Abstract

A projector apparatus capable of adjusting a projecting image without the user manually adjusting the image or selecting the past setting information for every usage opportunity. A projector apparatus according to the present invention is a projector apparatus capable of performing automatic adjustment based on past setting information related to before-use adjustment; the projector apparatus including an identification information receiving device for receiving, at an arbitrary installation location, information specific to the installation location; and a CPU for executing the automatic adjustment based on the specific information received by the identification information receiving device.

Claims

1. A projector apparatus capable of performing automatic adjustment based on past setting information related to before-use adjustment;

the projector apparatus comprising;

a receiving part for receiving, at an arbitrary installation location, information specific to the installation location; and

a controlling part for executing said automatic adjustment based on said specific information received by said receiving part.

2. The projector apparatus according to claim 1, wherein said specific information is provided from a passive tag arranged at said arbitrary installation location.

3. The projector apparatus according to claim 1, wherein said specific information includes location associated identification information associated with said installation location;

and

said projector apparatus further comprises a storage part for storing in advance said past setting information in association with said location associated identification information.

4. The projector apparatus according to claim 2, wherein

said specific information includes location associated identification information associated with said installation location;

and

said projector apparatus further comprises a storage part for storing in advance said past setting information in association with said location associated identification information,

said storage part stores said location associated identification information provided from said passive tag and the current state of said setting information in association with each other.

5. The projector apparatus according to claim 1, wherein said specific information includes said past setting information.

6. The projector apparatus according to claim 2, wherein

the specific information includes the past setting information;

and

the current state of said setting information is written to said passive tag.

7. The projector apparatus according to claim 2, further comprising a notifying part for notifying to the outside that wireless communication with said passive tag is valid/not valid according to whether or not predetermined information returned from said passive tag is received.
