Document Type and Number:
Japanese Patent JP2021144107
Kind Code:
A
Abstract:
To provide a method of controlling a projector capable of projecting an appropriate image without increasing a burden on a user.SOLUTION: A method of controlling a projector for projecting a projection image corresponding to an input image on a screen by performing scaling processing on the input image includes the steps of correcting a geometric shape of the projection image with a correction amount, calculating a projection surface of the projection image corrected from the correction amount, and changing the scaling processing so that an aspect ratio of the input image is reproduced in the projection surface.SELECTED DRAWING: Figure 11
