A three-dimensional image processing apparatus and a method of controlling power of same are provided. The three-dimensional image processing apparatus may include a display, a three-dimensional image filter disposed a prescribed distance from the display to adjust optical paths of the displayed view images, a camera configured to capture an image of a user, an ambient light sensor, and a controller configured to control the view images, the three-dimensional image filter, or the camera. The controller may determine a position of the user based on the captured image and adjust a perceived three-dimensional view of the view images based on the determined position of the user. Moreover, the controller may control an operational state of the camera and the at least one process based on the determined position of the user or a detected amount of ambient light.

Three-dimensional image processing apparatus and electric power control method of the same

A three-dimensional image processing apparatus and a method for controlling a location of a sweet spot for displaying a multi-view image are disclosed. A receiver receives a multi-view image including a plurality of view images. A controller detects a plurality of users from an image obtained by taking a watching zone, acquires user location information indicating locations of the plurality of detected users, calculates distance information indicating a distance between the detected users by using the acquired user location information, and controls a location of a sweet spot for viewing the plurality of view images on the basis of the calculated distance information and a length of a dead zone of the multi-view image.

Three-dimensional image processing apparatus and method for adjusting location of sweet spot for displaying multi-view image

Disclosed is a three-dimensional image display device, in particular, a three-dimensional image display device using a glassless mode. The three-dimensional image display device includes a data panel for displaying an image including a left eye image and a right eye image, a light supplier disposed at a first side of the data panel, the light supplier locally radiating light to enable a left eye image and a right eye image displayed on the data panel to be seen by a left eye and a right eye of a user, respectively, a lens array including a plurality of lenses disposed at a second side being opposite to the first side of the data panel, the lens array determining a passage such that the image supplied by the light supplier is transferred to the user, and a gap layer disposed between the data panel and the light supplier.

Three-dimensional image display device

A system, apparatus, and method for displaying a 3D image and a location tracking device are provided. A location tracking unit receives an image frame acquired by capturing an image of a user, detects a location of the user using the received image frame, calculates a movement velocity of the user using the detected location of the user and at least one of previously detected locations of the user, predicts a location of the user at time point which a predetermined time elapses using the detected location of the user and the calculated movement velocity, and calculates a 3D image change amount based on the predicted location of the user. An image processing unit performs a control operation to display a 3D image based on the calculated 3D image change amount.

System, apparatus, and method for displaying 3-dimensional image and location tracking device

An apparatus and a method of displaying 3-Dimensional image are disclosed. A camera unit serves to capture an image of a viewer. A position tracking device serves to detect a position of the viewer using a video frame included in the captured image and calculate a position of a non-transmissive region of a 3D image filter based on the detected position of the viewer. A display unit serves to move the non-transmissive region of the 3D image filter according to the calculated position of the non-transmissive region. Changing a sweet spot of the 3D image to suit movement of the viewer has the effects of enlarge a viewing angle of the viewer and preventing crosstalk and image flipping even when the viewer moves.

Apparatus and method of displaying 3-dimensional image

A three-dimensional (3D) image display device may display a perceived 3D image. A location tracking unit may determine a viewing distance from a screen to a viewer. An image processing unit may calculate a 3D image pixel period based on the determined viewing distance, may determine a color of at least one of pixels and sub-pixels displaying the 3D image based on the calculated 3D image pixel period, and may control the 3D image to be displayed based on the determined color.
