Patent number: 10268284Abstract: In an image display system including a pen and a projection-type image display device having an interactive function, attributes such as a color and a thickness of a line or a figure to be drawn can be more flexibly switched at a lower cost. According to a typical embodiment, a pen-shaped pointing tool has a light emitting portion which emits non-visible light with a predetermined wavelength. The projection-type image display device has an interactive function unit which, from image data captured by a sensor performing image-capturing based on reflection light of the non-visible light with the predetermined wavelength reflected on the screen, recognizes a position of and a content of a light emitting pattern emitted from the pointing tool onto the screen, and executes process contents which are different from one another, based on the recognized position of and content of the light emitting pattern.Type: GrantFiled: July 29, 2015Date of Patent: April 23, 2019Assignee: Maxell, Ltd.Inventors: Shuhei Kobayashi, Shinji Onodera
