Image display device, image display system, and method of controlling image display device

摘要

A projector capable of outputting an image to an electronic apparatus is provided, wherein the image is obtained by drawing a picture corresponding to a coordinate input from an electronic apparatus having a touch panel, or a coordinate input from an indicating body on an input image. The projector includes a video signal acquisition section adapted to obtain a first image, a first coordinate data acquisition section adapted to obtain first coordinate data from a tablet terminal having a touch panel, an image data acquisition section adapted to obtain image data representing a second image obtained by drawing a picture, which corresponds to the first coordinate data, on the first image, and an image data output section adapted to output the image data, which is obtained by the image data acquisition section, to the tablet terminal.

1. An image display device comprising:
an interface configured to obtain a video signal representing an input image; a processor configured to resize the input image to generate a first image; and a projector configured to project the first image, wherein the interface is further configured to:
obtain touch panel data representing a coordinate of a point on the first image from an electronic apparatus having a touch panel, andobtain pointing body data representing a coordinate of a point pointed by a user with a pointing body on a projection surface projected on by the projector, the processor is further configured to:
generate first coordinate data by converting the touch panel data into a coordinate system of the input image,generate second coordinate data by converting the pointing body data into the coordinate system of the input image,generate third coordinate data obtained by converting the first coordinate data and second coordinate data into a single format, andobtain image data representing a third image, which is obtained by drawing a picture corresponding to the third coordinate data on the first input image, the interface is further configured to output the image data obtained by the processor to the electronic apparatus, and the projector is further configured to project the third image.
