Abstract: A multimodal cranial nerve stimulation treatment system for personalized optimal rehabilitation, includes a measurement unit that measures a brain activity signal transmitted from a brain of a subject; an electrical stimulation unit that controls a brain activity of the subject by applying electrical stimulation to the brain of the subject; a haptic stimulation unit that controls the brain activity of the subject by inducing a haptic stimulation motion of the subject based on a content to be provided to the subject from a content providing unit; a detection unit that detects a brain activity region of interest requiring rehabilitation treatment by comparing the brain activity signal measured by the measurement unit with a preset reference brain activity signal; and a control unit that controls at least one of the electrical stimulation unit, the content providing unit, and the haptic stimulation unit.

Abstract: Provided are a method and apparatus for transmitting thumbnail images to an external apparatus. The method of controlling a thumbnail display, the method including connecting to an external apparatus; and in response to receiving characteristic information of the external apparatus, transmitting to the external apparatus a number of thumbnail images according to the characteristic information. The method may include providing a menu screen for a user to input the characteristic information. The method may include providing a menu screen for a user to input at least one of: a number of thumbnails to display or a size of thumbnails to display. Transmitting may include transmitting the thumbnail images sized to be inversely proportional to the number of thumbnail images so as to fit a display of the external apparatus.

Abstract: A method for operating a digital camera is provided. Particularly, the method provides for increasing image storage space by changing the resolution of a stored image when photographing a new image. The method includes: displaying images stored in the storage space on a thumbnail screen when a menu for changing a resolution is selected; selecting from the images displayed on the thumbnail screen an image whose resolution is to be changed; and changing a resolution of the selected image when the selection of the image is completed.
