사면 카메라를 이용한 고선명 영상획득 계산영상법

Non-frontal cameras have an image sensor that is intentionally slanted compared to the lens. Because the sensor and the lens are not parallel, the sharp focus plane of the camera is also slanted with variable object distance on the plane according to the lens's law. In this study, we propose a high-definition image-acquisition method that uses a non-frontal camera. A series of images are obtained by rotating the non-frontal camera about an optical axis, and each of the images has a sharp focus plane of variable object distance. We can compose a sharp focus image by selecting focused pixels among the series of images according to a focus measure. The initial results of the non-frontal camera and further work to compose high-definition images are presented in this study.
