     The method may further include adjusting a level of applying the first and second image effects to the image in response to a second input. 
     In the method, each of the first and second inputs may be a touch-and-drag input. 
     In the method, the first input may be the touch-and-drag input in a first direction and the second input may be the touch-and-drag input in a second direction being different from the first direction. 
     In the method, the changing the displayed image based on the adjusted combining ratio may include differently changing a first portion of the image and a second portion of the image different from the first portion, based on a combining ratio of the first image effect. 
     In the method, the changing the displayed image based on the adjusted combining ratio may include changing a first portion of the image without changing a second portion of the image different from the first portion, based on a combining ratio of the first image effect. 
     The method may further include creating and storing a third image effect by combining the first and second image effects in response to a third input. 
     The method may further include, when the plurality of image effects includes a third image effect, adjusting a combining ratio among the first, second and third image effects within a predetermined range. 
     The method may further include, when the plurality of image effects includes a third image effect, adjusting a combining ratio to apply cumulatively the first, second and third image effects to the image.

       FIG. 4  is a block diagram illustrating an example electronic device according to various example embodiments of the present disclosure. The electronic device illustrated in  FIG. 4  may be the electronic device  101  illustrated in  FIG. 1 , the electronic device  201  illustrated in  FIG. 2 , and the like. 
     As illustrated in  FIG. 4 , the electronic device may include, but not limited to, a processor (e.g., including processing circuitry)  410  and a display  420 . In various embodiments, the electronic device may further include any other essential or optional elements. For example, the electronic device may be configured to include an input module (e.g., a touch panel, a hard key, a proximity sensor, a biosensor, etc.), a power supply unit, a memory, and/or the like. 
     According to various embodiments, the display  420  may be implemented in the form of a touch screen. The display  420  may be the display  160  illustrated in  FIG. 1  or the display  260  illustrated in  FIG. 2 . The display  420  may be coupled with, for example, the input device  250  illustrated in  FIG. 2 . Also, the display  420  may be implemented as a touch screen, for example, in combination with the touch panel  252  shown in  FIG. 2 . 
     The display  420  may receive a touch, gesture, proximity, or hovering input, for example, using an electronic pen or a part of user&#39;s body. The display  420  may display various kinds of contents (e.g., images, videos, web pages, application execution screens, etc.), based on the control of the processor  410 . 
     According to various embodiments, the display  420  may also display an image effect list that contains a plurality of image effects being applicable to the displayed contents, based on the control of the processor  410 . The image effect may refer to changing the color, saturation, brightness, contrast, focus, etc. of the whole or part of an image. 
     The display  420  may display an image to which the image effect selected from the image effect list by the user is applied, based on the control of the processor  410 . In addition, the display  420  may display an image to which a plurality of image effects selected from the image effect list by the user are simultaneously applied, based on the control of the processor  410 . 
     The processor  410  may include various processing circuitry and control the display  420  to display an image and may also control the display  420  to display an image to which the above-mentioned image effect is applied. For example, the processor  410  may control the display  420  to display a first image or display a second image created by applying a selected image effect to the first image. 
     According to various embodiments, the processor  410  may manage a plurality of image effects. Managing the image effects may include, for example, storing the image effects in a memory (e.g., the memory  130  illustrated in  FIG. 1  or the memory  230  illustrated in  FIG. 2 ), reading out the image effects from the memory, and applying the image effects to an image. In addition, managing the image effects may further include deleting the image effect(s), downloading new image effect(s), creating a new image effect by combining the image effects, editing the image effect(s), and the like. 
     For example, the processor  410  may create and store the image effect list, based on a user&#39;s preference. For example, the processor  410  may select the image effects frequently used more than a predetermined number of times by the user, and register the selected image effects in the image effect list. In addition, the processor  410  may selectively delete the stored image effect(s) in response to a user&#39;s input of requesting deletion. 
     According to various embodiments, the processor  410  may combine a plurality of image effects into a single image effect in response to a user&#39;s input of requesting combination of image effects. Also, in response to corresponding user&#39;s inputs, the processor  410  may adjust a combining ratio between the plurality of image effects and adjust a level (e.g., the degree to be applied) of the combined image effects. For example, the processor  410  may display an image on the display  420  and display an image effect list that contains a first image effect and a second image effect. Then the processor  410  may adjust, in response to a first input, a combining ratio between the first and second image effects and also adjust, in response to a second input, a level of applying a third image effect created by combining the first and second image effects to the image. 
     The processor  410  may download image effects. For example, in response to a corresponding user&#39;s input, the processor  410  may download image effects from an external entity (e.g., a network, an email, a messenger, a detachable external memory, etc.). Further, the processor  410  may download data (e.g., image effect names, image effect icons, image effect types, etc.) associated with the downloaded image effects and manage the downloaded data with the image effects. 
       FIGS. 5A, 5B and 5C  are diagrams illustrating an example process of combining image effects to be applied to an image in an electronic device according to various example embodiments of the present disclosure. 
