This is called a shutter lag, and the mode switching of the camera module is one of the causes of the shutter rack. That is, the camera module may have a preview mode and a capture mode. In the preview mode, the camera module outputs a low resolution image for low power consumption, while in the capture mode for photography, the camera module outputs a high resolution image. However, since a certain time is required for mode switching of the camera module, a shutter rack may occur.

Accordingly, although the user presses the shutter at a desired point in time, there is a problem in that an image of a point in time delayed from the point in time of pressing the shutter is photographed.

An embodiment of the present invention provides a terminal that supports a method of capturing an image of a viewpoint desired by a user.

An image capturing method according to an embodiment of the present invention includes a method of capturing an image by a terminal including a camera, comprising: starting to store an image processed by the camera in a buffer; Detecting a shooting command; And in response to the photographing command, displaying an image stored in the buffer.

Terminal according to an embodiment of the present invention includes a camera including an image sensor; A user input unit which receives a photographing command; A display unit; And a controller which stores the image processed by the camera in a buffer and displays the image stored in the buffer in the display unit in response to the photographing command.

According to various embodiments of the present disclosure, the terminal may capture an image before and after the user presses the shutter, thereby capturing an image of a desired time point.

For example, when the mobile terminal 100 is in the form of a slide phone, it may sense whether the slide phone is opened or closed. In addition, whether the power supply unit 190 is supplied with power, whether the interface unit 170 is coupled to the external device may be sensed. Meanwhile, the sensing unit 140 may include a proximity sensor 141.

The output unit 150 is for generating output related to the visual, auditory or tactile sense and includes a display unit 151, an audio output module 152, an alarm unit 153, and a haptic module 154 .

The display unit 151 displays (outputs) information processed by the mobile terminal 100. For example, when the mobile terminal 100 is in the call mode, a UI (User Interface) or a GUI (Graphic User Interface) associated with a call is displayed. When the mobile terminal 100 is in the video communication mode or the photographing mode, the photographed and / or received video or UI and GUI are displayed.

The display unit 151 may be a liquid crystal display (LCD), a thin film transistor-liquid crystal display (TFT LCD), an organic light-emitting diode (OLED), a flexible display display, and a 3D display.

Some of these displays may be transparent or light transmissive so that they can be seen through.

The rear structure of the display unit 151 may also be of a light transmission type. With this structure, the user can see an object located behind the terminal body through the area occupied by the display unit 151 of the terminal body.

There may be two or more display units 151 according to the embodiment of the mobile terminal 100. For example, the plurality of display units 151 may be spaced apart or integrally disposed on one surface of the mobile terminal 100, or may be disposed on different surfaces.

When the display unit 151 and a sensor for detecting a touch operation (hereinafter, referred to as a touch sensor) form a mutual layer structure (hereinafter referred to as a touch screen), the display unit 151 may be configured in addition to an output device. Can also be used as an input device. The touch sensor may have the form of, for example, a touch film, a touch sheet, a touch pad, or the like.

The touch sensor may be configured to convert a change in a pressure applied to a specific portion of the display unit 151 or a capacitance generated in a specific portion of the display unit 151 into an electrical input signal. The touch sensor can be configured to detect not only the position and area to be touched but also the pressure at the time of touch.

If 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. As a result, the controller 180 can know which area of the display unit 151 is touched.

Referring to FIG. 1, a proximity sensor 141 may be disposed in an inner region of the mobile terminal 100 surrounded by the touch screen or near the touch screen. The proximity sensor 141 refers to a sensor that detects the presence of an object approaching a predetermined detection surface or an object existing in the vicinity of the detection surface without mechanical contact using an electromagnetic force or an infrared ray. The proximity sensor 141 has a longer life than the contact type sensor and its utilization is also high.

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. And to detect the proximity of the pointer by the change of the electric field along the proximity of the pointer when the touch screen is electrostatic. In this case, the touch screen (touch sensor) may be classified as a proximity sensor.

Hereinafter, for convenience of explanation, the act of allowing the pointer to be recognized without being in contact with the touch screen so that the pointer is located on the touch screen is referred to as a "proximity touch", and the touch The act of actually touching the pointer on the screen is called "contact touch." The position where the pointer is proximately touched on the touch screen means a position where the pointer is vertically corresponding to the touch screen when the pointer is touched.

The proximity sensor detects 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, a proximity touch movement state, and the like). Information corresponding to the detected proximity touch operation and the proximity touch pattern may be output on the touch screen.

