연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

A digital camera 1 includes an image composition unit 52 and a composite position determining unit 53. The image composition unit 52 acquires a plurality of images which have been captured continuously. The composite position determining unit 53 sets candidate areas for determining composite positions in adjacent images, from the plurality of images acquired by the composite position determining unit 52. Furthermore, the composite position determining unit 53 determines composite positions of the adjacent images based on a degree of similarity between th...

1. An image processing apparatus including a central processing unit (CPU) which is operable to function as units comprising: an acquiring unit that acquires a plurality of images which have been captured continuously;a common area setting unit that sets a first common area in a first image from among the plurality of images acquired by the acquiring unit, and sets a second common area in a second image from among the plurality of images acquired by the acquiring unit, wherein the first and second common areas include imaging contents common to both of the first and second images;a line setting unit that sets a plurality of first lines in the first common area and sets a plurality of second lines in the second common area, the lines being set in the first and second areas regardless of imaging contents of the first and second common areas;a calculation unit that calculates a similarity by comparing (i) one of the plurality of first lines set in the first common area and (ii) one of the plurality of second lines set in the second common area that corresponds to the one of the plurality of first lines, for each of the plurality of first lines set in the first common area;a selection unit that selects a pair of lines from among the lines set in the first and second common areas by the line setting unit, based on the similarity calculated by the calculation unit; anda composite unit that combines the first image and the second image such that the pair of lines selected by the selection unit are combined,wherein:the plurality of first lines set in the first common area and the plurality of second lines set in the second common area are straight lines which extend parallel to each other in a direction perpendicular to a direction in which the first and second images are to be combined, all of the lines set in the first and second common areas having a same predetermined shape and area, andthe plurality of first lines are set side by side in the first common area at a fixed distance apart from one another, and the plurality of second lines are set side by side in the second common area at a fixed distance apart from one another. 2. The image processing apparatus as set forth in claim 1, wherein the common area setting unit sets at least one of a length, a width, and a position of each of the first and second common areas. 3. The image processing apparatus as set forth in claim 1, further comprising an image capturing unit, wherein the acquiring unit acquires the plurality of images, each having a first angle of view, by sequentially performing image capturing by the image capturing unit at predetermined time intervals. 4. The image processing apparatus as set forth in claim 1, wherein the first and second common areas are sets of pixels. 5. The image processing apparatus as set forth in claim 1, wherein the selection unit selects the pair of lines having a highest similarity from among the lines set in the first and second common areas. 6. The image processing apparatus as set forth in claim 1, wherein the CPU is operable to further function as units comprising: a composite image generating unit that generates a panoramic image based on the first and second images combined by the composite unit; anda recording control unit that performs control to record the panoramic image in a recording medium. 7. The image processing apparatus as set forth in claim 1, further comprising a detecting unit that detects the first and second common areas. 8. The image processing apparatus as set forth in claim 1, wherein: each of the plurality of first lines set in the first common area extends from a first end of the first common area to a second end of the first common area, andeach of the lines set in the second common area extends from a first end of the second common area to a second end of the second common area. 9. An image processing method of an image processing apparatus having an acquiring unit that acquires a plurality of images which have been captured continuously, the method comprising: setting a first common area in a first image from among the plurality of images acquired by the acquiring unit, and setting a second common area in a second image from among the plurality of images acquired by the acquiring unit, wherein the first and second common areas include imaging contents common to both of the first and second images;setting a plurality of first lines in the first common area and setting a plurality of second lines in the second common area, the lines being set in the first and second areas regardless of imaging contents of the first and second common areas;calculating a similarity by comparing (i) one of the plurality of first lines set in the first common area and (ii) one of the plurality of second lines set in the second common area that corresponds to the one of the plurality of first lines, for each of the plurality of first lines set in the first common area;selecting a pair of lines from among the lines set in the first and second common areas, based on the similarity calculated in the calculating; andcombining the first image and the second image such that the pair of lines selected in the selecting are combined,wherein:the plurality of first lines set in the first common area and the plurality of second lines set in the second common area are straight lines which extend parallel to each other in a direction perpendicular to a direction in which the first and second images are to be combined, all of the lines set in the first and second common areas having a same predetermined shape and area, andthe plurality of first lines are set side by side in the first common area at a fixed distance apart from one another, and the plurality of second lines are set side by side in the second common area at a fixed distance apart from one another. 10.
