Abstract
An image projection apparatus communicable with another image projection apparatus and having a first internal time includes a time acquirer configured to acquire information of a second internal time included in the other image projection apparatus through a communication, and a controller configured to calculate a difference between the first internal time and the second internal time and to set, using the difference, an operation time for implementing a first operation and a second operation for an adjustment relating to an image projection by the image projection apparatus and the other image projection apparatus.
Claims12
An image projection apparatus communicable with another image projection apparatus and having a first internal time, the image projection apparatus comprising:
- a time acquirer configured to acquire information of a second internal time included in the other image projection apparatus through a communication;
- and
- a controller configured to calculate a difference between the first internal time and the second internal time and to set, using the difference, an operation time for implementing a first operation and a second operation for an adjustment relating to an image projection by the image projection apparatus and the other image projection apparatus.
A method of controlling an image projection apparatus communicable with another image projection apparatus and having a first internal time, the method comprising the steps of:
- acquiring information of a second internal time included in the other image projection apparatus through a communication;
- and
- calculating a difference between the first internal time and the second internal time and to set, using the difference, an operation time for implementing a first operation and a second operation for an adjustment relating to an image projection by the image projection apparatus and the other image projection apparatus.
An image projection apparatus communicable with another image projection apparatus and having a first internal time, the image projection apparatus comprising:
- a time acquirer configured to acquire information of a second internal time included in the other image projection apparatus through a communication;
- and
- a timing controller configured to calculate a difference between the first internal time and the second internal time and to perform, using the difference, an operation such that the image projection apparatus and the other image projection apparatus have synchronized image projection timings.
A method of controlling an image projection apparatus communicable with another image projection apparatus and has a first internal time, the method comprising the steps of:
- acquiring information of a second internal time included in the other image projection apparatus through a communication;
- and
- calculating a difference between the first internal time and the second internal time and to perform, using the difference, an operation such that the image projection apparatus and the other image projection apparatus have synchronized image projection timings.
A non-transitory computer-readable storage medium storing a computer program for causing a computer of an image projection apparatus communicable with another image projection apparatus and having a first internal time, to execute processing according to a control method,
- wherein the control method comprises the steps of:
- acquiring information of a second internal time included in the other image projection apparatus through a communication;
- and
- calculating a difference between the first internal time and the second internal time and to set, using the difference, an operation time for implementing a first operation and a second operation for an adjustment relating to an image projection by the image projection apparatus and the other image projection apparatus.
A non-transitory computer-readable storage medium storing a computer program for causing a computer of an image projection apparatus communicable with another image projection apparatus and having a first internal time, to execute processing according to a control method,
- wherein the control method comprises the steps of:
- acquiring information of a second internal time included in the other image projection apparatus through a communication;
- and
- calculating a difference between the first internal time and the second internal time and to perform, using the difference, an operation such that the image projection apparatus and the other image projection apparatus have synchronized image projection timings.