The sound output module 152 may output audio data received from the wireless communication unit 110 or stored in the memory 160 in a call signal reception, a call mode or a recording mode, a voice recognition mode, a broadcast reception mode, and the like.

[ The audio output module 152 may include a receiver, a speaker, a buzzer, and the like.

The alarm unit 153 outputs a signal for notifying the occurrence of an event of the mobile terminal 100. Examples of events generated in the mobile terminal 100 include call signal reception, message reception, key signal input, touch input, and the like. The alarm unit 153 may output a signal for notifying the occurrence of an event in a form other than the video signal or the audio signal, for example, vibration. The video signal or the audio signal may be output through the display unit 151 or the audio output module 152 so that they may be classified as a part of the alarm unit 153.

The haptic module 154 generates various tactile effects that the user can feel. Vibration is a representative example of the haptic effect generated by the haptic module 154. The intensity and pattern of vibration generated by the haptic module 154 can be controlled. For example, different vibrations may be synthesized and output or sequentially output.

In addition to vibration, the haptic module 154 may be configured to provide a pin array that vertically moves with respect to the contact skin surface, a jetting force or suction force of air through an injection or inlet port, grazing to the skin surface, contact of an electrode, electrostatic force, and the like. Various tactile effects can be generated, such as effects by the endothermic and the reproduction of a sense of cold using the elements capable of endotherm or heat generation.

The haptic module 154 can be implemented not only to transmit the tactile effect through the direct contact but also to allow the user to feel the tactile effect through the muscular sensation of the finger or arm. The haptic module 154 may include two or more haptic modules 154 according to the configuration of the portable terminal 100.

The memory 160 may store a program for the operation of the controller 180 and temporarily store input / output data (e.g., a phone book, a message, a still image, a moving picture, etc.). The memory 160 may store data on vibration and sound of various patterns outputted when a touch is input on the touch screen.

The memory 160 may be a flash memory type, a hard disk type, a multimedia card micro type, a card type memory (for example, SD or XD memory), a RAM (Random Access Memory), SRAM (Static Random Access Memory), ROM (Read Only Memory), EEPROM (Electrically Erasable Programmable Read-Only Memory), PROM A disk, and / or an optical disk. The mobile terminal 100 may operate in association with a web storage that performs a storage function of the memory 160 on the Internet.

The interface unit 170 serves as a path for communication with all external devices connected to the mobile terminal 100. The interface unit 170 receives data from an external device or supplies power to each component in the mobile terminal 100 or transmits data to the external device. For example, a wired / wireless headset port, an external charger port, a wired / wireless data port, a memory card port, a port for connecting a device having an identification module, an audio I / O port, A video input / output (I / O) port, an earphone port, and the like may be included in the interface unit 170.

The identification module is a chip for storing various information for authenticating the use right of the mobile terminal 100 and includes a user identification module (UIM), a subscriber identity module (SIM), a general user authentication module A Universal Subscriber Identity Module (USIM), and the like. Devices with identification modules (hereinafter referred to as "identification devices") can be manufactured in a smart card format. Accordingly, the identification device can be connected to the terminal 100 through the port.

The interface unit may be a passage through which power from the cradle is supplied to the mobile terminal 100 when the mobile terminal 100 is connected to an external cradle, or various command signals input from the cradle by a user may be transferred. It may be a passage that is delivered to the terminal 100. Various command signals or power input from the cradle may be operated as signals for recognizing that the mobile terminal 100 is correctly mounted on the cradle.

The controller 180 typically controls the overall operation of the mobile terminal 100. For example, voice communication, data communication, video communication, and the like. The control unit 180 may include a multimedia module 181 for multimedia playback.

According to a software implementation, embodiments such as procedures or functions may be implemented with separate software modules that perform at least one function or operation. The software code may be implemented by a software application written in a suitable programming language. The software code may be stored in the memory 160 and executed by the controller 180.

Next, an image capturing method according to an exemplary embodiment of the present invention will be described with reference to FIG. 2.

2 is a flowchart illustrating an image capturing method according to an exemplary embodiment of the present invention.

When the camera 121 of the mobile terminal 100 is activated (S101), the controller 180 may receive user selection information regarding the size of a buffer for storing an image or a cycle in which the image is stored in the buffer. (S103). The buffer may temporarily store an image processed by the camera 121. The buffer may be part of the memory 160 or may be a storage device separate from the memory 160. In this case, the resolution of the image may be automatically adjusted according to the size of the buffer or the period in which the image is stored in the buffer. Therefore, the controller 180 may determine the size of the buffer or the buffering period of the image according to a user's selection, thereby obtaining an image having a resolution suitable for a photographing purpose.

