Title:
INPUT OPERATION DETECTION DEVICE, IMAGE DISPLAY DEVICE INCLUDING INPUT OPERATION DETECTION DEVICE, AND PROJECTOR SYSTEM
Document Type and Number:
Japanese Patent JP2015212927
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an input operation detection device capable of suppressing a detection error from being larger.SOLUTION: The input operation detection device includes a range-finding part 13, a processing part 15, or the like. The range-finding part 13 includes a light-emitting part which emits light toward an imaging object, an imaging part which images the light reflected by the imaging object, and an arithmetic part and acquires the depth map of a projection area where an input operation is performed. The processing part 15 acquires input operation information indicated by the input operation on the basis of the depth map from the range-finding part 13. The installation angle of the range-finding part 13 is set so that in a Z-axis direction, a position where the optical axis of the range-finding part 13 crosses a projection image is on the same side as the position of the range-finding part 13 with respect to the center of the projection image.
