Abstract
A projection apparatus includes: a projection portion; and a processor, and the processor is configured to: cause a user to select, among end parts of a projection region irradiated with projection light by the projection portion, a part of an end part of the projection region; and in a state where a position of the part of the end part is sensed as being a first position, maintain the position of the part of the end part and execute, by a control of changing an optical system of the projection portion, a control of performing enlargement or reduction of the projection region.
Claims15
A projection apparatus comprising:
- a projection portion;
- and
- a processor,
- wherein the processor is configured to:
- cause a user to select, among end parts of a projection region irradiated with projection light by the projection portion, a part of an end part of the projection region;
- and
- in a state where a position of the part of the end part is sensed as being a first position, maintain the position of the part of the end part and execute, by a control of changing an optical system of the projection portion, a control of performing enlargement or reduction of the projection region.
A projection method by a projection apparatus including a projection portion, the projection method comprising:
- causing a user to select, among end parts of a projection region irradiated with projection light by the projection portion, a part of an end part of the projection region;
- and
- in a state where a position of the part of the end part is sensed as being a first position, maintaining the position of the part of the end part and performing, by a control of changing an optical system of the projection portion, enlargement or reduction of the projection region.
A non-transitory computer readable medium storing a control program of a projection apparatus including a projection portion, the control program causing a computer to execute a process comprising:
- causing a user to select, among end parts of a projection region irradiated with projection light by the projection portion, a part of an end part of the projection region;
- and
- in a state where a position of the part of the end part is sensed as being a first position, maintaining the position of the part of the end part and performing, by a control of changing an optical system of the projection portion, enlargement or reduction of the projection region.
A projection apparatus comprising:
- a projection portion;
- and
- a processor,
- wherein the processor is configured to:
- in a state where a position of a part of an end part of a projection region irradiated with projection light by the projection portion is sensed as being a first position, maintain the position of the part of the end part and execute a control of performing enlargement or reduction of the projection region;
- and
- maintain the position of the part of the end part and execute the control of performing the enlargement or reduction by performing movement of the projection region for matching the position of the part of the end part changed by the enlargement or reduction based on a center of the projection region to the first position.
A projection apparatus comprising:
- a projection portion;
- and
- a processor,
- wherein the processor is configured to:
- in a state where a position of one corner of a rectangular projection region irradiated with projection light by the projection portion is sensed as being a first position, maintain the position of the one corner and execute a control of performing enlargement or reduction of the projection region;
- and
- in a case where a position of a corner adjacent to the one corner among corners of the projection region is sensed as being a second position in a state where an aspect ratio of the projection region is maintained and the enlargement or reduction is performed, maintain each position of the one corner and the adjacent corner and execute the control of performing the enlargement or reduction of the projection region.
A projection method by a projection apparatus including a projection portion, the projection method comprising:
- in a state where a position of a part of an end part of a projection region irradiated with projection light by the projection portion is sensed as being a first position, maintaining the position of the part of the end part and performing enlargement or reduction of the projection region,
- wherein the position of the part of the end part is maintained and the enlargement or reduction is performed by performing movement of the projection region for matching the position of the part of the end part changed by the enlargement or reduction based on a center of the projection region to the first position.
A projection method by a projection apparatus including a projection portion, the projection method comprising:
- in a state where a position of one corner of a rectangular projection region irradiated with projection light by the projection portion is sensed as being a first position, maintaining the position of the one corner and performing enlargement or reduction of the projection region,
- wherein in a case where a position of a corner adjacent to the one corner among corners of the projection region is sensed as being a second position in a state where an aspect ratio of the projection region is maintained and the enlargement or reduction is performed, each position of the one corner and the adjacent corner is maintained and the enlargement or reduction of the projection region is performed.
A non-transitory computer readable medium storing a control program of a projection apparatus including a projection portion, the control program causing a computer to execute a process comprising:
- in a state where a position of a part of an end part of a projection region irradiated with projection light by the projection portion is sensed as being a first position, maintaining the position of the part of the end part and performing enlargement or reduction of the projection region,
- wherein the position of the part of the end part is maintained and the enlargement or reduction is performed by performing movement of the projection region for matching the position of the part of the end part changed by the enlargement or reduction based on a center of the projection region to the first position.
A non-transitory computer readable medium storing a control program of a projection apparatus including a projection portion, the control program causing a computer to execute a process comprising:
- in a state where a position of one corner of a rectangular projection region irradiated with projection light by the projection portion is sensed as being a first position, maintaining the position of the one corner and performing enlargement or reduction of the projection region,
- wherein in a case where a position of a corner adjacent to the one corner among corners of the projection region is sensed as being a second position in a state where an aspect ratio of the projection region is maintained and the enlargement or reduction is performed, each position of the one corner and the adjacent corner is maintained and the enlargement or reduction of the projection region is performed.
