There is provided an image processing apparatus, which are capable of controlling a motion of a robot with high accuracy without coding a complex robot motion control program point by point. First coordinate values being each of position coordinates of movement destinations of an end effector of a robot are acquired. Second coordinate values being position coordinates of a target are detected based on an image of the target captured at each of the movement destinations. Selections of a plurality of operations which a robot controller is made to execute are accepted out of a plurality of operations including at least an operation of moving the end effector to the first coordinate values or an operation of moving the end effector to the second coordinate values, to accept a setting of an execution sequence of the plurality of operations the selections of which have been accepted.
