Image display system, image display method, movable object including the image display system, and non-transitory computer-readable medium

An image display method employing an image display system, the image display system including an image display unit configured to display an image, a projection unit configured to project in a target space a virtual image corresponding to the image with an output light of the display unit, and a body unit to which the display unit and the projection unit are provided,

• the image display method comprising an image producing processing of producing the image displayed on the display unit,
• the image producing processing including:
• a first correction processing of correcting, based on a first orientation signal, a display position of the virtual image in the target space, the first orientation signal being indicative of a first orientation change of the body unit;
• and
• a second correction processing of correcting, based on a second orientation signal, the display position of the virtual image in the target space, the second orientation signal being indicative of a second orientation change of the body unit of which change rate is faster than that of the first orientation change,
• the image display method performing the first correction processing and the second correction processing at different timings.

A non-transitory computer-readable medium recording a computer program for instructing a computer system to execute an image display method employing an image display system,

• the image display system including an image display unit configured to display an image, a projection unit configured to project in a target space a virtual image corresponding to the image with an output light of the display unit, and a body unit to which the display unit and the projection unit are provided,
• the image display method including an image producing processing of producing the image displayed on the display unit,
• the image producing processing including:
• a first correction processing of correcting, based on a first orientation signal, a display position of the virtual image in the target space, the first orientation signal being indicative of a first orientation change of the body unit;
• and
• a second correction processing of correcting, based on a second orientation signal, the display position of the virtual image in the target space, the second orientation signal being indicative of a second orientation change of the body unit of which change rate is faster than that of the first orientation change,
