An input device with a projecting function is provided, including: a first input device and a second input device. The first input device has a first projection unit, and the second input device has a second projection unit. The first projection unit and the second projection unit are configured to execute 2D projection or 3D projection. When a projection direction of the first projection unit is the same as that of the second projection unit, the first projection unit and the second projection unit execute the 2D projection. When the projection direction of the first projection unit is perpendicular to that of the second projection unit, the first projection unit and the second projection unit execute the 3D projection. The present disclosure provides a relatively sharp 2D projected image and a function of simplifying a structure of an input device.

A three dimensional (3D) video signal is processed in a video device. The device has generating means for generating an output signal for transferring the video data via a high-speed digital interface like HDMI to a 3D display, which selectively generate a 3D display signal for displaying the 3D video data on a 3D display operative in a 3D mode, a 2D display signal for displaying 2D video data on the 3D display operative in a 2D mode, or a pseudo 2D display signal by including 2D video data in the output signal for displaying the 2D video data on the 3D display operative in the 3D mode. Processing means detects a request to display 2D video data on the 3D display, while the 3D display is operative in the 3D mode, and, in response to the detection, the generating means are set to generate the pseudo 2D display signal for maintaining the 3D mode of the 3D display.

A user interface control device provides a GUI allowing a depth of a graphic to be easily set when composing the graphic with a stereoscopic image. The device comprises: a graphic information obtaining unit that specifies an area occupied by the graphic when the graphic is arranged on one of two viewpoint images forming a stereoscopic image; a depth information analyzing unit that acquires a depth of a subject appearing within the specified area occupied by the graphic in the one viewpoint image; and a depth setting presenting unit that presents a first alternative and a second alternative for setting a depth of the graphic, the first alternative corresponding to the depth of the subject, and the second alternative corresponding to a depth differing for the depth of the subject.
