Patent application number | Description | Published |
20110069068 | Image processing apparatus and method - Provided is an image processing apparatus and process. The image processing apparatus may perform three-dimensional (3D) rendering by adaptively providing virtual point lights (VPLs). It is possible to adaptively adjust an amount of 3D rendering calculations according to a desired quality, and to provide a real-time rendering result for each calculation process. | 03-24-2011 |
20120007865 | Image processing apparatus and method - Provided is an image processing apparatus. A bidirectional reflection distribution function (BRDF) summed area table (SAT) generator of the image processing apparatus may generate a BRDF SAT of a first point using a BRDF of the first point within a three-dimensional (3D) model. A virtual area light (VAL) sampling unit of the image processing apparatus may sample a VAL corresponding to at least one point on an object of the 3D model. | 01-12-2012 |
20120113097 | Display apparatus and method - A display apparatus that may generate a high density light field image is provided. The display apparatus may identify an eye position of a user and set a virtual viewing window around the eye of the user. The display apparatus may generate a directional light corresponding to the viewing window and generate a high density light field image. | 05-10-2012 |
20120299922 | IMAGE PROCESSING APPARATUS AND METHOD - Provided is an image processing apparatus. The image processing apparatus may adaptively sample a virtual point light (VPL) at a light view within a three-dimensional (3D) model. The image processing apparatus may adaptively sample a surface point at a camera view. | 11-29-2012 |
20120320039 | APPARATUS AND METHOD FOR IMAGE PROCESSING - Image processing apparatus and method. A modeling unit may generate a three-dimensional (3D) model corresponding to an actual object from an input color image and an input depth image corresponding to the input color image. A calculator may perform photon-based rendering with respect to an input virtual object and the 3D model based on input light environment information, and may generate a difference image comprising color distortion information occurring by inserting the virtual object into the 3D model. A rendering unit may generate a result image comprising the virtual object by synthesizing the difference image and the input color image. | 12-20-2012 |
20130002694 | IMAGE PROCESSING APPARATUS AND METHOD - An image processing apparatus. The image processing apparatus may perform filtering to emphasize a surface lighting of a low frequency band from an input lighting environment image, and may also perform at least one virtual point light (VPL) sampling from the input lighting environment image. The image processing apparatus may perform precomputed radiance transfer (PRT) based rendering using the filtered lighting environment image and VPL based rendering using the sampled VPL. | 01-03-2013 |
