1. An input user interface device comprising:
- an electronic camera which captures an image including an object image;
a shape detection unit which detects a shape of the object image in the image captured by the electronic camera;
a determination unit which determines whether a single shape of the object image detected by the shape detection unit corresponds to a shape associated with a gesture command or a shape associated with a position designation command for designating a position;
a position detection unit which detects a position of the object image in each of a plurality of frames of the image captured by the electronic camera;
a gesture detection unit which detects a gesture of the object image in the image based on sequentially detected positions of the object image in the plurality of frames detected by the position detection unit; and
a controller which decides whether a single input corresponds to (i) the gesture command, based on the determination by the determination unit with respect to the single shape, data obtained via the position detection unit, and data obtained via the gesture detection unit, or (ii) the position designation command, based on the determination by the determination unit with respect to the single shape,wherein the controller does not use the data obtained by the gesture detection unit when deciding whether the single input corresponds to the position designation command.

Abstract
An input user interface device includes an image pickup unit which picks up an image including an object image, a shape detection unit which detects a shape of the object image in the image picked up by the image pickup unit, a determination unit which determines whether the shape of the object image detected by the shape detection unit corresponds to a shape associated with a gesture command or a shape associated with a position designation command for designating a position data, and a command deciding unit which decides the gesture command or the position designation command on the basis of the decision by the deciding unit.

1. An input user interface device comprising:
-
an electronic camera which captures an image including an object image; a shape detection unit which detects a shape of the object image in the image captured by the electronic camera; a determination unit which determines whether a single shape of the object image detected by the shape detection unit corresponds to a shape associated with a gesture command or a shape associated with a position designation command for designating a position; a position detection unit which detects a position of the object image in each of a plurality of frames of the image captured by the electronic camera; a gesture detection unit which detects a gesture of the object image in the image based on sequentially detected positions of the object image in the plurality of frames detected by the position detection unit; and a controller which decides whether a single input corresponds to (i) the gesture command, based on the determination by the determination unit with respect to the single shape, data obtained via the position detection unit, and data obtained via the gesture detection unit, or (ii) the position designation command, based on the determination by the determination unit with respect to the single shape, wherein the controller does not use the data obtained by the gesture detection unit when deciding whether the single input corresponds to the position designation command. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9)

10. A projecting device, comprising:
-
an input user interface device comprising; an electronic camera which captures an image including an object image; a shape detection unit which detects a shape of the object image in the image captured by the electronic camera; a determination unit which determines whether a single shape of the object image detected by the shape detection unit corresponds to a shape associated with a gesture command or a shape associated with a position designation command for designating a position; a position detection unit which detects a position of the object image in each of a plurality of frames of the image captured by the electronic camera; a gesture detection unit which detects a gesture of the object image in the image based on sequentially detected positions of the object image in the plurality of frames detected by the position detection unit; and a controller which decides whether a single input corresponds to (i) the gesture command, based on the determination by the determination unit with respect to the single shape, data obtained via the position detection unit, and data obtained via the gesture detection unit, or (ii) the position designation command, based on the determination by the determination unit with respect to the single shape, wherein the controller does not use the data obtained by the gesture detection unit when deciding whether the single input corresponds to the position designation command; and a projecting device body which receives a video signal from an external device and projects image data represented by the received video signal, wherein the input of the gesture command decided by the controller is a control command for the projecting device body. - View Dependent Claims (11)

12. A method for deciding a command, the method comprising:
-
capturing an image including an object image using an electronic camera; detecting a shape of the object image in the image captured in the capturing; determining whether a single shape detected in the detecting corresponds to a shape associated with a gesture command or a shape associated with a position designation command for designating a position; detecting a position of the object image in each of a plurality of frames of the image captured in the capturing; detecting a gesture of the object image in the image based on sequentially detected positions of the object image in the plurality of frames; and deciding, by a controller, whether a single input corresponds to (i) the gesture command, based on the determination with respect to the single shape, data obtained via the detecting the position of the object image, and data obtained via the detecting the gesture of the object image, or (ii) the position designation command based on the determination with respect to the single shape, wherein the deciding whether the single input corresponds to the position designation command is not based on the data obtained via the detecting the gesture of the object image.

13. A non-transitory computer readable recording medium having a program stored thereon to control a computer to execute a procedure, the computer receiving an image input from an electronic camera which captures an image including an object image, and the procedure comprising:
-
capturing an image including an object image; detecting a shape of the object image in the image captured by the electronic camera; determining whether a single shape of the object image detected by the shape detection unit corresponds to a shape associated with a gesture command or a shape associated with a position designation command for designating a position; detecting a position of the object image in each of a plurality of frames of the image captured by the electronic camera; detecting a gesture of the object image in the image based on sequentially detected positions of the object image in the plurality of frames; and deciding, by a controller, whether a single input corresponds to (i) the gesture command, based on the determination with respect to the single shape, data obtained via the detecting the position of the object image, and data obtained via the detecting the gesture of the object image, or (ii) the position designation command based on the determination with respect to the single shape, wherein the deciding, by the controller, whether the single input corresponds to the position designation command is not based on the data obtained via the detecting the gesture of the object image.
