The display apparatus includes: a display unit, an image processing unit; an image receiving unit which receives an image from an image source; and a controller which controls the image processing unit to crop the image such that an aspect ratio of the received image becomes a preset reference aspect ratio and scale the cropped image in correspondence to a resolution of the display unit. With this configuration, an image with no distortion can be displayed. ## Claims ### Claim 1 A display apparatus including a display unit, comprising: an image processing unit; an image receiving unit which receives an image from an image source; a controller which controls the image processing unit to crop the received image to a single cropped image of a reference aspect ratio, scale the single cropped image according to a resolution of the display unit, and display the scaled single image as the image source on the display unit; and a non-volatile storing unit, wherein, when the image is received from the image source, the controller controls the image processing unit to crop the received image and stores the cropped image in the non-volatile storing unit, wherein size reduction of the received image to be stored in the non-volatile storing unit is performed by cropping the received image, wherein the received image comprises a plurality of vertically or horizontally continuous regions, and the cropping comprises selecting a first region and second region among the plurality of the vertically or horizontally continuous regions of the received image for deletion, wherein the first region and second region are discontinuous. ### Claim 2 (depends on 1) The display apparatus according to claim 1, wherein the image processing unit crops a width of the received image if the received image is a widthwise image and crops a length of the received image if the received image is a lengthwise image. ### Claim 3 (depends on 2) The display apparatus according to claim 2, wherein the image processing unit crops a left portion and a right portion of the received image at an equal first ratio if the width of the widthwise image is cropped and crops an upper portion and a lower portion of the received image at an equal second ratio if the length of the lengthwise image is cropped. ### Claim 4 (depends on 1) The display apparatus according to claim 1, further comprising a user selecting unit which allows a user to select a portion of the received image to be cropped. ### Claim 5 (depends on 1) The display apparatus according to claim 1, further comprising a user interface generating unit which superimposes a frame having the reference aspect ratio on the received image and moves the frame according to an input from a user. ### Claim 6 (depends on 1) The display apparatus according to claim 1, wherein the reference aspect ratio comprises an aspect ratio of the display unit. ### Claim 7 (depends on 1) The display apparatus according to claim 1, wherein the received image comprises a still image. ### Claim 8 A control method of a display apparatus including a display unit, comprising: receiving an image from an image source; determining whether an aspect ratio of the received image is a reference aspect ratio; cropping the received image to a single cropped image of the reference aspect ratio; displaying the single cropped image as the image source on a display; and storing the cropped image in a non-volatile storing unit, wherein size reduction of the received image to be stored in the non-volatile storing unit is performed by cropping the received image, wherein the received image comprises a plurality of vertically or horizontally continuous regions, and the cropping comprises selecting a first region and second region among the plurality of the vertically or horizontally continuous regions of the received image for deletion, wherein the first region and second region are discontinuous. ### Claim 9 (depends on 1) The display apparatus according to claim 1, wherein the controller controls the image processing unit to crop the received image to the single cropped image of the reference aspect ratio of the display unit. ### Claim 10 (depends on 1) The display apparatus according to claim 1, wherein the received image comprises a plurality of vertically continuous regions, and the cropping comprises selecting a plurality of discontinuous regions of the plurality of the vertically continuous regions of the received image for deletion. ### Claim 11 (depends on 8) The control method according to claim 8, wherein the cropping the received image comprises cropping a width of the received image if the received image is a widthwise image and cropping a length of the received image if the received image is a lengthwise image. ### Claim 12 (depends on 11) The control method according to claim 11, wherein the cropping the image comprises cropping a left portion and a right portion of the received image at an equal first ratio if the width of the widthwise image is cropped and cropping an upper portion and a lower portion of the received image at an equal second ratio if the length of the lengthwise image is cropped. ### Claim 13 (depends on 8) The control method according to claim 8, further comprising selecting by a user a portion of the received image to be cropped. ### Claim 14 (depends on 8) The control method according to claim 8, further comprising: superimposing a frame having the reference aspect ratio on the received image; and moving the frame according to an input from a user, wherein the cropping the received image comprises cropping the received image according to the moved frame. ### Claim 15 (depends on 8) The control method according to claim 8, further comprising scaling the cropped image according to a resolution of the display unit. ### Claim 16 (depends on 8) The control method according to claim 8, wherein the reference aspect ratio comprises an aspect ratio of the display unit. ### Claim 17 (depends on 8) The control method according to claim 8, wherein the cropping the received image comprises cropping off sides of the received image if the aspect ratio of the received image is larger than the reference aspect ratio and cropping off a top portion and a bottom portion of the received image if the aspect ratio of the received image is less than the reference aspect ratio, and each of the aspect ratio of the received image and the reference aspect ratio being indicative of corresponding horizontal image length to corresponding vertical image length. ### Claim 18 A method of displaying an image on a portable device, the method comprising: receiving an image; comparing the aspect ratio of the received image with an aspect ratio of a display unit of the portable device; if the aspect ratio of the received image is not equal to the aspect ratio of the display unit, removing a section of the received image to generate a single resultant image having the aspect ratio of the display unit, scaling the single resultant image, displaying the single resultant image as the image source on the display unit; and storing the scaled image in a non-volatile storage unit of the portable device, wherein size reduction of the received image to be stored in the non-volatile storing unit is performed by cropping the received image, wherein the received image comprises a plurality of vertically or horizontally continuous regions, and the cropping comprises selecting a first region and second region among the plurality of the vertically or horizontally continuous regions of the received image for deletion, wherein the first region and second region are discontinuous. ### Claim 19 (depends on 18) The method of claim 18, wherein the removing comprises: selecting by a user, a portion of the received image and one of deleting the selected portion or keeping the selected portion to generate the resultant image. ### Claim 20 (depends on 18) The method according to claim 18, wherein the received image comprises a plurality of regions, and the removing comprises selecting a plurality of discontinuous regions of the plurality of regions of the received image for deletion. ### Claim 21 (depends on 20) The display apparatus according to claim 20, wherein the plurality of regions are along a same plane.
