摘要： A polarization camera that can capture polarization images and a color image at the same time is used. Specifically, a clear sky polarization image, which provides information about the polarization of a part of the sky, is captured by a clear sky polarization image capturing section 100. And by reference to the information provided by a sun position determining section 1301 that determines the sun's position at the time of shooting, a camera direction estimating section 101 determines in what direction and in what area of the whole sky the clear sky polarization image is located as a polarization pattern. Finally, information about what direction or orientation on the globe the camera (image capture device) is now facing is output. In this manner, the direction of the camera and the relative position of the camera with respect to the sun can be known without providing a sensor separately and without capturing the whole sky or the sun.

摘要： An image processor (101) according to a preferred embodiment of the present invention includes a polarized light source (102) and a polarization camera ( 103 ). In shooting an object (104), the object is irradiated with polarized light (105) that rotates its polarization plane. The polarized light is reflected from the object's surface and the polarized reflected light (106) reaches the polarization camera ( 103 ), thereby recording an image there. The polarization camera (103) includes a polarization image sensor (201), an intensity and polarization information processing section (202), a polarization plane control section (204), and an image capturing control section ( 205 ). By capturing an image every time the polarization plane control section (204) changes the polarization state of the polarized light, an intensity image Y and a polarization phase image P are obtained in association with each polarization state. Using these images, a resolution increasing processing section (203) generates a high-resolution normal image (208) and a high resolution intensity image (209).
