the inside to the outside of the imaging range, and
• set a starting point of the locus at which the shield starts moving from the inside to the outside of the imaging range after stopping for the predetermined time to a position to be focused in the acquisition of the captured image,
• the locus of the movement of the shield is a locus of the movement of an end portion of the shield, and
• the at least one controller is configured to estimate a change point of the locus of the end portion of the shield as the starting point of the locus before the shield moves to the outside of the imaging range.