     As illustrated in  FIG. 5A , the electronic device  101  may display an image  510  on the display  420  and also display an image effect list  520  that is applicable to the image  510 . The image effect list  520  may contain at least one or more image effects. The electronic device  101  may display such image effects by means of image effect names or icons representative of the image effects. Also, the electronic device  101  may apply the respective image effects to the image  510  displayed on the display  420 . 
     According to various embodiments, the electronic device  101  may dispose the image effect list  520  horizontally at the bottom of the display  420 . This is, however, an example only and not to be construed as a limitation. Alternatively, the electronic device  101  may dispose the image effect list  520  vertically at the right or left end of the display  420 . If the display  420  has a bent portion at edges thereof, the electronic device  101  may display the image effect list  520  in the bent portion of the display  420 . Meanwhile, the position of the image effect list  520  disposed on the display  420  may be changed by the user. If there is no selection for the image effect list  520  for a given time, the electronic device  101  may stop displaying the image effect list  520 . 
     When an input, e.g., a user&#39;s input, e.g., a touch-and-drag input, occurs with regard to the image effect list  520 , the electronic device  101  may newly display an image effect which is not displayed on the display  420 . For example, when the image effect list  520  is displayed at the bottom of the display  420 , the electronic device  101  may newly display non-displayed image effect(s) on the display  420  while moving all the image effects leftward or rightward in response to the touch-and-drag input. 
     Alternatively, when a user&#39;s input, e.g., a touch-and-swipe input, occurs with regard to the image effect list  520 , the electronic device  101  may newly display an image effect which is not displayed on the display  420 . For example, when the image effect list  520  is displayed at the bottom of the display  420 , the electronic device  101  may newly display non-displayed image effect(s) on the display  420  while moving all the image effects leftward or rightward in response to the touch-and-swipe input. 
     The order of image effects displayed in the image effect list  520  may be changed. For example, if the user selects one of the displayed image effects through a long touch and then drags it, the electronic device  101  may move the position of the selected image effect according to the user&#39;s drag. 
     The electronic device  101  may display the image effect, selected by the user, distinctively from the unselected image effects. For example, the electronic device  101  may add a box mark  530  around the image effect  522  selected by the user, or add any other distinguishable mark (e.g., v) in the selected image effect  522 . 
     When a certain image effect  522  is selected by the user, the electronic device  101  may display a user interface (UI)  540  for adjusting a level of applying the selected image effect  522  to the image  510 . For example, when any image effect is selected by the user, the electronic device  101  may display a bar-shaped UI  540  capable of adjusting the level of the image effect on the display  420 . Then the user may adjust the level while dragging an indicator in the bar-shaped UI  540 . 
     The user may cancel applying the selected image effect  522  by selecting a “cancel” tab  550 . Also, the user may determine applying the selected image effect  522  by selecting an “apply” tab  555 . 
     As illustrated in  FIGS. 5B and 5C , the electronic device  101  may combine a plurality of image effects. 
     According to various embodiments, in response to a user&#39;s first input, the electronic device  101  may combine the first image effect  522  and the second image effect  523  and may also adjust a combining ratio between the first and second image effects  522  and  523 . The first input may include, for example, but not limited to, a touch input, a touch-and-drag input, a touch-and-swipe input, a physical key input, a hovering input, and the like. Hereinafter, it is assumed that the first input is a touch-and-drag input. 
     As illustrated in  FIG. 5B , the user may create a first input  560  that touches and drags leftward on the display  420  after the first image effect  522  is selected. In response to the first input  560 , the electronic device  101  may combine the second image effect  523 , located at the right of the first image effect  522 , with the first image effect  522 . This is exemplary only and not to be construed as a limitation. Alternatively, in response to the first input  560  that touches and drags leftward on the display  420 , the electronic device  101  may combine the second image effect  521 , located at the left of the first image effect  522 , with the first image effect  522 . 
     In addition, the electronic device  101  may adjust a combining ratio between the first and second image effects  522  and  523 , based on the length of the user&#39;s touch-and-drag input  560 . For example, as the touch-and-drag input  560  moves longer in the left direction on the display  420 , the electronic device  101  may increase a combining ratio of the second image effect  523 . 
     According to various embodiments, in response to the user&#39;s first input  560 , the electronic device  101  may display a current combining ratio between the image effects  522  and  523  as tab-shaped Uls  570  and  580  instead of the previously displayed cancel and apply tabs  550  and  555 . For example, the electronic device  101  may display information respectively indicating the combining ratio  570  of the first image effect and the combining ratio  580  of the second image effect at the top of the display  420 . 
     In addition, in response to the user&#39;s first input  560 , the electronic device  101  may display only the currently combined image effects  522  and  523  rather than all the image effects contained in the image effect list  520 . For example, the electronic device  101  may display, instead of the image effect list  520 , only the first and second image effects  522  and  523  being currently applied to the image  510  at the bottom of the display  420 . Also, the electronic device  101  may resize a tab for displaying each of the first and second image effects  522  and  523 , based on the combining ratio between the first and second image effects  522  and  523 . 
