Abstract: A method comprising: obtaining at least one of a first current amount or a first pulse width that correspond to a first luminance level; obtaining at least one of a second current amount or a second pulse width that correspond a second luminance level; detecting at least one of a difference between the first current amount and the second current amount or a difference between the first pulse width and the second pulse width; and generating, by an electronic device, a new luminance level based on at least one of the difference between the first current amount and the second current amount or the difference between the first pulse width and the second pulse width, wherein the new luminance level is higher than the first luminance level and lower than the second luminance level.

Abstract: A display control method of an electronic device is provided. The display control method includes sensing, by the electronic device, a chromaticity and an illuminance of an incident light, calculating an optimal white of a display based on the chromaticity of the incident light, and correcting the calculated optimal white by using the illuminance of the incident light.

Abstract: Various examples of the present invention provide an electronic device comprising: a display for displaying content in a direction corresponding to a first surface of the electronic device; a sensor for sensing light incident on a second surface of the electronic device; and a processor, wherein the processor determines information of the brightness around the electronic device, at least on the basis of the sensed light, and can be set to adjust at least one attribute of the display or at least one attribute of the content. In addition, other examples besides the various examples of the present invention are possible.

Abstract: 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.

Abstract: 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.

Abstract: 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.
