Abstract
A control method for a first projector includes receiving designation of a head image of a third user image to be projected in a first size in a projection image in a second user group image, calculating a second size indicating a size of the head image in the projection image when the size of the head image is changed, and adjusting, based on a first ratio, which is a ratio of the second size to the first size, an enlargement ratio of the projection image with respect to the second user group image such that the head image is displayed in the first size in the projection image.
Claims8
A control method for a projector, comprising:
- receiving designation of a target image to be projected in a first size in, in an input image, a projection image obtained by a projector projecting the input image onto a projection surface;
- calculating a second size indicating a size of the target image in the projection image when the size of the target image included in the input image is changed;
- and
- adjusting, based on a first ratio, which is a ratio of the second size to the first size, an enlargement ratio of the projection image with respect to the input image such that the target image is displayed in the first size in the projection image.
A projector comprising:
- an optical device;
- and
- at least one processor,
- the at least one processor executing:
- receiving designation of a target image to be projected in a first size in, in an input image, a projection image obtained by the optical device projecting the input image onto a projection surface;
- calculating a second size indicating a size of the target image in the projection image when the size of the target image included in the input image is changed;
- and
- adjusting, based on a first ratio that is a ratio of the second size to the first size, an enlargement ratio of the projection image with respect to the input image such that the target image is displayed in the first size in the projection image.
A non-transitory computer-readable storage medium storing a program, the program causing a processor to execute:
- receiving designation of a target image to be projected in a first size in, in an input image, a projection image obtained by a projector projecting the input image onto a projection surface;
- calculating a second size indicating a size of the target image in the projection image when the size of the target image included in the input image is changed;
- and
- adjusting, based on a first ratio that is a ratio of the second size to the first size, an enlargement ratio of the projection image with respect to the input image such that the target image is displayed in the first size in the projection image.
