Projector, control method for projector, and program

Abstract

To solve the problem that a use condition under which projection size can be measured is limited when the distance between a projection surface and a projector is measured using a handle.SOLUTION: A projector comprises: an optical device that emits image light indicating an image; a processing device; and a housing accommodating the optical device and the processing device. The processing device displays, on a projection surface using the optical device, a first image for selecting one method of a plurality of methods for determining a size of the image on the projection surface, the plurality of methods including a first method and a second method, displays, on the projection surface using the optical device when the first method is selected, a second image whose length is to be measured, and displays, on the projection surface using the optical device when the second method is selected, a third image whose width is changeable.SELECTED DRAWING: Figure 6
