Abstract
A control apparatus that controls a projection area of each of projection devices is provided. The control apparatus notifies relating to control of the projection areas, in a case where a temperature variation of at least one projection device, among the projection devices, is greater than or equal to a threshold value.
Claims17
A control apparatus that controls a projection area of each of projection devices, wherein the control apparatus includes at least one or more processors and/or at least one or more electronic circuits configured to execute operations of each of the following units:
- a control unit configured to control the projection area of each of the projection devices;
- and
- a notification unit configured to perform notification relating to control of the projection areas, in a case where a temperature variation of at least one projection device, among the projection devices, is greater than or equal to a threshold value.
A projection device for projecting an image onto a projection area, comprising:
- at least one or more processors and/or at least one or more electronic circuits that perform operations of each of the following units:
- a control unit configured to control a shape or a position of the projection area;
- a determination unit configured to determine whether a temperature variation of the projection device satisfies a predetermined condition;
- and
- a notification unit configured to perform predetermined notification relating to control of the projection area, in a case where the determination unit determines that the temperature variation of the projection device does not satisfy the predetermined condition.
A projection system comprising a plurality of projection devices and a control apparatus configured to control a projection area of each of projection devices,
- wherein the control apparatus includes at least one or more processors and/or at least one or more electronic circuits that execute operations of each of the following units:
- a control unit configured to control the projection area of each of the projection devices;
- and
- a notification unit configured to perform notification relating to control of the projection areas, in a case where a temperature variation of at least one projection device, among the projection devices, is greater than or equal to a threshold value.
A control method for a control apparatus that controls a projection area of each of projection devices, the method comprising:
- controlling the projection area of each of the projection devices;
- and
- performing notification relating to control of the projection areas, in a case where a temperature variation of at least one projection device, among the projection devices, is greater than or equal to a threshold value.
A control method for a projection device that projects an image onto a projection area, the method comprising:
- controlling a shape or a position of the projection area;
- determining whether a temperature variation of the projection device satisfies a predetermined condition;
- and
- performs predetermined notification relating to control of the projection area in the controlling, in a case where it is determined in the determining that the temperature variation of the projection device does not satisfy the predetermined condition.
A non-transitory computer-readable storage medium that stores a program, wherein the program, when executed by at least one processor of a control apparatus that controls a projection area of each of projection devices, causes the at least one processor as:
- a control unit configured to control the projection area of each of the projection devices;
- and
- a notification unit configured to perform notification relating to control of the projection areas, in a case where a temperature variation of at least one projection device, among the projection devices, is greater than or equal to a threshold value.
A non-transitory computer-readable storage medium that stores a program, wherein the program, when executed by at least one processor of a projection device for projecting an image onto a projection area, causes the at least one processor as:
- a control unit configured to control a shape or a position of the projection area;
- a determination unit configured to determine whether a temperature variation of the projection device satisfies a predetermined condition;
- and
- a notification unit configured to perform predetermined notification relating to control of the projection area, in a case where the determination unit determines that the temperature variation of the projection device does not satisfy the predetermined condition.