     As illustrated in  FIG. 5C , the user may create the first input  560  that touches and drags rightward on the display  420  after the first image effect  522  is selected. In response to the first input  560 , the electronic device  101  may combine the second image effect  521 , located at the left of the first image effect  522 , with the first image effect  522 . This is exemplary only and not to be construed as a limitation. Alternatively, in response to the first input  560  that touches and drags rightward on the display  420 , the electronic device  101  may combine the second image effect  523 , located at the right of the first image effect  522 , with the first image effect  522 . 
     In addition, the electronic device  101  may adjust a combining ratio between the first and second image effects  522  and  521 , based on the length of the user&#39;s touch-and-drag input  560 . For example, as the touch-and-drag input  560  moves longer in the right direction on the display  420 , the electronic device  101  may increase a combining ratio of the second image effect  521 . 
     According to various embodiments, in response to the user&#39;s first input  560 , the electronic device  101  may display a current combining ratio between the image effects  521  and  522  as tab-shaped Uls  590  and  570  instead of the previously displayed cancel and apply tabs  550  and  555 . For example, the electronic device  101  may display information respectively indicating the combining ratio  570  of the first image effect and the combining ratio  590  of the second image effect at the top of the display  420 . 
     In addition, in response to the user&#39;s first input  560 , the electronic device  101  may display only the currently combined image effects  521  and  522  rather than all the image effects contained in the image effect list  520 . For example, the electronic device  101  may display, instead of the image effect list  520 , only the first and second image effects  522  and  521  being currently applied to the image  510  at the bottom of the display  420 . Also, the electronic device  101  may resize a tab for displaying each of the first and second image effects  522  and  521 , based on the combining ratio between the first and second image effects  522  and  521 . 
     The screen that appears on the display  420  in response to the user&#39;s first input as illustrated in  FIGS. 5B and 5C  may be changed continuously according to the first input. For example, while the touch-and-drag input  560  is varied in length after being started, the electronic device  101  may continuously change the combining ratio between the first image effect  522  and the second image effect  523  or  521 . Also, based on the combining ratio being continuously changed, the electronic device  101  may continuously change the combined image effects applied to the image  510  displayed on the display  420 . 
     Such a change of the screen is not limited to a variation in length of the touch-and-drag input  560 . According to another embodiment, while the touch-and-drag input  560  is varied in direction after being started, the electronic device  101  may continuously change the combining ratio between the first image effect  522  and the second image effect  523  or  521 . Also, based on the combining ratio being continuously changed, the electronic device  101  may continuously change the combined image effects applied to the image  510  displayed on the display  420 . 
     According to still another embodiment, while the touch-and-drag input  560  is varied in input time after being started, the electronic device  101  may continuously change the combining ratio between the first image effect  522  and the second image effect  523  or  521 . Also, based on the combining ratio being continuously changed, the electronic device  101  may continuously change the combined image effects applied to the image  510  displayed on the display  420 . 
     According to yet another embodiment in which the first input  560  is a touch input, while the touch input  560  is varied in input strength after being started, the electronic device  101  may continuously change the combining ratio between the first image effect  522  and the second image effect  523  or  521 . Also, based on the combining ratio being continuously changed, the electronic device  101  may continuously change the combined image effects applied to the image  510  displayed on the display  420 . 
     Similarly, in response to the first input, the electronic device  101  may change information displayed at the top and bottom of the display  420  to indicate the combining ratio between the image effects. For example, in parts (b) and (c) of  FIG. 5 , the electronic device  101  may change the combining ratio of the first image effect from 100% to 0% and simultaneously change the combining ratio of the second image effect from 0% to 100%. 
     For example, in  FIGS. 5B and 5C , the electronic device  101  may gradually reduce the size of the tab for displaying the first image effect  522  at the bottom of the display  420  and may also gradually increase the size of the tab for displaying the second image effect  523  or  521 . 
     Therefore, the user may check the result of actually applying the combined image effects to the image  510  displayed on the display  420  while adjusting the combining ratio between the combined image effects. 
       FIGS. 6A, 6B and 6C  are diagrams illustrating an example process of adjusting a level of combined image effects in an electronic device according to various example embodiments of the present disclosure. 
       FIG. 6A  may correspond to  FIG. 5B or 5C . As illustrated in  FIG. 6A , the electronic device  101  may combine the first image effect  522  and the second image effect  523  in response to the user&#39;s first input. 
     According to various embodiments, in response to the user&#39;s first input, the electronic device  101  may display information for indicating the combining ratio  570  of the first image effect and the combining ratio  580  or  590  of the second image effect at the top of the display  420 . 
     Also, in response to the user&#39;s first input  560 , the electronic device  101  may display only the first and second image effects  522  and  521  being currently applied to the image  510  at the bottom of the display  420 . In this case, the electronic device  101  may resize a tab for displaying each of the first and second image effects  522  and  521 , based on the combining ratio between the first and second image effects  522  and  521 . 
