The digital photographing apparatus includes a photographing unit that generates photographed images from incident light, a live view generator that generates a live view image from the photographed images, and a display unit that displays the live view image. The live view generator determines the number of real-time photographed images to be combined, according to a set exposure time. The live view generator combines the real-time photographed images of the determined number to generate the live view image. The live view generator combines latest real-time photographed images of the determined number to update the live view image whenever a real-time photographed image is input. ## Claims ### Claim 1 A digital photographing apparatus comprising: a photographing unit that generates real-time photographed images from incident light; a live view generator that generates a live view image from the real-time photographed images; and a display unit that displays the live view image, wherein the live view generator determines a number of real-time photographed images to be combined, according to a set exposure time, combines the real-time photographed images of the determined number to generate the live view image, and combines latest real-time photographed images of the determined number, to update the live view image, whenever a real-time photographed image is input. ### Claim 2 (depends on 1) The digital photographing apparatus of claim 1, wherein the live view generator determines the number of real-time photographed images to be combined according to a frame rate of the live view image and the set exposure time. ### Claim 3 (depends on 1) The digital photographing apparatus of claim 1, further comprising a real-time image storage unit that stores a plurality of latest real-time photographed images. ### Claim 4 (depends on 1) The digital photographing apparatus of claim 1, wherein the live view generator performs an average combination of the real-time photographed images of the determined number to generate the live view image. ### Claim 5 (depends on 1) The digital photographing apparatus of claim 1, wherein the live view generator updates the number of real-time photographed images to be combined, when the set exposure time is changed. ### Claim 6 (depends on 1) The digital photographing apparatus of claim 1, further comprising an optical view finder that provides real-time images of incident light that is incident through a lens, an aperture, and a mirror, in an optical preview mode, wherein the live view generator provides the live view image in an exposure preview mode. ### Claim 7 (depends on 1) The digital photographing apparatus of claim 1, wherein the live view generator combines real-time photographed images that are currently stored, to generate the live view image, when the number of stored real-time photographed images is less than the determined number, and combines the stored real-time photographed images, to update the live view image, whenever the real-time photographed image is input and until the number of stored real-time photographed images reaches the determined number. ### Claim 8 A method of controlling a digital photographing apparatus, the method comprising: determining a number of real-time photographed images to be combined, according to a set exposure time; generating a live view image by combining the real-time photographed images of the determined number; and updating the live view image by combining latest real-time photographed images of the determined number, whenever a real-time photographed image is input. ### Claim 9 (depends on 8) The method of claim 8, wherein the determining of the number of real-time photographed images to be combined is performed according to a frame rate of the live view image and the set exposure time. ### Claim 10 (depends on 8) The method of claim 8, further comprising storing a plurality of latest real-time photographed images. ### Claim 11 (depends on 8) The method of claim 8, wherein the generating of the live view image comprises performing an average combination of the real-time photographed images of the determined number. ### Claim 12 (depends on 8) The method of claim 8, further comprising updating the number of real-time photographed images to be combined, when the set exposure time is changed. ### Claim 13 (depends on 8) The method of claim 8, further comprising: providing real-time images generated from incident light that is incident through a lens, an aperture, and a mirror on an optical view finder, in an optical preview mode; and providing the live view image in an exposure preview mode. ### Claim 14 (depends on 8) The method of claim 8, further comprising: generating the live view image by combining the real-time photographed images currently stored, if the number of the stored real-time photographed images is less than the determined number; and updating the live view image by combining the stored real-time photographed images whenever a real-time photographed image is input, until the number of stored real-time photographed images reaches the determined number. ### Claim 15 A non-transitory computer-readable recording medium having embodied thereon computer program codes for executing a method of controlling a digital photographing apparatus when being read and performed by a processor, the method comprising: determining a number of real-time photographed images to be combined, according to a set exposure time; generating a live view image by combining the real-time photographed images of the determined number; and updating the live view image by combining latest real-time photographed images of the determined number, whenever a real-time photographed image is input. ### Claim 16 (depends on 15) The non-transitory computer-readable recording medium of claim 15, wherein the determining of the number of real-time photographed images to be combined is performed according to a frame rate of the live view image and the set exposure time. ### Claim 17 (depends on 15) The non-transitory computer-readable recording medium of claim 15, wherein the method further comprises storing a plurality of latest real-time photographed images. ### Claim 18 (depends on 15) The non-transitory computer-readable recording medium of claim 15, wherein the generating of the live view image comprises performing an average combination of the real-time photographed images of the determined number. ### Claim 19 (depends on 15) The non-transitory computer-readable recording medium of claim 15, wherein the method further comprises updating the number of real-time photographed images to be combined, when the set exposure time is changed. ### Claim 20 (depends on 15) The non-transitory computer-readable recording medium of claim 15, wherein the method further comprises: providing real-time images generated from incident light that is incident through a lens, an aperture, and a mirror on an optical view finder, in an optical preview mode; and providing the live view image in an exposure preview mode.
