Abstract
A projector includes an optical device and a processing device. The processing device executes projecting a projection image including a first image onto a projection surface using the optical device, acquiring a first value relating to a first length of the first image on the projection surface, and outputting, based on the first value, information indicating a third value corresponding to a second length of the projection image projected onto the projection surface, the second length being a value at the time when the first length on the projection surface is adjusted to a second value.
Claims20
A projector comprising:
- an optical device;
- and
- a processing device,
- the processing device executing:
- projecting a projection image including a first image onto a projection surface using the optical device;
- acquiring a first value relating to a first length of the first image on the projection surface;
- outputting, based on the first value, information indicating a third value corresponding to a second length of the projection image projected onto the projection surface, the second length being a value at a time when the first length on the projection surface is adjusted to a second value;
- and
- wherein:
- the processing device receives, via an input device, first operation for enlarging or reducing the first image, and
- the outputting the information indicating the third value is outputting, based on the first value and an operation amount of the first operation until the second length is adjusted to the second value, the information indicating the third value.
A control method for a projector comprising:
- projecting a projection image including a first image onto a projection surface;
- acquiring a first value relating to a first length of the first image on the projection surface;
- outputting, based on the first value, information indicating a third value corresponding to a second length of the projection image projected onto the projection surface, the second length being a value at a time when the first length on the projection surface is adjusted to a second value;
- and
- receiving, via an input device, a first operation for enlarging or reducing the first image;
- wherein the outputting the information indicating the third value is outputting, based on the first value and an operation amount of the first operation until the second length is adjusted to the second value, the information indicating the third value.
A non-transitory computer-readable storage medium storing a program, the program causing a projector to execute:
- projecting a projection image including a first image onto a projection surface;
- acquiring a first value relating to a first length of the first image on the projection surface;
- outputting, based on the first value, information indicating a third value corresponding to a second length of the projection image projected onto the projection surface, the second length being a value at a time when the first length on the projection surface is adjusted to a second value;
- and
- receiving, via an input device, a first operation for enlarging or reducing the first image;
- wherein the outputting the information indicating the third value is outputting, based on the first value and an operation amount of the first operation until the second length is adjusted to the second value, the information indicating the third value.