     As illustrated in  FIG. 6B , the user may create a second input  610  that touches and drags upward on the display  420  after the combining ratio between the first and second image effects  522  and  523  is determined. The second input may include, for example, but not limited to, a touch input, a touch-and-drag input, a touch-and-swipe input, a physical key input, a hovering input, and the like. Hereinafter, it is assumed that the second input is a touch-and-drag input. 
     In response to the user&#39;s second input  610 , the electronic device  101  may adjust a level of applying a new image effect, created by combining the first and second image effects  522  and  523 , to the image  510 . 
     In addition, the electronic device  101  may adjust the level of the new image effect created by combining the first and second image effects  522  and  523 , based on the length of the user&#39;s touch-and-drag input  610 . For example, as the touch-and-drag input  610  moves longer in the upward direction on the display  420 , the electronic device  101  may increase the level of the new image effect. 
     According to various embodiments, in response to the user&#39;s second input  610 , the electronic device  101  may display a suitable UI  620  for indicating the level of the image effect to be applied to the image  510  on the display  420 . For example, the electronic device  101  may display a vertically long bar-shaped UI  620  on the display  420 . In this case, the electronic device  101  may display the level in the bar-shaped UI  620  in response to the user&#39;s second input. The shape and position of the UI  620  for indicating the level are exemplary only and not to be construed as a limitation. 
     Alternatively, the electronic device  101  may display the level of the image effect by using any other shaped UI such as a circular UI. If the display  420  has a bent portion at edges thereof, the electronic device  101  may display the UI  620  for indicating the level of the image effect in the bent portion of the display  420 . The position of the UI  620  disposed on the display  420  may be changed by the user. 
     According to various embodiments, when the user&#39;s touch-and-drag input  610  moves upward on the display  420 , the electronic device  101  may move upward an indicator  621  contained in the UI  620  for indicating the level of the image effect. Simultaneously or sequentially, the electronic device  101  may display a value  622  of the level near or in the UI  620  for indicating the level of the image effect. 
     As illustrated in  FIG. 6C , the user may create the second input  610  that touches and drags downward on the display  420  after the combining ratio between the first and second image effects  522  and  523  is determined. 
     The electronic device  101  may adjust the level of the new image effect created by combining the first and second image effects  522  and  523 , based on the length of the user&#39;s touch-and-drag input  610 . For example, as the touch-and-drag input  610  moves longer in the downward direction on the display  420 , the electronic device  101  may increase the level of the new image effect. 
     Also, in response to the user&#39;s second input  610 , the electronic device  101  may display the UI  620  for indicating the level of the image effect to be applied to the image  510  on the display  420 . 
     For example, when the user&#39;s touch-and-drag input  610  moves downward on the display  420 , the electronic device  101  may move downward the indicator  621  contained in the UI  620  for indicating the level of the image effect. Simultaneously or sequentially, the electronic device  101  may display the level value  622  near or in the UI  620  for indicating the level of the image effect. 
     According to various embodiments, in response to the user&#39;s second input  610 , the electronic device  101  may stop displaying the names of the combined image effects  522  and  523  previously displayed at the bottom of the display  420 . This is, however, exemplary only. Alternatively, the electronic device  101  may continue to display the names of the combined image effects  522  and  523 . 
     The screen that appears on the display  420  in response to the user&#39;s second input  610  as illustrated in  FIGS. 6B and 6C  may be changed continuously according to the second input  610 . For example, while the touch-and-drag input  610  is varied in length after being started, the electronic device  101  may continuously change the level of the new image effect created by combining the first and second image effects  522  and  523 . Also, based on the continuously changed level, the electronic device  101  may continuously change the new image effect applied to the image  510  displayed on the display  420 . 
     Therefore, the user may check the result of actually applying the new image effect to the image  510  displayed on the display  420  while adjusting the level of the new image effect created by combining the image effects. 
       FIG. 7  is a flowchart illustrating an example method for combining a plurality of image effects and adjusting a level for applying the combined image effects to an image in an electronic device according to various example embodiments of the present disclosure. 
     At operation  710 , the electronic device  101  may display an image. For example, the electronic device  101  may read out a stored image from the memory  130  or  230  and display it on the display  420 . In another example, the electronic device  101  may display an image obtained through the camera module  291  on the display  420 . In the latter case, the electronic device  101  may continuously process images obtained through the camera module  291  to display them. Namely, the images obtained through the camera module  291  and displayed on the display  420  may be changed continuously. Such an image obtained through the camera module  291  may be a preview image or a photographed image. 
     At operation  720 , the electronic device  101  may display an image effect list that contains a plurality of image effects including first and second image effects. The electronic device  101  may display such image effects by means of image effect names or icons representative of the image effects. Also, the electronic device  101  may apply the respective image effects to the image displayed on the display  420 . 
     The electronic device  101  according to various embodiments may display all image effects in the image effect list. However, if the number of image effects is greater than a predetermined number, the electronic device  101  may display only the predetermined number of image effects in the image effect list. In this case, the remaining image effects may appear in the image effect list when there is a suitable user&#39;s input. 
