Abstract
A projection method includes detecting a first distance between a projector and a first portion of a projection surface, detecting a second distance between the projector and a second portion of the projection surface, detecting a third distance between the projector and a third portion of the projection surface, projecting image light in a first visual aspect according to the first distance onto the first portion by using the projector, projecting image light in a second visual aspect according to the second distance onto the second portion by using the projector, and projecting image light in a third visual aspect based on the first and second visual aspects onto the third portion by using the projector when the third distance is longer than the first distance but shorter than the second distance.

A projection method comprising:
- detecting a first distance between a projector and a first portion of a projection surface;
- detecting a second distance between the projector and a second portion of the projection surface;
- detecting a third distance between the projector and a third portion of the projection surface;
- projecting image light in a first visual aspect according to the first distance onto the first portion by using the projector;
- projecting image light in a second visual aspect according to the second distance onto the second portion by using the projector;
- projecting image light in a third visual aspect based on the first and second visual aspects onto the third portion by using the projector when the third distance is longer than the first distance but shorter than the second distance;
- and
- displaying a user interface for accepting input of information that specifies at least one of the first and second visual aspects, wherein:
- the first distance is a distance between the first portion and a planar plane perpendicular to a projection axis of the projector,
- the second distance is a distance between the second portion and the planar plane,
- the projection axis is a center axis of a projection range of the projector,
- the first visual aspect is a first color, the second visual aspect is a second color that is different from the first color, and the third visual aspect is an intermediate color between the first color and the second color, and
- the user interface accepts the input of the information from a user.
A projector comprising:
- a light source;
- a light modulator that modulates light outputted from the light source;
- a distance sensor;
- and
- at least one processor configured to
- detect a first distance between the projector and a first portion of a projection surface by using the distance sensor,

- project image light in a first visual aspect according to the first distance onto the first portion by using the light source and the light modulator,
- project image light in a second visual aspect according to the second distance onto the second portion by using the light source and the light modulator,
- project image light in a third visual aspect based on the first and second visual aspects onto the third portion by using the light source and the light modulator when the third distance is longer than the first distance but shorter than the second distance, and
- display a user interface for accepting input of information that specifies at least one of the first and second visual aspects, wherein:
- the first distance is a distance between the first portion and a planar plane perpendicular to a projection axis of the projector,
- the second distance is a distance between the second portion and the planar plane,
- the projection axis is a center axis of a projection range of the projector,
- the first visual aspect is a first color, the second visual aspect is a second color that is different from the first color, and the third visual aspect is an intermediate color between the first color and the second color, and
