    摘要: A method and an apparatus for brightness-controlling image conversion. The method includes converting an input image of a first non-linear color space into a second linear color space; determining a brightness control ratio; adjusting channels of the second linear color space according to the brightness control ratio; converting the second linear color space into the first non-linear color space to form an output image.

    摘要: 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.