     In addition, the electronic device  101  may change the order of image effects displayed in the image effect list in response to a suitable user&#39;s input. Also, the electronic device  101  may display the image effect(s), selected by the user, distinctively from the unselected image effect(s). 
     At operation  730 , in response to a first input for the displayed image, the electronic device  101  may combine the first image effect  522  and the second image effect  523  and may also adjust a combining ratio between the first and second image effects  522  and  523 . The first input may include, for example, but not limited to, a touch input, a touch-and-drag input, a touch-and-swipe input, a physical key input, a hovering input, and the like. Hereinafter, it is assumed that the first input is a touch-and-drag input. 
     The electronic device  101  according to various embodiments may combine the first and second image effects, based on the first image effect selected by the user, in response to the user&#39;s first input. In addition, the electronic device  101  may adjust the combining ratio between the first and second image effects in response to the first input. For example, depending on the length of the first input (e.g., the touch-and-drag input), the electronic device  101  may adjust the combining ratio between the first and second image effects. 
     At operation  740 , the electronic device  101  may adjust a level for applying a new image effect, created by combining the first and second image effects, to the displayed image in response to a second input for the displayed image. The second input may be the same as the above-discussed first input. Hereinafter, it is assumed that the second input is a touch-and-drag input. 
     The electronic device  101  according to various embodiments may adjust, depending on the length of the second input (e.g., the touch-and-drag input), the level of the new image effect created by combining the first and second image effects. 
       FIGS. 8A, 8B and 8C  are diagrams illustrating example cases of combining a plurality of image effects in an electronic device according to various embodiments of the present disclosure. As illustrated in  FIGS. 8A to 8C , the electronic device  101  may variously display an image depending on properties of the image effects to be combined. 
     As described above, in response to the user&#39;s first input, the electronic device  101  may combine the first and second image effects and also adjust the combining ratio. Then, based on the adjusted combining ratio between the first and second image effects, the electronic device  101  may change an image displayed on the display  420 . 
     The first image  810  is, for example, a case where the combining ratio of the first image effect  832  to the second image effect  833  is adjusted to 30% to 70%. The second image  820  is, for example, a case where the combining ratio of the first image effect  832  to the second image effect  833  is adjusted to 70% to 30%. 
     As illustrated in  FIG. 8A , the electronic device  101  may apply a new image effect, created by combining the first and second image effects  832  and  833 , to the image  810  or  820  displayed on the display  420 . Here, the first image effect  832  may mean, for example, changing the color, saturation, brightness, contrast, focus, etc. of the entire or part of the image. 
     The electronic device  101  may differently display the first image  810  and the second image  820 , depending on the combining ratio between the first and second image effects  832  and  833 . For example, in case of the second image  820  where the first image effect  832  is more applied, the electronic device  101  may reflect properties of the first image effect  832  much more. As a result, the second image  820  may be displayed with at least one of color, saturation, brightness, contrast, and focus changed much more in whole or in part compared to the first image  810 . 
     As illustrated in  FIG. 8B , the electronic device  101  may apply a new image effect, created by combining the first and second image effects  832  and  833 , to the image  810  or  820  displayed on the display  420 . Here, the first image effect  832  may be, for example, an image effect of less blurring the central portion of the image and much more blurring the peripheral portion of the image. 
     The electronic device  101  may differently display the first image  810  and the second image  820 , depending on the combining ratio between the first and second image effects  832  and  833 . For example, in case of the second image  820  where the first image effect  832  is more applied, the electronic device  101  may reflect properties of the first image effect  832  much more. As a result, the second image  820  may be displayed with a clearer central portion and a more blurred peripheral portion in comparison with the first image  810 . 
     As illustrated in  FIG. 8C , the electronic device  101  may apply a new image effect, created by combining the first and second image effects  832  and  833 , to the image  810  or  820  displayed on the display  420 . Here, the first image effect  832  may be, for example, an image effect of adding a given image to only a first portion in case of a lower level and adding the given image to both first and second portions in case of a higher level. 
     The electronic device  101  may differently display the first image  810  and the second image  820 , depending on the combining ratio between the first and second image effects  832  and  833 . For example, in case of the second image  820  where the first image effect  832  is more applied, the electronic device  101  may reflect properties of the first image effect  832  much more. As a result, the first image  810  may have the given image added to only the first portion  840 , whereas the second image  820  may have the given image added to both the first and second portions  840  and  850 . 
     As such, the electronic device  101  may alter and display the image in various ways in accordance with the properties of the image effects. 
       FIGS. 9A, 9B and 9C  are diagrams illustrating an example process of storing a new image effect created by combining first and second image effects in an electronic device according to various example embodiments of the present disclosure. 
       FIG. 9A  may correspond to  FIG. 5B or 5C . As illustrated in  FIG. 9A , the electronic device  101  may combine the first image effect  910  and the second image effect  920  in response to the user&#39;s first input. 
