  • Patent number: 9064319
    Abstract: An image processing apparatus including a region of interest (ROI) configuration unit may generate a visual attention map according to visual characteristics of a human in relation to an input three dimensional (3D) image. A disparity adjustment unit may adjust disparity information, included in the input 3D image, using the visual attention map. Using the disparity information adjusted result, a 3D image may be generated and displayed which reduces a level of visual fatigue a user may experience in viewing the 3D image.

  • Patent number: 8605105
    Abstract: An image processing apparatus and a method for enhancing depth are disclosed. The image processing apparatus may classify an input image into a foreground layer, a middle layer, a background layer, may calculate a representative color of each of the classified layers, and perform rendering of a color stereoscopy of the middle layer and a color stereoscopy of the background layer based on the representative color and a lightness of the background layer, thereby enhancing a stereoscopic effect and a depth. Also, a color temperature of the foreground layer and a color temperature of the middle layer are controlled based on the representative color and the background layer, to generate a difference in depth between the middle layer and the foreground layer, thereby representing an image having a more enhanced depth.
