The method includes detecting face motion from an image captured through a camera of the electronic device and executing a control service corresponding to the detected face motion information. ## Claims ### Claim 1 A method in an electronic device, the method comprising: detecting face motion from at least one of image captured through at least one of camera of the electronic device; and executing a control service corresponding to the detected face motion information. ### Claim 2 (depends on 1) The method of claim 1, wherein the face motion information includes at least one of a face motion distance, a face direction, a face motion speed, a face motion angle, and a face motion time. ### Claim 3 (depends on 1) The method of claim 1, wherein the detection of the face motion comprises: determining at least one reference face among a plurality of faces when the plurality of faces is detected on the image captured through the camera; and detecting motion of the at least one reference face. ### Claim 4 (depends on 1) The method of claim 1, wherein the execution of the control service comprises: pausing video play in response to a face angle change when a face motion angle moves out of a reference range while a video is reproduced. ### Claim 5 (depends on 1) The method of claim 1, wherein the execution of the control service comprises: pausing video play in response to a face angle change when a face motion angle moves out of a reference range during a reference time while a video is reproduced. ### Claim 6 (depends on 1) The method of claim 1, wherein the execution of the control service comprises: scrolling a screen in response to a position change direction of eyes from the image when positions of the eyes according to the face motion information move out of a reference point. ### Claim 7 (depends on 6) The method of claim 6, wherein the scrolling of the screen comprises: determining a screen scroll direction based on the position change direction of the eyes; determining a scroll speed based on at least one of a face motion speed and a face motion angle; and scrolling the screen based on the screen scroll direction and the scroll speed. ### Claim 8 (depends on 1) The method of claim 1, wherein the execution of the control service comprises: determining whether to receive a call based on a call receiving method corresponding to a face motion direction when receiving the call, wherein the call receiving method includes at least one of call receiving acceptance, voice mail box connection, and call receiving rejection. ### Claim 9 (depends on 1) The method of claim 1, wherein the execution of the control service comprises: verifying positions of eyes from the image based on face motion information when e-book contents are displayed; and changing pages when the eyes gaze at a first region. ### Claim 10 (depends on 1) The method of claim 1, wherein the execution of the control service comprises: changing pages based on a face motion direction when e-book contents are displayed. ### Claim 11 An electronic device comprising: at least one camera; a display unit; and at least one processor, wherein at least the one processor is configured to detect face motion from at least one image captured through the at least one camera of the electronic device, and to execute a control service corresponding to the detected face motion information. ### Claim 12 (depends on 11) The electronic device of claim 11, wherein the face motion information includes at least one of a face motion distance, a face direction, a face motion speed, a face motion angle, and a face motion time. ### Claim 13 (depends on 11) The electronic device of claim 11, wherein the at least the one processor is further configured to determine at least one reference face among a plurality of faces when the plurality of faces is detected on the image captured through at least the one camera, and to detect motion of the at least one reference face. ### Claim 14 (depends on 11) The electronic device of claim 11, wherein the at least the one processor is further configured to pause video play in response to a face angle change when a face motion angle moves out of a reference range while a video is reproduced. ### Claim 15 (depends on 11) The electronic device of claim 11, wherein the at least the one processor is further configured to pause video play in response to a face angle change when a face motion angle moves out of a reference range during a reference time while a video is reproduced. ### Claim 16 (depends on 11) The electronic device of claim 11, wherein the at least the one processor is further configured to scroll a screen in response to a position change direction of eyes from the image when positions of the eyes according to the face motion information move out of a reference point. ### Claim 17 (depends on 16) The electronic device of claim 16, wherein the at least the one processor is further configured to determine a screen scroll direction based on the position change direction of the eyes, to determine a scroll speed based on at least one of a face motion speed and a face motion angle, and to scroll the screen based on the screen scroll direction and the scroll speed. ### Claim 18 (depends on 11) The electronic device of claim 11, wherein the at least the one processor is further configured to determine whether to receive a call based on a call receiving method corresponding to a face motion direction when receiving the call, and wherein the call receiving method includes at least one of call receiving acceptance, voice mail box connection, and call receiving rejection. ### Claim 19 (depends on 11) The electronic device of claim 11, wherein the at least the one processor is further configured to verify positions of eyes based on face motion information when e-book contents are displayed, and to change pages when the eyes gaze at a first region. ### Claim 20 (depends on 11) The electronic device of claim 11, wherein the at least the one processor is further configured to change pages based on a face motion direction when e-book contents are displayed.