     According to various embodiments, in response to the user&#39;s first input, the electronic device  101  may display information for indicating the combining ratio  930  of the first image effect  910  and the combining ratio  935  of the second image effect  920  at the top of the display  420 . 
     Also, in response to the user&#39;s first input, the electronic device  101  may display only the currently applied first and second image effects  910  and  920  at the bottom of the display  420 . In this case, the electronic device  101  may resize a tab for displaying each of the first and second image effects  910  and  920 , based on the combining ratio between the first and second image effects  910  and  920 . 
     According to various embodiments, in response to the user&#39;s third input, the electronic device  101  may store the combined image effects, currently displayed on the display  420 , as a new image effect. For example, when a long touch  940  is received from one point after the first or second input using a touch and drag, the electronic device  101  may recognize the long touch  940  as the user&#39;s third input. 
     As illustrated in  FIG. 9B , in response to the long touch  940 , the electronic device  101  may create and save a new image effect in which the first and second image effects  910  and  920  displayed on the display  420  are combined. In this case, the electronic device  101  may display on the display  420  a notification  960  for indicating that the new image effect Z  950  is completely saved. 
     As illustrated in  FIG. 9C , the electronic device  101  may add the newly created image effect Z  950  in the image effect list. Thereafter, the user may apply the new image effect Z  950  to other images. 
     The name of the new image effect Z  950  may be arbitrarily generated by the electronic device  101 . Also, the electronic device  101  may provide an option to modify the name of the new image effect Z  950 . 
       FIGS. 10A, 10B and 100  are diagrams illustrating an example process of applying an image effect to an image in an electronic device according to various example embodiments of the present disclosure. 
     As illustrated in  FIG. 10A , the electronic device  101  may display an image  1010  on the display  420  and also display an image effect list  1020  that is applicable to the image  1010 . The image effect list  1020  may contain at least one or more image effects. The electronic device  101  may display such image effects by means of image effect names or icons representative of the image effects. Also, the electronic device  101  may apply the respective image effects to the image  1010  displayed on the display  420 . 
     According to various embodiments, the electronic device  101  may dispose the image effect list  1020  horizontally at the bottom of the display  420 . When a user&#39;s input, e.g., a touch-and-drag input, occurs with regard to the image effect list  1020 , the electronic device  101  may newly display an image effect which is not displayed on the display  420 . 
     The order of image effects displayed in the image effect list  1020  may be changed. For example, if the user selects one of the displayed image effects through a long touch and then drags it, the electronic device  101  may move the position of the selected image effect according to the user&#39;s drag. 
     As illustrated in  FIG. 10B , the electronic device  101  may apply a first image effect  1021  to the image  1010  displayed on the display  420 . For example, the electronic device  101  may apply the first image effect  1021  to at least part of the image  1010  displayed on the display  420  in response to a user&#39;s fourth input. The fourth input may be, for example, an input similar to the first or second input described above. 
     According to various embodiments, the electronic device  101  may apply the first image effect  1021  to the image  1010  in response to the user&#39;s fourth input (e.g., a touch-and-drag input  1030 ) that moves leftward on the display  420 . For example, the electronic device  101  may apply the first image effect  1021  to the image  1010  from a right portion of the display  420  in response to the touch-and-drag input  1030  moving leftward on the display  420 . This is, however, exemplary only. Alternatively, the user&#39;s fourth input  1030  may be a touch-and-drag input that moves rightward, upward, or downward on the display  420 . 
     Also, in response to the touch-and-drag input  1030 , the electronic device  101  may display only the currently applied image effect  1021  rather than all the image effects contained in the image effect list  1020 . For example, the electronic device  101  may display only the first image effect  1021  being currently applied to the image  1010  at the bottom of the display  420 . Also, the electronic device  101  may resize a tab for displaying the first image effect  1021 , based on an applied level of the first image effect  1021 . 
     As illustrated in  FIG. 100 , the electronic device  101  may apply the first image effect  1021  to the entire area of the image  1010  displayed on the display  420 . 
     According to various embodiments, when the touch-and-drag input  1030  starting from the right side of the display  420  and moving leftward arrives at the left end of the display  420 , the electronic device  101  may apply the first image effect  1021  to the entire area of the image  1010 . 
     After the first image effect  1021  is applied to the entire area of the image  1010  displayed on the display  420 , the electronic device  101  may display a “cancel” tab  1040  and an “apply” tab  1045  at the top of the display  420 . The user may cancel applying the selected image effect  1021  by selecting the “cancel” tab  1040 , and may also determine applying the selected image effect  1021  by selecting the “apply” tab  1045 . 
     According to various embodiments, when the first image effect  1021  is applied to the entire area of the image  1010  displayed on the display  420 , the electronic device  101  may display the image effect list  1020  again at the bottom of the display  420 . In addition, the electronic device  101  may display on the display  420  a suitable UI  1050  for adjusting a level of the currently applied image effect. 
     Through the above process, the user may simultaneously view a state of applying no image effect and a state of applying the image effect to the image. 
