A flame retardant resin composition, containing a thermoplastic resin and a flame retardant, wherein the flame retardant contains a nitrogen-containing structure-introduced phosphorylated lignin derivative, wherein the nitrogen-containing structure-introduced phosphorylated lignin derivative is produced by introducing a nitrogen-containing structure into a lignin derivative and adding a phosphoric acid to the lignin derivative, or by adding a phosphoric acid to a lignin derivative and introducing a nitrogen-containing structure into the lignin derivative, or by introducing a nitrogen-containing structure into and adding a phosphoric acid to a lignin derivative simultaneously, and wherein the lignin derivative is obtained by subjecting a naturally occurring lignin to a treatment for allowing the naturally occurring lignin to be decomposed into small molecules or to be water-soluble.

Systems and methods for space-time video montage are described. In one aspect, one or more arbitrary space-time volumes representing informative video portion(s) of at least one input video data sequence are identified. A video summary representing a montage of the at least one input video data sequence is generated for presentation to user from the one or more arbitrary space-time volumes.

Technologies that enable correcting for the non-linear relationship between scene irradiance and digital pixel intensity values of an image of the scene produced by a camera. Imaging noise is used as a signal from which a corrective function is derived. Noise distributions from the image are evaluated to determine the radiometric response function of the camera, from which an inverse response function is computed and used for calibration.

Surfaces can be decorated with texture tiling and/or texture painting using one or more sample textures, such as BTFs. In a described implementation of texture tiling, a patch-based BTF synthesis algorithm is utilized. In an example embodiment, a mesh of a target surface is re-sampled to produce a dense mesh such that there is a one-to-one correspondence between vertices of the dense mesh and pixels of an image. Patch matching is then employed with a working image that corresponds to a working patch. In an example embodiment, the patch matching is effectuated using translations and rotations of the sample texture. In a described implementation of texture painting, irregular feature(s) of a sample texture are synthesized onto a target surface. In an example embodiment, user-specified constraints as to a desired foreground feature of a sample texture and an intended foreground region of a targeted surface are factored into a graphcut operation.

An optical disk recording/reproduction apparatus includes a semiconductor laser, an objective lens provided opposite an optical disk, an optical system for supplying a laser beam from the semiconductor laser to the objective lens, an aperture for not intercepting the laser beam in reproducing from a digital video disk and intercepting an outermost portion of the laser beam in reproducing from a compact disk, and a tracking servo mechanism for moving the objective lens in a tracking direction orthogonal to the running direction of a track of the optical disk. The aperture has an oblong opening that is longer in the tracking direction than in the track running direction.

A method of calibrating a brightness value measured by a camera with an amount of light received by the camera includes creating a series of measurements, wherein for each measurement the amount of light received at an image plane in the camera is controlled to be a known ratio of two opposed irradiance values: a high irradiance value and a low irradiance value. Each ratio is correlated with the brightness value measured by the camera. A function is obtained describing the correlation.

A Poisson-quantization noise model for modeling noise in low-light conditions is described. In one aspect, image information is received. A Poisson-quantization noise model is then generated from a Poisson noise model and a quantization noise model. Poisson-quantization noise is then estimated in the image information using the Poisson-quantization noise model.

Described is a technology in which a collage of digital photographs is dynamically computed and rendered so as to vary the photographs that are visible in the collage over time. A dynamic collage mechanism coupled to a source of photographs computes a collage for visible output, and dynamically updates the collage on a scheduled basis by adding different photograph(s) in place of other photograph(s). Each arrangement of the photographs in each updated collage is computed from a previous collage. Also described is layout optimization in which the photographs in the updated collage are translated, rotated and/or layered so as to cover a maximum amount of the overall area of the collage.
