The frame generator uses same image frames, which are used to produce one video reproduction frame, to produce another video reproduction frame. ## Claims ### Claim 1 An image processing apparatus, comprising: an imaging unit to photograph a subject a plurality of times to obtain a plurality of continuous image frames; an image feature controller to adjust image features of the obtained plurality of continuous image frames by controlling the imaging unit; a storage unit to store the obtained plurality of continuous image frames; and a frame generator to obtain a number of image frames from the stored plurality of continuous image frames and synthesize the obtained number of image frames to sequentially produce video reproduction frames, wherein the frame generator uses at least one image frame from the obtained number of image frames to produce at least two video reproduction frames to sequentially produce the video reproduction frames, and when a weight is respectively assigned to the number of image frames based on a brightness of the image frames, the frame generator changes the obtaining of the number of image frames according to the respectively assigned weight. ### Claim 2 (depends on 1) The image processing apparatus as claimed in claim 1, wherein the frame generator produces the video reproduction frames using the number of image frames in which at least one of an exposure amount, a depth of field, and a focus point which are image features is changed. ### Claim 3 (depends on 2) The image processing apparatus as claimed in claim 2, wherein the image feature controller adjusts the image features such that image features of the video reproduction frames are monotonously changed. ### Claim 4 (depends on 3) The image processing apparatus as claimed in claim 3, wherein the image feature controller adjusts the image features such that image features of the video reproduction frames are continuously changed. ### Claim 5 (depends on 3) The image processing apparatus as claimed in claim 3, wherein the image feature controller controls exposure amounts of the number of image frames by changing at least one among an exposure time, gain features, an aperture value, and a neutral density (ND) filter. ### Claim 6 (depends on 3) The image processing apparatus as claimed in claim 3, wherein the image feature controller controls the depths of field of the number of image frames by changing an aperture value. ### Claim 7 (depends on 3) The image processing apparatus as claimed in claim 3, wherein the image feature controller controls focus points of the number of image frames by controlling a focus lens included in the imaging unit. ### Claim 8 (depends on 4) The image processing apparatus as claimed in claim 4, wherein the image feature controller controls exposure amounts of the number of image frames by changing at least one among an exposure time, gain features, an aperture value, and a neutral density (ND) filter. ### Claim 9 (depends on 4) The image processing apparatus as claimed in claim 4, wherein the image feature controller controls the depths of field of the number of image frames by changing an aperture value. ### Claim 10 (depends on 4) The image processing apparatus as claimed in claim 4, wherein the image feature controller controls focus points of the number of image frames by controlling a focus lens included in the imaging unit. ### Claim 11 (depends on 1) The image processing apparatus as claimed in claim 1, wherein, when image information is changed between the number of image frames to exceed a threshold, the frame generator suspends production of the video reproduction frame. ### Claim 12 (depends on 1) The image processing apparatus as claimed in claim 1, further comprising a reproduction unit to reproduce the video reproduction frames. ### Claim 13 An image processing method, comprising: photographing a subject a plurality of times to obtain a plurality of continuous image frames; adjusting image features of the obtained plurality of continuous image frames; storing the obtained plurality of continuous image frames; and obtaining a number of image frames from the stored plurality of continuous image frames, and synthesizing the obtained number of image frames to sequentially produce video reproduction frames, wherein the producing of the video reproduction frames comprises using at least one image frame from the obtained number of image frames to produce at least two video reproduction frames to sequentially produce the video reproduction frames, and when a weight is respectively assigned to the number of image frames based on a brightness of the image frames, changing the obtaining of the number of image frames according to the respectively assigned weight. ### Claim 14 A non-transitory computer readable recording medium having stored a program code therein to be executed in a computer, wherein a method performed using the program code comprises: photographing a subject a plurality of times to obtain a plurality of continuous image frames; adjusting image features of the obtained plurality of continuous image frames; storing the obtained plurality of continuous image frames; and obtaining a number of image frames from the stored plurality of continuous image frames, and synthesizing the obtained number of image frames to sequentially produce video reproduction frames, wherein the producing of the video reproduction frames comprises using at least one image frame from the obtained number of image frames to produce at least two video reproduction frames to sequentially produce the video reproduction frames, and when a weight is respectively assigned to the number of image frames based on a brightness of the image frames, changing the obtaining of the number of image frames according to the respectively assigned weight.