       FIGS. 11A and 11B  are diagrams illustrating example cases of combining three or more image effects in an electronic device according to various example embodiments of the present disclosure. 
     As illustrated in part (a) of  FIG. 11A , the electronic device  101  may display an image  1110  on the display  420  and also display an image effect list  1120  that is applicable to the image  1110 . The image effect list  1120  may contain at least one or more image effects. 
     According to various embodiments, the electronic device  101  may dispose the image effect list  1120  horizontally at the bottom of the display  420 . When a user&#39;s input, e.g., a touch-and-drag input, occurs with regard to the image effect list  1120 , the electronic device  101  may newly display an image effect which is not displayed on the display  420 . The order of image effects displayed in the image effect list  1120  may be changed. Since part (a) of  FIG. 11A  is similar to part (a) of  FIG. 5 , a detailed description thereof will not be repeated. 
     As illustrated in part (b) of  FIG. 11A , the electronic device  101  may display the image effect, selected by the user, distinctively from the unselected image effects. For example, the electronic device  101  may add a distinguishable mark  1130  (e.g., v) in an image effect  1121  selected by the user, or add a box mark around the selected image effect  1121 . 
     When a certain image effect is selected by the user, the electronic device  101  may display a suitable UI for adjusting a level of applying the selected image effect to the image  1110 . For example, when the first image effect  1121  is selected by the user, the electronic device  101  may display a bar-shaped UI  1140  capable of adjusting the level of the first image effect  1121  on the display  420 . Further, the electronic device  101  may display a first indicator  1150  located in the bar-shaped UI  1140  to adjust the level and also display a name  1161  of the selected image effect. While dragging the first indicator  1150 , the user may adjust the applied level of the selected image effect. 
     In this state, the user may select any other image effect to be combined with the preselected first image effect  1121 , and may also adjust the combining ratio between the first image effect  1121  and the selected image effect. 
     As illustrated in part (c) of  FIG. 11A , the electronic device  101  may display two marks  1130  and  1131  for indicating that two image effects  1121  and  1122  are selected by the user. After the image effects  1121  and  1122  are selected by the user, the electronic device  101  may display a suitable UI for adjusting the combining ratio between the selected first and second image effects  1121  and  1122 . 
     For example, the electronic device  101  may add a name  1162  of the second image effect  1122  to the previously displayed bar-shaped UI  1140  for indicating the applied level of the first image effect  1121 . In this case, the user may adjust the combining ratio between the first and second image effects  1121  and  1122  by moving the first indicator  1150 . 
     As illustrated in part (d) of  FIG. 11A , the electronic device  101  may display three marks  1130 ,  1131  and  1132  for indicating that three image effects  1121 ,  1122  and  1123  are selected by the user. After the image effects  1121 ,  1122  and  1123  are selected by the user, the electronic device  101  may display a suitable UI for adjusting the combining ratio among the selected first, second and third image effects  1121 ,  1122  and  1123 . 
     For example, the electronic device  101  may add a second indicator  1151  and a name  1163  of the third image effect  1123  to the previously displayed bar-shaped UI  1140  for indicating the combining ratio between the first and second image effects  1121  and  1122 . In this case, the user may adjust the combining ratio among the first, second and third image effects  1121 ,  1122  and  1123  by moving the first and second indicators  1150  and  1151 . 
     As illustrated in part (a) of  FIG. 11B , the user may adjust the combining ratio among the first, second and third image effects  1121 ,  1122  and  1123  by moving the first and second indicators  1150  and  1151 . 
     Specifically, in the bar-shaped UI  1140  for adjusting the combining ratio of image effects, the length from the left end to the first indicator  1150  may indicate the combining ratio of the first image effect  1121 . In addition, the length between the first and second indicators  1150  and  1151  may indicate the combining ratio of the second image effect  1122 , and the length from the second indicator  1151  to the right end of the bar-shaped UI  1140  may indicate the combining ratio of the third image effect  1123 . 
     Namely, while moving the indicators  1150  and  1151 , the user may adjust the combining ratio between the respective image effects  1121 ,  1122  and  1123  within the total range of values capable of combining the selected image effects. 
     According to various example embodiments, the electronic device  101  may change continuously the image effects applied to the image  1110  displayed on the display  420 , based on the combining ratio among the image effects  1121 ,  1122  and  1123  being varying according to the movement of the indicators  1150  and  1151 . Therefore, the user may check the result of actually applying the combined image effects to the image  1110  displayed on the display  420  while adjusting the combining ratio among the combined image effects. 
     As illustrated in part (b) of  FIG. 11B , the electronic device  101  may store the combined image effects, currently displayed on the display  420 , as a new image effect. The electronic device  101  may store the new image effect when a “save” tab  1170  displayed at the top of the display  420  is selected, or may store the new image effect in response to the third input as described in part (b) of  FIG. 9 . The electronic device  101  may add the newly stored image effect  1124  to the image effect list  1120 , and may display a suitable UI  1180  for adjusting a level of the new image effect  1124 . 
