Abstract

The invention provides a projector control method and a projector. The projector (200) is provided with: a detection unit (260) that detects the presence or absence of a person present between the screen (100) and the projector (200); a sound output device (271) that emits a first sound when the detection result of the detection unit (260) is "presence"; and a processor (290) that determines whether or not the state in which the detection result is "presence" continues during the first period, and projects the first projection image onto the screen (100) when the state continues, otherwise, if the projection is not continued, a second projection image, which does not include the first projection image, is projected onto the screen.

Description

technical field [0001] The invention relates to a control method of a projector and the projector. Background technique [0002] The projector described in Patent Document 1 has a human sensor. The human sensor detects the presence of a person within the range of light projected from the projector. This projector displays a warning image when a human presence is detected by the human sensor. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2011-43834 [0004] In the technique described in Patent Document 1, a warning image is displayed every time a person is detected or immediately after a person is detected, and therefore, there is a problem that viewing and listening of a projected image is hindered. Contents of the invention [0005] The control method of a projector of the present invention controls a projector having a light source that generates light for projecting a projection image onto a projection surface, wherein presence or absence is detected betw...
