Title:
PROJECTION IMAGE DISPLAY APPARATUS AND IMAGE DISPLAY METHOD
Document Type and Number:
WIPO Patent Application WO/2016/075796
Kind Code:
A1
Abstract:
The purpose of the present invention is to reduce erroneous recognition and false negative detection of a user's operation due to the effect of outside light, etc. A device 150 to be operated projects a display image onto a projection surface. A camera 102 captures an image of the projection surface. On the basis of the image data captured by the camera 102, an operation-detectable region identification unit 107 identifies the region of the display image projection coverage where operation by operation objects can be detected, as well as the region of the display image projection coverage where operation by operation objects cannot be detected. A finger contact position detection unit 105 and a pen contact position detection unit 106 detect operation by an operation object on the basis of the image data captured by the camera 102. The device 150 to be manipulated then displays the region that is identified by the operation-detectable region identification unit 107 as being where operation by operation objects can be detected, in such a manner as to differentiate that region from the region where operation by operation objects cannot be detected. Further, the device 150 to be manipulated changes the display position of the operation object so that the operation object is displayed within the region where operation by operation objects can be detected.