     Part (c) of  FIG. 11B  illustrates another embodiment of the UI for adjusting the combining ratio among the selected first, second and third image effects  1121 ,  1122  and  1123 . For example, the electronic device  101  may display a triangular UI  1190  instead of the previously displayed bar-shaped UI  1140  for indicating the combining ratio between the first and second image effects  1121  and  1122 . 
     The triangular UI  1190  may have divided inner regions and display each image effect name in each region. Each inner region of the triangular UI  1190  may represent the combining ratio of each image effect. By moving a third indicator  1191 , the user may adjust the region occupied by each of the first, second and third image effects  1121 ,  1122  and  1123 . Based on sizes of such regions, the electronic device  101  may adjust the combining ratio among the first, second and third image effects  1121 ,  1122  and  1123 . This UI  1190  is, however, exemplary only and not to be construed as a limitation. 
       FIGS. 12A and 12B  are diagrams illustrating other examples of combining three or more image effects in an electronic device according to various example embodiments of the present disclosure. 
     As illustrated in part (a) of  FIG. 12A , the electronic device  101  may display an image  1210  on the display  420  and also display an image effect list  1220  that is applicable to the image  1210 . According to various embodiments, the electronic device  101  may dispose the image effect list  1220  horizontally at the bottom of the display  420 . The electronic device  101  may display the image effect, selected by the user, distinctively from the unselected image effects. 
     When the first image effect  1221  is selected by the user, the electronic device  101  may display a bar-shaped first UI  1230  for adjusting a level of applying the selected first image effect  1221  to the image  1210 . Further, the electronic device  101  may display a first indicator  1231  located in the first UI  1230  to adjust the level and also display a name of the selected image effect. While dragging the first indicator  1231 , the user may adjust the applied level of the selected image effect. 
     In this state, the user may select any other image effect to be combined with the preselected first image effect  1221 , and may also adjust the combining ratio between the first image effect  1221  and the selected image effect. 
     As illustrated in part (b) of  FIG. 12A , the electronic device  101  may display two marks  1211  and  1212  for indicating that two image effects  1221  and  1222  are selected by the user. After the image effects  1221  and  1222  are selected by the user, the electronic device  101  may display a second UI  1240  for adjusting the combining ratio of the second image effect  1222 . 
     For example, the electronic device  101  may further display the second UI  1240  having the same bar shape as the first UI  1230  previously displayed for indicating the applied level of the first image effect  1221 . The second UI  1240  may have a second indicator  1241 . In this case, the user may adjust the combining ratio between the first and second image effects  1221  and  1222  by moving the first and second indicators  1231  and  1241 . 
     As illustrated in part (c) of  FIG. 12A , the electronic device  101  may display three marks  1211 ,  1212  and  1213  for indicating that three image effects  1221 ,  1222  and  1223  are selected by the user. After the image effects  1221 ,  1222  and  1223  are selected by the user, the electronic device  101  may display a third UI  1250  for adjusting the combining ratio of the third image effect  1223 . 
     For example, the electronic device  101  may further display the third UI  1250  having the same bar shape as the first and second Uls  1230  and  1240  previously displayed for indicating the applied levels of the first and second image effects  1221  and  1222 . The third UI  1250  may have a third indicator  1251 . In this case, the user may adjust the combining ratio among the first, second and third image effects  1221 ,  1222  and  1223  by moving the first, second and third indicators  1231 ,  1241  and  1251 . 
     As illustrated in parts (a) and (b) of  FIG. 12B , the user may adjust the combining ratio among the first, second and third image effects  1221 ,  1222  and  1223  by moving the first, second and third indicators  1231 ,  1241  and  1251 . 
     As illustrated in part (a) of  FIG. 12B , the electronic device  101  may set the first and second image effects  1221  and  1222  at the same ratio and also set the third image effect  1223  at a greater ratio to combine the image effects  1221 ,  1222  and  1223 . As illustrated in part (b) of  FIG. 12B , the electronic device  101  may reduce the combining ratio of the second image effect  1222  from the previous ratio illustrated in part (a) of  FIG. 12B  and then combine the image effects  1221 ,  1222  and  1223 . Namely, the user may individually adjust the combining ratio of each of the image effects  1221 ,  1222  and  1223  from 0% to 100%. 
     According to various embodiments, the electronic device  101  may change continuously the image effects applied to the image  1210  displayed on the display  420 , based on the combining ratio among the image effects  1221 ,  1222  and  1223  being varying according to the movement of the indicators  1231 ,  1241  and  1251 . 
     As illustrated in part (c) of  FIG. 12B , the electronic device  101  may store the combined image effects, currently displayed on the display  420 , as a new image effect. The electronic device  101  may store the new image effect when a “save” tab  1260  displayed at the top of the display  420  is selected, or may store the new image effect in response to the third input as described in part (b) of  FIG. 9 . The electronic device  101  may add the newly stored image effect  1224  to the image effect list  1220 , and may display a suitable UI  1270  for adjusting a level of the new image effect  1224 .
