    摘要: 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.

    摘要: 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.
