Provided is a method, performed by a device, of processing an image, the method including tracking a movement of a user wearing the device and generating movement information of the user, the movement information being about a movement occurring between a previous time when a first image was rendered and a current time when a second image is rendered; selecting at least one pixel from among a plurality of pixels comprised in the first image, based on the generated movement information and a location of a target pixel comprised in the second image; and changing a value of the target pixel by blending a value of the selected at least one pixel with the value of the target pixel according to a preset weight.

Method and device for processing image, and recording medium

A display device is provided. The display device includes: a graphic processing unit rendering strokes; a display displaying an image including the rendered strokes; and a processor identifying a redraw region when a redraw event occurs on the image, and providing rendering information for rendering strokes included in the redraw region to the graphic processing unit, wherein the graphic processing unit renders the strokes included in the redraw region using point primitives on the basis of the rendering information.

Display device and method of controlling display device

Provided are an image processing apparatus and method for decreasing an amount of power consumed to display an image. The image processing apparatus includes: an input interface configured to input image data; at least one processor configured to obtain an output pixel value by adjusting at least one selected from luminance, resolution, and precision regarding a portion of the image data; and an output interface configured to output image data including the obtained output pixel value.

Image processing method and apparatus for operating in low-power mode

A method of processing a graphics command may include: receiving the graphics command from an apparatus that executes an application; selecting at least one shader included in the graphics command to be processed by a graphics processor; creating a shader program using the selected at least one shader; searching for a shader program corresponding to the created shader program from among one or more previously compiled shader programs; and outputting a found shader program.

Method and apparatus for efficient processing of graphics commands

A shadow rendering method is provided. The shadow rendering method includes emitting radial light to an object so that a shadow area for the object generated by a three-dimensional modeling is projected; determining a portion of the shadow area as a penumbra area for the object; and rendering a penumbra for the object to the penumbra area.

Shadow rendering apparatus and control method thereof

A photographing method, medium, and apparatus based on face detection in a portable camera. The portable photographing apparatus may include an image input unit that receives an image, a face detection unit that detects a face from the received image, a storage unit that stores the image detected by the face detection unit as a moving image in a first mode, and a quality evaluation unit that evaluates the quality of the image detected by the face detection unit and stores the same as a still image in a second mode upon satisfaction of predetermined conditions evaluated based on the quality evaluation of the still image.

Apparatus, medium, and method for photographing based on face detection

A method, medium, and system efficiently rendering 3 dimensional (3D) graphics data. The rendering method includes calculating the strength of a fog effect that is to be applied to graphics data, determining whether texture mapping must be performed on the graphics data, according to the strength of the fog effect, and performing the texture mapping according to the determination result. Accordingly, it is possible to reduce the number of memory access operations for reading textures.

Method, medium, and system rendering 3 dimensional graphics data considering fog effect

An apparatus for and method of processing a vertex in relation to 3 dimensional (3D) graphics pipeline are provided. According to the method, while a processor processes vertex data in units of batches, vertex data corresponding to a batch to be processed next is extracted and temporarily stored in a buffer independently of the processor. If the processor finishes processing of the current batch, the batch stored in the buffer is output so that the processor can immediately process the batch.

Apparatus for and method of processing vertex

Provided are a method and apparatus for avoiding bank conflict. A first instruction that is one of access instructions that are predicted to cause the bank conflict is replaced with a second instruction by changing an execute timing of the first instruction to a timing prior to the execute timing of the first instruction so as for the access instructions not to cause the bank conflict. Next, a load/store unit that is scheduled to access the bank according to the first instruction accesses the bank and reads out a data from the bank at an execute timing of the second instruction, and after that, the load/store unit is allowed to be inputted the read data at the execute timing of the first instruction. Accordingly, although the access instructions that are predicted to cause the bank conflict are allocated to the load/store units, the bank conflict can be prevented, so that it is possible to avoid deterioration in performance due the occurrence of the bank conflict.

Apparatus and method of avoiding bank conflict in single-port multi-bank memory system

According to the present invention, a service is configured by a plurality of sessions and respective session negotiation requests defined by different media formats can be performed without influencing existing connected sessions, and hence it is easy to add, delete, and change the media, the contact of session negotiation can be specified, and the response to the session negotiation request can be processed easily with the service acceptance or rejection of the contact.

Terminal unit for handling session on the basis of session initiation protocol, method of transmitting and receiving thereof

Provided is a method and of controlling a voltage of power supplied to a 3-dimensional (3D) graphics data processor and the 3D graphics data processor using the method. The method includes controlling the voltage of the power supplied to the graphics data processor based on the amount of data representing an object included in graphics data and re-controlling the voltage of the power supplied to the graphics data processor based on a time difference between scheduled processing time according to the controlled voltage for the object and actual processing time consumed by the graphics data processor, thereby reducing power consumption.

Method of controlling voltage of power supplied to 3D graphics data processor and the 3D graphics data processor using the method

There are provided a system and method for providing information using a spoken dialogue interface. The system includes a speech recognizer for transforming voice signals into sentences; a sentence analyzer for analyzing the sentences by their structural elements; a dialogue manager for extracting information on speech acts or intentions from the structural elements, and generating information on system's speech acts or intentions for a response to the extracted information on speech acts or intentions; a sentence generator for generating sentences based on the information on the system's speech acts or intentions for the response; a speech synthesizer for synthesizing the generated sentences into voices; an information extractor for extracting information required for the response from the Internet in real time; and a user modeling means for analyzing and classifying users' tendencies. Information demanded by a user can be detected in real time and provided through a voice interface with versatile and familiar dialogues based on the user's tendencies.
