Method of correcting projection image, projection system, and non-transitory computer-readable storage medium storing program

A projection system comprising:

• a sensor;
• a control device configured to execute
• identifying at least one first control point from a plurality of control points configured to correct the projection image based on a position of at least one of hands of a user in a first image which is projected on a projection surface, and which includes the plurality of control points, when a first gesture operation by at least one of the hands of the user is detected based on an output value of the sensor, and
• detecting a second gesture operation by at least one of the hands of the user different from the first gesture operation based on an output value of the sensor;
• and
• a projector configured to execute
• projecting the first image on the projection surface, and
• projecting a second image obtained by moving a position of the at least one first control point from a first position to a second position based on a position of at least one of the hands of the user in the first image on the projection surface when the second gesture operation is detected by the control device.

A non-transitory computer-readable storage medium storing a program, the program being configured to make at least one processor execute processing comprising:

• projecting a first image including a plurality of control points configured to correct a projection image from a projector on a projection surface;
• identifying at least one first control point from the plurality of control points based on a position of at least one of hands of a user in the first image when a first gesture operation by at least one of the hands of the user is detected based on an output value of a sensor;
• and
• projecting a second image obtained by moving a position of the at least one first control point from a first position to a second position based on a position of at least one of the hands of the user in the first image from the projector on the projection surface when a second gesture operation by at least one of the hands of the user different from the first gesture operation is detected based on an output value of the sensor.
