360 results about "Color intensity" patented technology

Color intensity refers to how bright or dull a color looks, according to Art Studio Chalkboard. This term is most often used in art and photography but can also have other applications. Bright colors are considered more pure, while dull colors can appear indistinguishable or gray. Saturation, chroma and chromacity are used to describe color intensity in art.

Three-dimensional object molding apparatus and method

InactiveUS20020167101A1Facilitate short-time low-cost moldingShort-time low-cost coloringConfectioneryPattern printingShell moldingColor intensity
In a 3D object molding apparatus (10), a tank (18d) holds an uncolored or white resin as a first material for use in interior molding, and tanks (18a to 18c) hold colored resins as second materials for use in surface molding. These resin materials are jetted from injection nozzles (15a to 15d) in the direction of a stage (20). A drive control unit (12) serving as control means moves a nozzle head (15) in the XY plane and controls jets of resin materials from the injection nozzles (15a to 15d). In the interior molding of a 3D molded product (21), at least the first material is jetted, while in the surface molding, at least the second materials are jetted. The injection nozzles (15a to 15c) are coloring nozzles to jet colored resins in molding color portions of the 3D molded product, and the injection nozzle (15d) is a molding nozzle to jet an uncolored molding resin in molding the other portions. The apparatus 10 provided with the coloring nozzles to jet predetermined coloring agents such as colored resins can jet coloring agents from the coloring nozzles in molding the 3D molded product, thereby achieving coloring of the 3D molded product in the molding process. Further, the use of a white resin allows representation of blight colors that are not available only with three colors (Y, M, C), thereby permitting reproduction of the color intensity and gradations in the coloring of the 3D molded product (21) in the molding process.

Method for characterizing color of characteristic tobacco by place of origin

ActiveCN101762583AReflect regional characteristicsImage analysisColor measuring devicesColor intensityDigital image
The invention provides a method for characterizing the color of characteristic tobacco by place of origin. The method is characterized by comprising the following steps: statistically regarding the random distribution of colors on the surface of tobacco as a fractal structure, and acquiring the high-accuracy digital image of the tobacco and carrying out the background removing and segmenting treatment; calculating the fractal dimensions corresponding to different threshold parameters of each color intensity (red, green, blue and luminance) of the tobacco, taking the fractal dimensions as the indexes for describing the distribution of the colors on the surface of tobacco on a quantified basis, and plotting the fractal dimension variation curve of each color intensity, which can reflect the distribution of the colors on the surface of the tobacco on an overall basis; and characterizing the color of characteristic tobacco by place of origin by using the fractal dimension variation curve. The method for establish the characterization of the color of the tobacco can reflect the characteristics of spatial distribution of colors and include the characteristic of accumulation. The fractal dimension variation curve can reflect the distribution of the colors on the surface of the tobacco on an overall basis, thereby reflecting the provincial characteristics in the color expression of the tobacco in different places of origin in China.

Automatic exposure method and mobile terminal

ActiveCN105827990AScience Exposure SettingsAccurate Auto ExposureTelevision system detailsColor television detailsColor intensityLightness
The present invention provides an automatic exposure method applied to a mobile terminal. The mobile terminal includes a color camera and a black-and-white camera. The automatic exposure method comprises the steps of obtaining the color image of the color camera and the black-and-white image of the black-and-white camera, wherein the two images are acquired synchronously; calculating the color intensity value of the color image and the black-and-white intensity value of the black-and-white image; according to the color intensity value of the color image and the black-and-white intensity value of the black-and-white image, adjusting the exposure parameters of the color camera; according to the adjusted exposure parameters of the color camera, controlling the exposure of the color camera. The present invention also provides a corresponding mobile terminal. Based on the automatic exposure method of the present invention, the exposure parameters of the color camera can be adjusted based on the combination of the color camera and the black-and-white camera, so that the exposure setting for the current scene can be configured more scientifically. The more accurate exposure is realized. Therefore, the problem in the prior art that the color camera is small in dynamic range so as to cause the overexposure/over-dark condition of the local region of a photographed image can be effectively solved.
