Display system and method for detecting pointed position

A method for detecting a pointed position in a display system comprising:

• a display apparatus including a display screen on which an image is displayed in accordance with image data;
• an operating device for pointing a position, as a pointed position, on the display screen and for capturing an image including the pointed position on the display screen, the operating device being not in touch with the display screen;
• and two or more infrared-light-emitting areas each emitting light having a wavelength in an infrared wavelength region, the infrared-light-emitting areas being provided to the display apparatus, the display system detecting the pointed position on the display screen, based on positions of the infrared-light-emitting areas included in a captured image that is captured by the operating device, the method comprising the steps of:
• providing at least one of the infrared-light-emitting areas within the display screen of the display apparatus;
• and
• causing each of the infrared-light-emitting areas to emit light in a method that allows each of the infrared-light-emitting areas to be distinguished, based on the captured image, by a light-emitting area distinguishing section provided in the display system.

A non-transitory computer-readable storage medium storing a program causing a computer to function as each section in a display system,

• the display system comprising:
• a display apparatus including a display screen on which an image is displayed in accordance with image data;
• an operating device for pointing a position, as a pointed position, on the display screen and for capturing an image including the pointed position on the display screen, the operating device being not in touch with the display screen;
• two or more infrared-light-emitting areas each emitting light having a wavelength in an infrared wavelength region, the infrared-light-emitting areas being provided to the display apparatus;
• a pointed position detecting section that detects the pointed position on the display screen, based on positions of the infrared-light-emitting areas included in a captured image that is captured by the operating device;
• and
• a light-emitting area distinguishing section that distinguishes each of the infrared-light-emitting areas in the captured image,
• at least one of the infrared-light-emitting areas being provided within the display screen of the display apparatus, and
• the infrared-light-emitting areas each emitting light in a method that allows the light-emitting area distinguishing section to distinguish, based on the captured image, each of the infrared-light-emitting areas from one another.
