摘要： An apparatus for printing video images is disclosed. First the percentage of backlighting or people in the image is detected. That is, the probability of the presence of backlighting or people is detected. Then, the density gradation table is modified based on the detection result, and the presence of backlighting or the presence of people in the image is evaluated based on optical information, to select the best density gradation table from among plural density gradation tables, or to synthesize the best density gradation table. A luminance table is generated using the optimized density gradation table, and gradation correction of the image is then accomplished using that luminance table.

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.
