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.

An improved system and method for providing information concerning the level of focus of objects appearing on a viewfinder for a digital camera system. The present invention analyzes a plurality of objects or regions of an image that is being shown to a user through a viewfinder of an electronic device. The system creates an overview map that matches the objects within the image, and colors are applied to objects within the overview map, representing the focus quality levels of the respective objects. The overview map is superimposed over the image, prov...

What is claimed is: 1. A method for providing a user with focus information for an image, comprising: identifying an image for potential capture by a camera module; identifying a plurality of objects within the image; analyzing the plurality of objects to determine the level of focus for each of the plurality objects; assigning colors to the plurality of objects based upon the level of focus for each object, wherein the colors are assigned to the plurality of objects based upon predefined criteria; exhibiting the image with the assigned colors being exhibited in conjunction with their respective objects; and creating a transparent overview map that is substantially identical to the image. 2. The method of claim 1, wherein the predefined criteria comprises a plurality of predetermined focus quality ranges, and wherein each predetermined focus quality range is assigned a particular color. 3. The method of claim 1, wherein the assigned colors are exhibited in a translucent form such that both the colors and their associated objects are viewable at the same time. 4. The method of claim 1, further comprising: applying the colors to the image in the locations of the overview map that correspond to the respective objects, wherein, when the image and the colors are exhibited, the overview map including the colors is superimposed on the image during exhibition. 5. The method of claim 1, wherein the camera module is incorporated into a mobile telephone. 6. The method of claim 1, wherein the exhibition occurs on a viewfinder operatively connected to the camera module. 7. The method of claim 1, further comprising, upon the level of focus of at least one of the plurality of objects being altered, reassigning the colors to the plurality of objects based upon predefined criteria to reflect the alteration of the respective focus levels; and exhibiting the image with the assigned colors being exhibited in conjunction with their respective objects to reflect the alteration of the respective focus levels. 8. A computer program product, embodied on a computer-readable medium, for providing a user with focus information for an image, comprising: computer code for identifying an image for potential capture by a camera module; computer code for identifying a plurality of objects within the image; computer code for analyzing the plurality of objects to determine the level of focus for each of the plurality objects; computer code for assigning colors to the plurality of objects based upon the level of focus for each object, wherein the colors are assigned to the plurality of objects based upon predefined criteria; computer code for exhibiting the image with the assigned colors being exhibited in conjunction with their respective objects; and computer code for creating a transparent overview map that is substantially identical to the image. 9. The computer program product of claim 8, wherein the predefined criteria comprises a plurality of predetermined focus quality ranges, and wherein each predetermined focus quality range is assigned a particular color. 10. The computer program product of claim 8, wherein the assigned colors are exhibited in a translucent form such that both the colors and their associated objects are viewable at the same time. 11. The computer program product of claim 8, further comprising: computer code for applying the colors to the image in the locations of the overview map that correspond to the respective objects, wherein, when the image and the colors are exhibited, the overview map including the colors is superimposed on the image during exhibition. 12. The computer program product of claim 8, wherein the camera module is incorporated into a mobile telephone. 13. The computer program product of claim 8, wherein the exhibition occurs on a viewfinder operatively connected to the camera module. 14. The computer program product of claim 8, further comprising, computer code for, upon the level of focus of at least one of the plurality of objects being altered, reassigning the colors to the plurality of objects based upon predefined criteria to reflect the alteration of the respective focus levels; and computer code for exhibiting the image with the assigned colors being exhibited in conjunction with their respective objects to reflect the alteration of the respective focus levels. 15. An electronic device, comprising: a camera module; a processor operatively connected to the camera module; and a memory unit operatively connected to the processor and including: computer code for identifying an image for potential capture by the camera module; computer code for identifying a plurality of objects within the image; computer code for analyzing the plurality of objects to determine the level of focus for each of the plurality objects; computer code for assigning color to the plurality of objects based upon the level of focus for each object, wherein the colors are assigned to the plurality of objects based upon predefined criteria; computer code for exhibiting the image with the assigned colors being exhibited in conjunction with their respective objects; and computer code for creating a transparent overview map that is substantially identical to the image. 16. The electronic device of claim 15, wherein the predefined criteria comprises a plurality of predetermined focus quality ranges, and wherein each predetermined focus quality range is assigned a particular color. 17. The electronic device of claim 15, wherein the assigned colors are exhibited in a translucent form such that both the colors and their associated objects are viewable at the same time. 18. The electronic device of claim 15, wherein the memory unit further comprises computer code for: applying the colors to the image in the locations of the overview map that correspond to the respective objects, wherein, when the image and the colors are exhibited, the overview map including the colors is superimposed on the image during exhibition. 19. The electronic device of claim 15, wherein the camera module is incorporated into a mobile telephone. 20. The electronic device of claim 15, wherein the memory unit further comprises: computer code for, upon the level of focus of at least one of the plurality of objects being altered, reassigning the colors to the plurality of objects based upon predefined criteria to reflect the alteration of the respective focus levels; and computer code for exhibiting the image with the assigned colors being exhibited in conjunction with their respective objects to reflect the alteration of the respective focus levels.
