LED display device, and method for calibrating LED display device

An operating method of a video display device, and which includes obtaining an image of a user of the video display device; generating a plurality of gesture areas for the user from the obtained image; recognizing a position of a gesture object of the user from the plurality of generated gesture areas; recognizing a gesture of the user from the obtained image; and performing a control operation corresponding to the position of the recognized gesture object and the recognized gesture.

Video display device recognizing a gesture of a user to perform a control operation and operating method thereof

An image projection apparatus according to an embodiment of the present invention senses the distance to an image projection area to which an image is projected, and determines an image projection state including a state of at least one of the image projection area and a space between the image projection apparatus and the image projection area, on the basis of the sensed distance. The image projection apparatus projects an image onto the image projection area on the basis of the determined image projection state.

Image projection apparatus and operation method thereof

A method of operating the video display device according to the embodiment of the present invention comprises acquiring a video of a video display device associated with a user; recognizing a gesture of the user in the acquired video; calculating a control amount with regard to the gesture based on the recognized gesture; and performing the control operation corresponding to the recognized gesture and the calculated control amount.

Image display apparatus and operation method thereof

Provided is an operating method of a display device. The method includes: recognizing a wearable device; and providing a user interface screen of the display device differently on the basis of a wearing state of the wearable device representing whether a user wears the recognized wearable device.

Display device and operating method thereof

A method of controlling a display device, and which includes obtaining, via camera of the display device, a user's image; recognizing, via a controller of the display device, a user's hand gesture from the obtained user's image; and when the recognized user's hand gesture does not match a pre-stored gesture, displaying, via a display of the display device, a function guide including different hand gestures different than the recognized user's hand gesture for guiding a user's selection for performing a function of the display device.
