Abstract
An auxiliary apparatus for a projection apparatus used in association with a projection apparatus for projecting an optical image, includes: a communication device that performs communication with the projection apparatus; and a projection auxiliary control device that, when communication is performed with the projection apparatus through the communication device, expands a projection function of the projection apparatus broader than when the optical image is projected without the communication.
Claims11
An auxiliary apparatus for a projection apparatus used in association with a projection apparatus for projecting an optical image, comprising:
- a communication device that performs communication with the projection apparatus;
- and
- a projection auxiliary control device that, when communication is performed with the projection apparatus through the communication device, expands a projection function of the projection apparatus broader than when the optical image is projected without the communication.
A projection system, comprising:
- a projection apparatus;
- and
- an auxiliary apparatus for the projection apparatus used in association with the projection apparatus, wherein:
- the projection apparatus comprises a projection section that projects an optical image, a first communication device that performs communication with the auxiliary apparatus for the projection apparatus, and a projection control device that, when communication is performed with the auxiliary apparatus for the projection apparatus through the first communication device, expands a projection function of the projection section broader than when the optical image is projected without the communication, and
- the auxiliary apparatus for the projection apparatus comprises a second communication device that performs communication with the projection apparatus, and a projection auxiliary control device that, when communication is performed with the projection apparatus through the second communication device, expands a projection function of the projection section broader than when the optical image is projected without the communication.
A projection assisting method for assisting a projection operation of a projection apparatus that projects an optical image by using an auxiliary apparatus for a projection apparatus in association with the projection apparatus, comprising:
- performing communication between the projection apparatus and the auxiliary apparatus for the projection apparatus;
- and
- expanding a projection function of the projection apparatus when the communication is performed between the projection apparatus and the auxiliary apparatus for the projection apparatus broader than when the optical image is projected without performing the communication.
