Image information projection device and projection device control method
First Claim
1. An image information projection device comprising:
- a main body;
a projector configured to project image information onto at least two screens having different separation distances from the main body;
a sensor configured to sense separation distances between the at least two screens and the main body; and
a controller coupled to the projector and the sensor, the controller configured to control the projector such that different image information is projected onto the at least two screens based on the separation distances between the at least two screens and the main body,wherein the controller projects image information corresponding to content selected by a user onto a first screen among the at least two screens, and projects image information related to the content onto a second screen among the at least two screens,wherein the controller is further configured to;
determine the image information display areas on the at least two screens, based on points where the separation distances are changed on image information display regions on the at least two screens; and
sort the at least two screens into the first screen and the second screen based on at least one of the separation distances and image information display areas on the at least two screens, andwherein the controller determines a screen having a largest image information display area as the first screen.

Abstract
The present invention relates to a device for projecting image information and a control method for the device, the device comprising: a main body; a projection unit for projecting image information onto at least two screens having different separation distances from the main body; a detection unit for detecting separation distances between each of the at least two screens and the main body; and a control unit for controlling the projection unit such that different pieces of image information are projected onto the screens on the basis of the separation distances between the main body and the screens, wherein the control unit projects image information corresponding to content selected by a user onto a first screen among the screens and projects image information related to the content onto a second screen.

18. A method for controlling an image information projection device, the method including:
-
sensing, via a sensor, separation distances between a main body of the image information projection device and at least two screens having different separation distances from the main body; sorting the at least two screens into a first screen onto which image information corresponding to content selected by a user is projected, and a second screen onto which image information related to the content is projected; and projecting, via a projector, the image information corresponding to the content, and the image information related to the content, onto the sorted screens, wherein the sorting the screens further comprises; determining, via a controller, the image information display areas on the at least two screens, based on points where the separation distances are changed on image information display regions on the at least two screens; and sorting the at least two screens into the first screen and the second screen based on at least one of the separation distances and image information display areas on the at least two screens, and wherein a screen having the largest image information display area is determined as the first screen.
