Representative sensors among various sensors that may be included in the sensing unit 140 will be described in more detail.

First, the proximity sensor 141 refers to a sensor that detects the presence of an object approaching a predetermined detection surface, or the presence of an object in the vicinity of the detection surface, without mechanical contact by using electromagnetic force or infrared rays. The proximity sensor 141 may be disposed in the inner area of the mobile terminal or in proximity to the touch screen, which is covered by the touch screen.

Examples of the proximity sensor 141 include a transmission type photoelectric sensor, a direct reflection type photoelectric sensor, a mirror reflection type photoelectric sensor, a high frequency oscillation type proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. In the case where the touch screen is electrostatic, the proximity sensor 141 can be configured to detect the proximity of the object with a change of the electric field along the proximity of the object having conductivity. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of explanation, the act of recognizing that the object is located on the touch screen in proximity with no object touching the touch screen is referred to as "proximity touch & The act of actually touching an object on the screen is called a "contact touch. &Quot; The position at which the object is closely touched on the touch screen means a position where the object corresponds to the touch screen vertically when the object is touched. The proximity sensor 141 can detect a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, have. Meanwhile, the control unit 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern sensed through the proximity sensor 141 as described above, and further provides visual information corresponding to the processed data It can be output on the touch screen. Furthermore, the control unit 180 can control the mobile terminal 100 such that different operations or data (or information) are processed according to whether the touch to the same point on the touch screen is a proximity touch or a touch touch .

The touch sensor uses a touch (or touch input) applied to the touch screen (or the display unit 151) by using at least one of various touch methods such as a resistance film type, a capacitive type, an infrared type, an ultrasonic type, Detection.

The touch sensor may be configured to detect a position, an area, a pressure at the time of touch, a capacitance at the time of touch, and the like where a touch object touching the touch screen is touched on the touch sensor. Here, the touch object may be a finger, a touch pen, a stylus pen, a pointer, or the like as an object to which a touch is applied to the touch sensor.

Thus, when there is a touch input to the touch sensor, the corresponding signal (s) is sent to the touch controller. The touch controller processes the signal (s) and transmits the corresponding data to the controller 180. Thus, the control unit 180 can know which area of the display unit 151 is touched or the like. Here, the touch controller may be a separate component from the control unit 180, and may be the control unit 180 itself.

On the other hand, the control unit 180 may perform different controls or perform the same control according to the type of the touch object touching the touch screen (or a touch key provided on the touch screen). Whether to perform different controls or to perform the same control according to the type of the touch object may be determined according to the current state of the mobile terminal 100 or an application program being executed.

Touch can be sensed.

The ultrasonic sensor can recognize the position information of the object to be sensed by using ultrasonic waves. Meanwhile, the controller 180 can calculate the position of the wave generating source through the information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the fact that the light is much faster than the ultrasonic wave, that is, the time when the light reaches the optical sensor is much faster than the time the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generating source can be calculated using the time difference with the time when the ultrasonic wave reaches the reference signal.

The camera 121 includes at least one of a camera sensor (for example, a CCD, a CMOS, etc.), a photo sensor (or an image sensor), and a laser sensor.

The camera 121 and the laser sensor may be combined with each other to sense a touch of the sensing object with respect to the three-dimensional stereoscopic image. The photosensor can be laminated to the display element, which is adapted to scan the movement of the object to be detected proximate to the touch screen. More specifically, the photosensor mounts photo diodes and TRs (Transistors) in a row / column and scans the contents loaded on the photosensor using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor performs coordinate calculation of the object to be sensed according to the amount of change of light, and position information of the object to be sensed can be obtained through the calculation.

3 is a view for explaining a video control method of the watch-type mobile terminal 100 according to an embodiment of the present invention.

Referring to FIG. 3, a beam project function can be executed in a state where a wrist-type mobile terminal 100 is worn by a user. For example, when the user presses a finger to make a "pop" sound, the microphone formed on the main body of the mobile terminal 100 senses this and the controller 180 controls the muscle movement sensor 143, The second camera 121a, or the infrared sensor. Then, the control unit 180 recognizes the hand operation of the user from the input means, and executes the beam project function when it is determined that the user is holding the screen 500 such as white paper.

When the beam project function is executed, the test image 510 may be emitted from the light output unit 154. When the user holds a screen 500 such as a white paper and the test image 510 is emitted, the second camera 121a takes a test image 510.

The test image 510 may be, for example, a monochromatic light of red color, and may be outputted while varying in various sizes. The second camera 121a captures the test image 510. When the image captured by the second camera 121a is analyzed, the image output to the inside of the screen 500 is determined as a single color of red color And the image output to the outside of the screen 500 is determined as the background color behind the screen 500, so that the portion of the screen 500 captured in a single color can be determined as the size and position of the screen 500.

Accordingly, the controller 180 may analyze the test image 510 captured by the second camera 121a and adjust the size of the image so that the image is output to the inside of the screen 500.

The control unit 180 compares the color of the test image 510 emitted through the optical output unit 154 with the color of the test image 510 captured by the second camera 121a, The color of the test image 510 and the image to be outputted later through the light output unit 154 is adjusted so that the test image 510 of the correct color is displayed on the display unit 500. When the screen 500 is not white, the test image 510 is displayed in a distorted color, so that an image corresponding to the color of the screen 500 is emitted through the color of the actually captured test image 510 . For example, since the screen 500 is not white, when the actually photographed test image 510 is displayed in a distorted color of an image emitted from the light output unit 154, 154 adjusts the color of the image outputted from the light output unit 154 so that the color of the image outputted from the light output unit 154 can be seen as an undistorted color.

When the size, position, and color of the image are adjusted, an image may be output through the light output unit 154. The image may be an image stored in the memory 170 or transmitted from the outside in real time A video, an internet web site, a menu screen of the mobile terminal 100, and the like.

Accordingly, the user can view an image or the like, which is difficult to view in a small size, through the display unit 151 of the watch-type mobile terminal 100 through the screen 500 as a large screen.
