摘要:
A recording process records low-resolution video data while obtaining a high-resolution image in a window region being a portion of an entire image. Then, the process learns, as a resolution conversion rule, a resolution increasing parameter by using the high-resolution image. In a resolution increasing process, the resolution of the recorded low-resolution video data is increased by using the resolution increasing parameter learned in the recording process.

For a first region being a portion of a storage section (202), a read-out pulse produced by a progressive scanning shift register (206) is used to perform a progressive read-out operation of reading out signals from all rows of image-storing pixels (221). For a second region including an entire region other than the first region, a read-out pulse produced by a skip scanning shift register (205) is used to perform a skip read-out operation of reading out signals from intermittently-selected rows of image-storing pixels (221). The progressive scanning shift register (206) produces the read-out pulse so that the first region moves every frame and an entire region of the storage section (202) is scanned over a plurality of frames.

An exemplary 3D image shooting apparatus comprises: a polarized light source; an image capturing section that sequentially captures an image of the object that is being illuminated with each of plane polarized light rays, and an image processor. The image capturing section includes: a lens; an image sensor; and an incoming light transmitting section which has a transparent area and a plurality of polarization filter areas. The polarization filter areas are arranged outside of the transparent area, generally have a concentric ring shape, and include left and right filter areas so that their polarization transmission axis directions define an angle α (0

Provided is an image generation device generating a high-quality image of an object under a pseudo light source at any desired position, based on geometric parameters generated from a low-quality image of the object. The image generation device includes: a geometric parameter calculation unit that calculates a first geometric parameter regarding a shape of a surface from light source position, viewpoint position, and geometric normal information regarding the shape; a high-resolution database unit that stores an exemplum indicating a mesostructure of a portion of the surface and has a spatial resolution higher than the geometric normal information; an exemplum expansion unit that increases the exempla to be spatially expanded; a geometric parameter modification unit that modifies the first geometric parameter using the increased exempla; and an image generation unit that generates an output image by applying the modified geometric parameter to a reflection model.

In one embodiment, an element 106 transforms non-polarized light into plane polarized light with an arbitrary plane of polarization. A synchronizer 112 gives the element 106 an instruction to rotate the plane of polarization, thereby getting the plane of polarization of the illumination rotated and casting that polarized illumination toward the object. At the same time, the synchronizer 112 sends a shooting start signal to an image sensor 110, thereby getting video. The synchronizer 112 performs these processing steps multiple times. A captured video signal is sent to an image processing processor 108. Candidates for the azimuth angle of a surface normal are obtained based on an intensity maximizing angle image, the zenith angle of the surface normal is obtained based on a degree of intensity modulation image, and the ambiguity of the azimuth angle is solved, thereby generating a surface groove normal image.