Subsequently, the controller 180 may start storing the image processed by the camera 121 in the buffer (S105). Since the preview mode of the camera 121 outputs a low resolution image, a low resolution image may be stored in the buffer, but the present invention is not limited thereto.

On the other hand, if the controller 180 detects a shooting command (S107), the controller 180 may display an image stored in a buffer based on a time point when the shooting command is detected (S109).

Subsequently, the controller 180 may select some of the images displayed on the display unit 151 (S111). Since there is a high possibility that the user intends to photograph an image among the plurality of images stored immediately before the controller 180 receives a photographing command from the user, an image desired by the user may be output even if a shutter rack phenomenon occurs. As a result, the user can save the power of the terminal, for example, by selecting a desired image among the buffered low resolution images, storing the image as a high resolution image, and deleting the rest.

Meanwhile, according to an embodiment of the present disclosure, the controller 180 may omit post-processing to remove noise of an image processed by the camera 121. Since the time for storing the image is delayed by the time required for post-processing, the problem caused by the shutter rack can be solved by omitting the post-processing, thereby achieving the object of the present invention.

However, according to another embodiment of the present invention, the controller 180 omits the post-processing until the step (S105) of storing the image in the buffer so that the time required for post-processing is shortened while providing the image from which the noise is removed. In the step S107 of detecting the photographing command, the plurality of images may be post-processed at one time. In addition, the step of performing the post-processing is not limited thereto.

Next, an image capturing method according to another exemplary embodiment will be described with reference to FIG. 3.

3 is a flowchart illustrating an image capturing method according to another exemplary embodiment.

When the camera 121 of the mobile terminal 100 is activated (S201), the controller 180 may receive user selection information regarding the size of a buffer for storing an image or a cycle in which the image is stored in the buffer (S203). . However, the user selection information is not necessarily received every time the camera is activated, and may be omitted. The camera 121 may operate in the preview mode until the photographing command is detected.

Subsequently, when the controller 180 detects an image buffering start command (S205), the controller 180 may start storing the image processed by the camera 121 in the buffer in response to the image buffering start command (S207). ). The image buffering start command includes a camera activation command, a user input unit operation for image buffering, a half shutter operation, a motion stop of the terminal for a predetermined time, a background image stop, an image input of a predetermined shape, and the like. Among these, the image capturing method by the camera activation command is the same as the image capturing method described with reference to FIG. 2. This means that image buffering is started at the same time the camera 121 of the mobile terminal 100 is activated.

On the other hand, if the controller 180 detects an image buffering stop command (S209), the controller 180 stops storing the image processed by the camera 121 in the buffer (S211). If the user does not require image buffering, the controller 180 can reduce power consumption by stopping storing the image in the buffer. The image buffering stop command detecting step S209 and the image buffering stopping step S211 may be used in the image capturing method described with reference to FIG. 2. The image buffering stop command may include a camera 121 deactivation command, an operation of a user input unit for stopping image buffering, an interruption of a half shutter operation, a movement of the terminal 100, a movement of a background image, an interruption of an image input of a predetermined shape, and the like. Can be.

On the other hand, when the controller 180 does not detect an image buffering stop command and detects a shooting command (S213), the controller 180 stores a plurality of images stored in the buffer until the detection command is detected. Can be displayed (S215).

Subsequently, the controller 180 may select some images from among the plurality of displayed images (S217).

Meanwhile, the controller 180 may capture an image according to an embodiment of the present invention without removing noise of the image processed by the camera 121. However, according to another exemplary embodiment of the present disclosure, the post-noise post-processing may be executed at step S213 of detecting a shooting command, but is not limited thereto.

The following describes image buffering according to an embodiment of the present invention with reference to FIG. 4.

4 is a diagram for describing image buffering according to an exemplary embodiment.

The controller 180 may display an image obtained by the image sensor included in the camera 121 on the preview screen 10. The controller 180 can supply a low resolution image to the preview screen 10 for a faster image processing speed.

In a state where a low resolution image is supplied to the preview screen 10, the controller 180 may detect an image buffering start command. For example, the controller 180 may activate a camera 121, an operation of the user input unit 130 for image buffering, an operation of a half shutter, a movement of the terminal 100 is stopped for a predetermined time, and a background image is stopped. By detecting an image of a predetermined shape, an image buffering start command may be detected.

