Provided are a method and a device for processing image data. According to the method, first characteristic values respectively of a plurality of regions of a first image are determined by sequentially calculating, for each of the plurality of regions, characteristic values corresponding to each of pixel values of pixels included in each of the plurality of regions while sequentially receiving the pixel values of the pixels; based on the determined first characteristic values, an illumination image related to a second image that is a following image of the first image is obtained; and, based on the obtained illumination image, the second image is modified.

A user interface apparatus and method in a user terminal that uses a capacitive touch input scheme are provided. The method includes monitoring an input signal that is generated by a touch on a touch panel; and in response to detecting an input signal generated by the touch, determining an area of the touch based on the input signal, and differently processing a selected command depending on the determined area.

A display method and a display device for optimizing screen brightness of a mobile terminal are provided. The display method includes: determining an external illuminance value based on a sensor signal by detecting by the sensor signal for determining a brightness value of a screen; determining the brightness value of the screen corresponding to the external illuminance value; and outputting an image signal by using the brightness value of the screen.

An apparatus and method are provided for performing detail enhancement. The apparatus includes an edge detector that detects an edge pixel from contents based on a luminance component of the contents, a histogram analyzer that generates at least one histogram with respect to the edge pixel and determines a gain variable value of the edge pixel based on the at least one histogram, and a gain regulator that determines a gain corresponding to the gain variable value of the edge pixel.

A method and apparatus are provided for enhancing the readability of a character. The method includes determining ambient light of a mobile terminal and controlling background color and character color of a character image according to the determined ambient light. The method may further include performing an additional control according to the types of displays when controlling the background color and character color. Through this, it is possible to display a character image with enhanced visibility, while minimizing current consumption.

Apparatus and method for configuring a screen for a video call using a facial expression by recognizing a face from an image, calculating facial expression information for an expression of the recognized face, and determining whether there is a change in expression of the recognized face by comparing the calculated facial expression information with reference expression information preset to determine a change in expression of the face. If there is a change in expression of the recognized face, the apparatus and method selects a video image corresponding to the changed expression in the video call screen, and reconfigures the video call screen using the selected video image, making it possible for a user to conveniently select an image of the interested person without taking extensive action, and preventing a wrong image from being selected due to the unintended user facial movement.

A method is provided for searching a route of a mobile node in a short-range communication environment. A first router to which a mobile node belongs acquires a unique address of the mobile node for communication with the mobile node. The first router determines whether the mobile node travels during communication. When the mobile node travels, the first router broadcasts the unique address of the mobile node to one or more neighboring routers and determines whether the one or more neighboring routers include the mobile node. If a second router, which is one of the one or more neighboring routers, includes the mobile node, the second router performs communication using the unique address without an additional address acquisition process.
