PROBLEM TO BE SOLVED: To leave a trace that enables identifying a user who has performed operation to projected image data.SOLUTION: In a projection system 100 communicatively connected with a camera 102, an infrared sensor 103, and a projector 104, an information processing device 101 determines which user an indication object coming into a projection surface belongs to. Then, it takes an image including the determined indication object and a projection image. Image data obtained by such imaging enables leaving a trace that enables identifying the user who has performed operation to the projected image.SELECTED DRAWING: Figure 5
