An electronic camera is provided with an image-capturing device for photographing (73, 26) that captures an image of a subject image passed through a taking lens and outputs image data, an image-capturing device for scene analysis (86) that is provided at a position conjugate with the position of the image-capturing device for photographing relative to the taking lens and outputs scene analysis image data by receiving the light of the subject image and a scene detection processing circuit (35) that determines a white balance adjustment gains based upon the scene analysis image data output by the analytical image-capturing device. Using the white balance adjustment gains determined by the scene detection processing circuit, white balance adjustment is performed on the image data output by the image-capturing device for photographing.

The invention discloses an adaptive colour image processing method and an adaptive colour image processing system. The method comprises the following steps of: reading an image to be processed; carrying out overall adaptive transformation on the luminance component of the image to be processed through a non-linear inverse S-type function to obtain an overall luminance enhancement image; regulating the local contrast ratio of the overall luminance enhancement image according to the corresponding relation between the central pixel luminance and the neighborhood pixel luminance of the overall luminance enhancement image to obtain a local luminance enhancement image; and carrying out linear colour restoration on the image to be processed according to the ratio between the luminance components of the local luminance enhancement image and the image to be processed to obtain a colour enhancement image. By the method and through the system of the invention, the luminance of the image to be processed can be adaptively regulated; the contrast ratio of a back area and a bright area is enhanced at the same time; the local contrast ratio of the image to be processed can be effectively enhanced; the over-enhancement phenomenon generated at the edge of the image is inhibited; the colour of the image is well kept; and better enhancement effect is achieved.

Digital reactive dye printing process for mulberry silk fabric

The invention provides a digital reactive dye printing process for a mulberry silk fabric. The process comprises the following steps: carrying out textile sizing, drying, carrying out jet printing, steaming, washing by cold water, washing by hot water, washing by soap, washing by hot water, washing by cold water, and drying, wherein a sizing agent used in the textile sizing step comprises the following components in percentage by weight: 1%-3% of sodium sulfate powder, 0.5%-1% of sodium alginate, 3%-5% of urea, 0.5%-1.5% of sodium hydrogen carbonate, 1%-2% of modified starch, 5%-7% of electrolyte and the balance being water. By virtue of the process, the digital printing color yield of the mulberry silk fabric is increased, the inkjet printing color depth on a textile is increased, the color difference between a pattern on the textile and an electronic pattern is reduced, and the hand feel of the fabric is good.

A decoration cover plate and a touch panel having the decoration cover plate are provided. The decoration cover plate includes a substrate having an appearance decoration layer, an auxiliary light-shielding layer and a buffer layer stacked thereon. The buffer layer is disposed between the appearance decoration layer and the auxiliary light-shielding layer. The auxiliary light-shielding layer and the appearance decoration layer are opposite to each other. The touch panel further includes a touch-sensing element and a plurality of transmission lines. The touch-sensing element is disposed on the substrate and at least located within a transparent region of the touch panel. The transmission lines are disposed at a side of the auxiliary light-shielding layer far away from the substrate and electrically connected to the touch-sensing element.

Semi-inverse method-based rapid single image dehazing algorithm

The invention discloses a semi-inverse method-based rapid single image dehazing algorithm, which comprises the following steps: In light of an atmospheric scattering model, working out an atmospheric global illumination value by utilizing an improved semi-inverse algorithm, wherein the robustness of the obtained atmospheric global illumination value is stronger than that of the maximum gray value in a dark channel; secondly, fusing the edge information and the scene depth information of an image upon the characteristic of atmospheric scattered light by taking the edge information of the image as a synthesis condition, and accurately estimating an atmospheric streamer; then, obtaining an initial restored haze-free image according to the atmospheric scattering model; finally, performing color adjustment and detail enhancement processing on the image after being initially dehazed to obtain a haze-free image with strong sense of reality. The semi-inverse method-based rapid single image dehazing algorithm has a very good processing effect on depth mutation or prospect pixels, so that a vignetting effect is eliminated; shown by a large number of experiments, the semi-inverse method-based rapid single image dehazing algorithm disclosed by the invention is capable of well keeping color and detail information, is better in automaticity and robustness, and can be further used for a video dehazing system.

Optical Filter and Lighting Apparatus

An optical filter and a lighting device using the same wherein the suppression of the melatonin secretion by the reception of light in the nighttime is prevented and the color of light is maintained desirable are provided. The optical filter has a mean transmissivity of a light beam in a wavelength range of about 480˜550 nm is about 30% or less. The optical filter is formed by at least molding a transparent resin and a resin composition material containing an orange color series fluorescent dye material, and, for 100 weight part of the transparent resin, the resin composition material containing about 0.005˜0.2 weight part of the orange color series fluorescent dye material is molded. This can prevent the suppression of the melatonin secretion in the nighttime. The color of light is maintained desirable. The optical filter may be applied to a lighting apparatus.