When the controller 180 detects a camera 121 activation command, when the user activates the camera 121 of the terminal 100, the controller 180 can display the processed image from the camera 121 without any setting. It means to start storing in the buffer. However, since continuously storing the image in the buffer requires a lot of power consumption, it is necessary to detect the time point at which the user intends to shoot and perform image buffering only before the shooting for low power consumption.

When the controller 180 detects an operation of the user input unit 130 for image buffering, the controller 180 detects input data using a keypad, a dome switch, a touch pad, etc. constituting the user input unit 130. If it is. That is, the controller 180 starts to store the processed image from the camera 121 in the buffer from the time when the input data enters the user input unit 130.

In addition, an image buffering start command may be sensed through the A / V input unit 120, the user input unit 130, the sensing unit 140, and the like of the mobile terminal 100. The controller 180 detects that the half shutter of the user input unit 130 operates, or that the sensing unit 140 stops the movement of the terminal 100 for a predetermined time, or the camera of the A / V input unit 120. When the image sensor included in the 121 detects a still state of the background image or an image having a predetermined shape, the image sensor from the camera 121 starts to store the processed image in the buffer. As such, when the controller 180 performs image buffering only in a section between the time when the sensing unit detects the shooting intention and the time when the sensing command is sensed, the controller 180 may reduce power consumption.

Subsequently, the controller 180 can store a plurality of low resolution images in a buffer (20). The controller 180 may store an image in a circular queue buffer for continuous image buffering. In the case of using the annular queue structure, since the oldest image is deleted while the new image is input, the new image can be stored, so that the controller 180 can continuously store the image in a buffer having a limited capacity.

Images stored in the buffer may be stored in a low resolution, for example, YUV, depending on the characteristics of the image sensor. The advantage of storing low resolution images in the buffer is that they speed up image processing. However, the present invention is not limited to the YUV scheme and may be stored as data of a red green blue (RGB), a hue saturation (HSB), a lab, a joint photographic coding experts group (JPEG) scheme, and the like.

The controller 180 may adjust the size of the buffer or the period in which the image is stored in the buffer. The size of the buffer determines the number of images stored in the buffer. Since the capacity of the buffer is limited, the number of images that can be stored in the buffer is limited. That is, as the number of stored images increases, the resolution of each image is lowered. As the storage period of the image becomes longer, the resolution of each image becomes higher. Therefore, the controller 180 may control the resolution of the image by adjusting the size of the buffer or the image storage period according to the photographing purpose of the user.

The controller 180 may stop image buffering by detecting an intention of the user to stop capturing a subject for low power consumption. The controller 180 may detect an image buffering stop command at the stage where image buffering is being performed. However, after stopping image buffering, the controller 180 may execute image buffering again when another image buffering command is detected.

Next, an image storing method during shooting according to an exemplary embodiment will be described with reference to FIG. 5.

FIG. 5 is a diagram for describing an operation of storing an image stored in a buffer and a photographed image according to an exemplary embodiment.

The controller 180 can detect a shooting command (30). The controller 180 may detect a case in which the dome switch or the touch pad of the user input unit 130 used as a shutter is completely pressed by a photographing command, but is not limited thereto.

The controller 180 may display a plurality of images 20 stored in the buffer described with reference to FIG. 3 when the photographing command is detected 30. All or a part of the images may be selected or deleted according to the user's selection from among the plurality of displayed images. Subsequently, the controller 180 encodes only the selected image into one group (40) and stores the stored images in the memory 160 for each group (50).

Next, a method of displaying a stored image according to an exemplary embodiment will be described with reference to FIG. 6.

6 is a front view of a terminal displaying a stored image according to an embodiment of the present invention.

The controller 180 can display the plurality of images stored in the buffer on the display unit 151. The controller 180 may display all of the plurality of images by arranging all of the plurality of images in a line in the display unit 151 (60). In addition, the controller 180 may list the plurality of images in the form of a slide show on the entire display unit 151 or display the divided display unit 151 at once, but is not limited thereto.

The controller 180 may store only an image selected by the user from among the plurality of displayed images (70).

According to an embodiment of the present invention, the above-described method can be implemented as a code readable by a processor on a medium on which a program is recorded. Examples of the medium that can be read by the processor include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, etc., and may be implemented in the form of a carrier wave (e.g., transmission over the Internet) .

The mobile terminal described above can be applied to not only the configuration and method of the embodiments described above but also all or some of the embodiments may be selectively combined so that various modifications may be made to the embodiments It is possible.
