The present invention includes enabling an AoC (always on camera) mode for maintaining a state for a camera to capture an image, obtaining a shot input of capturing the image in the enabled AoC mode, and controlling the camera to capture the image instantly. ## Claims ### Claim 1 A terminal comprising: a touchscreen; a camera configured to capture an image; and a controller configured to: enable an AoC (always on camera) mode for maintaining a state for the camera to capture the image, control the state for the camera to capture the image to be maintained and display a shot button for capturing the image in the enabled AoC mode, control the camera to capture a first image in the AoC mode without displaying a preview image of the first image and display the captured first image in response to a first touch input to the displayed shot button, display a preview image of a second image and control the camera to capture the second image in the AoC mode without displaying the captured second image in response to a second touch input to the displayed shot button, and after capturing the first image, display a plurality of images including the first image which were captured in the AoC mode without displaying preview images of the plurality of images. ### Claim 2 (depends on 1) The terminal of claim 1, wherein the controller displays the preview image of the second image to be captured on at least a region of the touchscreen, and wherein when a pinch-in input is received in the course of displaying the preview image the AoC mode is enabled. ### Claim 3 (depends on 1) The terminal of claim 1, wherein the controller controls the touchscreen to display a screen of at least one launched application in the AoC mode. ### Claim 4 (depends on 1) The terminal of claim 1, wherein the shot button is located on a prescribed region of the touchscreen. ### Claim 5 (depends on 4) The terminal of claim 4, wherein the controller displays the shot button of an FAB (floating action button) type and wherein the controller displays the preview image of the second image to be captured by the camera on an inner region of the displayed shot button of the FAB type. ### Claim 6 (depends on 1) The terminal of claim 1, wherein the controller determines a quality of the captured image based on at least one selected from the group consisting of focus, brightness, color and blur of the captured image taken in the AoC mode and wherein if the determined quality is below a reference quality, the controller outputs a guide information on the image taken in the AoC mode. ### Claim 7 (depends on 1) The terminal of claim 1, wherein the controller determines a quality of the captured image based on at least one selected from the group consisting of focus, brightness, color and blur of the captured image taken in the AoC mode and wherein the controller provides a user interface for handling the image below a reference quality among captured images taken in the AoC mode. ### Claim 8 (depends on 7) The terminal of claim 7, wherein the controller displays the image below the reference quality among the captured images taken in the AoC mode on the touchscreen, wherein the controller displays a DELETE menu for deleting the image below the reference quality and a SAVE menu for saving the image below the reference quality, wherein if obtaining an input of selecting the displayed DELETE menu, the controller deletes the displayed image below the reference quality, and wherein if obtaining an input of selecting the displayed SAVE menu, the controller saves the displayed image below the reference quality. ### Claim 9 A method of operating a terminal, comprising: enabling an AoC (always on camera) mode for maintaining a state for a camera to capture an image and displaying a shot button for capturing the image on a touchscreen of the terminal; capturing a first image in the AoC mode without displaying a preview image of the first image and displaying the captured first image in response to a first touch input to the displayed shot button; displaying a preview image of a second image and capturing the second image in the AoC mode without displaying the captured second image in response to a second touch input to the displayed shot button; and after capturing the first image, displaying a plurality of images including the first image which were captured in the AoC mode without displaying preview images of the plurality of images. ### Claim 10 (depends on 9) The method of claim 9, further comprising the steps of: displaying a preview image of the second image to be captured on at least a region of the touchscreen, receiving a pinch-in input in the course of displaying the preview image; and enabling the AoC mode. ### Claim 11 (depends on 9) The method of claim 9, further comprising displaying a screen of at least one launched application in the AoC mode. ### Claim 12 (depends on 9) The method of claim 9, the displaying the shot button, comprising: displaying the shot button of an FAB (floating action button) type; and displaying the preview image of the second image to be captured by the camera on an inner region of the displayed shot button of the FAB type. ### Claim 13 (depends on 9) The method of claim 9, further comprising: determining a quality of the captured image based on at least one selected from the group consisting of focus, brightness, color and blur of the captured image taken in the AoC mode; and if the determined quality is below a reference quality, outputting a guide information on the image taken in the AoC mode. ### Claim 14 (depends on 9) The method of claim 9, further comprising: determining a quality of the captured image based on at least one selected from the group consisting of focus, brightness, color and blur of the captured image taken in the AoC mode; and providing a user interface for handling the image below a reference quality among captured images taken in the AoC mode. ### Claim 15 (depends on 14) The method of claim 14, the providing the user interface for handling the image below the reference quality, comprising: displaying the image below the reference quality among the captured images taken in the AoC mode; displaying a DELETE menu for deleting the image below the reference quality and a SAVE menu for saving the image below the reference quality; if obtaining an input of selecting the displayed DELETE menu, deleting the displayed image below the reference quality; and if obtaining an input of selecting the displayed SAVE menu, saving the displayed image below the reference quality.
