The present invention relates to an electronic frame and an image displaying method of an electronic frame. The electronic frame according to one exemplary embodiment of the present invention detects, through an optical sensing unit, parts that are hidden by a frame, sets only a display area that is not hidden by the frame as a valid area, resizes an image so that the image matches the valid area of the display, and displays the image. Accordingly, even if the size of the frame is changed, a phenomenon in which a part of the image is not shown due to the frame could be prevented, as an image-resizing is adjustably performed.
