4, when the eye flicker detection mode is selected among various shooting modes for the camera 121, the control unit 180 activates the detection unit 182 for eye flicker detection (S400).

Next, the camera 121 continuously captures an object based on the signal input through the user input unit 130 (S405). The control unit 180 generates one or more continuous shooting images in accordance with the continuous shooting. The number of times of shooting for one continuous shooting input, that is, the number of continuous shooting images, can be set by the user. In general, the continuous shot image will be a portrait image.

Next, the control unit 180 temporarily stores the generated continuous shooting image in the memory 160 (S410). Since the continuous shooting image is temporarily stored, if at least one of the continuous shooting images is stored, it may be deleted from the memory 160. [ Therefore, since the continuous shooting image is not stored at all, the memory 160 can be efficiently used. Here, the generated continuous shooting image may mean that the image input through the camera 121 is converted into digital data. The generated continuous shooting image may be stored in the memory 160 in an area serving as a temporary memory, i.e., a buffer memory.

Next, the detection unit 182 analyzes each consecutively captured image temporarily stored in the memory 160, detects the face region, and detects blinking in the detected face region (S415). Eye blinking can be detected by analyzing the shape of the pupil displayed in the image, and the shape of the pupil can be analyzed using muscle or eye moisture around the eye.

Next, in operation S420, the controller 180 determines whether there is at least one image in which the blinking is not detected in the continuous shooting image as a result of the detection by the detecting unit 182. That is, the number of images in which blinking is not detected may be equal to or less than the number of continuous shooting images.

If it is determined in step S420 that there is an image in which eye blindness is not detected, the control unit 180 displays the image on which the blinking is not detected on the display unit 151 (S420). Since there may be more than one image in which blinking is not detected, the controller 180 may display a plurality of images on the display unit 151 in the form of a thumbnail. The control unit 180 may display only the image on which the degree of flicker of the eye is equal to or higher than the predetermined reference on the display unit 151 among the images in which blinking is not detected. For example, if the detection result of the detection unit 182 indicates 1 when the eye is largely opened, and 0 when the eye is closed, only the image with the eye size of 0.5 or more can be displayed on the display unit 151 . The criterion for the degree of eye blinking can be set to the user. Next, one or more images displayed on the display unit 151 are selected (S430). For example, of the nine images displayed in thumbnail form, two images can be selected. Next, the controller 180 stores the selected one or more images in the memory 160 (S435). Which is temporarily stored in that it is not deleted unless there is a specific reason such as user deletion or device error. The image which is not stored in step S435 of the continuous shooting image temporarily stored in step S410 may be deleted immediately after the storing of step S435 or may be deleted from the memory 160 after a predetermined time has elapsed according to the setting of the user . Also, in step S435, an image that has not been stored may be stored in the memory 160 according to a user selection.

On the other hand, if it is determined in S420 that there is no image in which blinking is not detected, the control unit 180 displays a notification on the display unit 151 indicating that no blinking image is detected (S440). Next, the control unit 180 determines whether re-imaging using the camera 121 is selected (S445). If it is determined in step S445 that the resume is selected, the camera 121 continuously photographs the subject based on the signal input through the user input unit 130 (step S405). In step S405, another subject can be photographed in the case of re-imaging. On the other hand, if it is determined in S445 that the re-photographing is not selected, the process for storing an image in which blinking is not detected is terminated.

5 is a flowchart illustrating a method of controlling an operation of a portable terminal according to a second embodiment of the present invention.

As shown in FIG. 5, when the smile detection mode is selected among various shooting modes for the camera 121, the control unit 180 activates the detection unit 182 for smile detection (S500).

Next, the camera 121 continuously photographs the subject by the signal input through the user input unit 130 (S505). The control unit 180 generates one or more continuous shooting images in accordance with the continuous shooting.

Next, the control unit 180 temporarily stores the generated continuous shooting image in the memory 160 (S510). Since the continuous shooting image is temporarily stored, if at least one of the continuous shooting images is stored, it may be deleted from the memory 160. [

Next, the detecting unit 182 analyzes each continuous shot image temporarily stored in the memory 160, detects the face portion, and detects smile at the detected face portion (S515).

Next, in operation S520, the control unit 180 determines whether there is one or more smile-detected images among the continuous shot images as a result of the detection by the detection unit 182.

As a result of the determination in step S520, if there is an image in which a smile is detected, the control unit 180 displays the smile-detected image on the display unit 151 (S420). The plurality of images in which the smile is detected may be displayed on the display unit 151 in the form of thumbnails. The control unit 180 can display only the image of which the degree of smile is higher than the predetermined reference, on the display unit 151, among the smile detected images. Here, the degree of smile can be set based on the movement of the muscles around the mouth, and the criterion for the degree of smile can be set to the user. Next, one or more images displayed on the display unit 151 are selected (S530). Next, the control unit 180 stores the selected one or more images in the memory 160 (S535). The image that is not stored in step S535 of the continuous shooting image temporarily stored in step S510 may be deleted immediately after the storing of step S535 or may be deleted from the memory 160 after a predetermined time has elapsed according to the setting of the user have.

On the other hand, if it is determined in operation S520 that the smile-detected image does not exist, the control unit 180 displays a notification on the display unit 151 that the smile-detected image is absent (S540). Next, the control unit 180 determines whether re-imaging using the camera 121 is selected (S545). If it is determined in step S545 that the re-imaging is selected, the camera 121 continuously photographs the subject based on the signal input through the user input unit 130 (S505). In S505, another subject can be photographed in the case of re-photographing. On the other hand, if it is determined in S545 that the re-photographing is not selected, the process for storing the smile-detected image ends.
