POSITION DETECTION DEVICE, PROJECTOR, AND POSITION DETECTION METHOD

摘要

A position detection device capable of preventing an operation that is not intended by an operator from being detected as an input is provided. The position detection device includes: a detecting section that detects an indicator that performs an operation with respect to a screen, and a target different from the indicator; an imaging section that images a range including the screen to form a captured image; and a control section that detects a motion of the indicator based on data on the captured image of the imaging section to determine whether or not to detect an operation based on the indicator as an input.

1. A position detection device comprising:
a detecting section that detects an indicator and a target different from the indicator, the indicator performing a first operation with respect to an operation surface, the target performing a second operation with respect to the operation surface; an imaging section that forms a captured image obtained by imaging a range including the operation surface; and a control section that detects a motion of the target based on the captured image to determine whether or not to detect the second operation performed by the target as an input.
