Provided are a panel member having good aesthetic properties and good visual recognition of characters, figures, symbols, and the like, and an electronic musical instrument having the panel member. An operation panel has a base layer (341) including a transmission portion (341a) that transmits visible light and is shaped like an identification (I), and a base portion (341b) that surrounds the transmission portion (341a) and has a lower transmittance of visible light than the transmission portion (341a); a first color-developing layer (342) that is positioned at a higher layer than the base layer (341), is formed of a certain color, and transmits at least a portion of visible light; a diffuse reflection layer (343) that is positioned at a higher layer than the first color-developing layer (342) and diffusely reflects at least a portion of visible light; and a second color-developing layer (344) that is positioned at a higher layer than the diffuse reflection layer (343) or inside the diffuse reflection layer (343) and is formed inside the shape of the identification (I) of the transmission portion (341a) when viewed from above.

In an image forming apparatus where two light beam scanning devices are arranged in the scanning direction for each color, the present invention provides an image forming apparatus that can eliminate extra sensors and reduce costs. [Solution] The system includes a correction means that corrects the positional misalignment for each optical writing means by forming correction patterns for each color on a second image carrier and detecting the correction patterns with a plurality of sensors, wherein the divided region and the boundary of the divided region are provided with a region width that is irradiated with a light beam by two adjacent optical writing means, and the region width overlaps by a certain distance only at the edges of the scanning regions of the two adjacent optical writing means, and within the region width, each optical writing means generates the correction pattern, and a common sensor detects the correction pattern of each optical writing means.

The present invention provides a latent image print in which a printed image is formed by combining a first image formed with a luminous colorant and a second image formed with a colored colorant of the same hue, and in which the image visible changes depending on the viewing angle, and the image change effect is clear. [Solution] The invention comprises a first image formed from a luminous colorant and a second image formed from a colored colorant of the same hue as the luminous colorant, wherein the first image is divided into an information section representing first significant information and a background section surrounding it, and the second image is formed by regularly arranged latent image elements representing second significant information, the background section and latent image elements are formed with visually equivalent colors, and the first image and the second image are fitted together.

A method of determining the concentration of an analyte in a sample of a body fluid with a mobile device having a camera is disclosed. The camera captures an image of a color reference card and of a reagent test field of an optical test strip having a sample applied to it. A predetermined pixel-based mean tone map correction is applied to the image obtained, which results in a first intensity-corrected image. Local brightness information is derived from the first intensity-corrected image. A mobile device-specific tone map correction is applied to the first intensity-corrected image, taking into account the local brightness information. A second intensity-corrected image is thereby obtained. Analyte concentration is determined based on a color formation reaction of the test field by using the second intensity-corrected image. Optionally, a color correction may be derived and applied to the second intensity-corrected image to obtain an intensity-corrected and color-corrected image.

The application provides a coating weather resistance verification method, a coating system and an automobile body part, and the method comprises the following steps: determining a corresponding coating system according to a selected coated substrate; using the coating system to adjust target automobile body colors according to the weather resistance requirements of different parts, and forming differentiated coating formulas; performing comprehensive performance tests on at least one target automobile body color, and obtaining the target color paste type used by the target automobile body color when the test is passed; obtaining the ratio of pigments to binders of the color paint layer in the test passed coating formula, and taking the maximum value in the ratio as the limit color base ratio; combining the coating of the coating system with the target color paste type, and adjusting according to the limit color base ratio, and performing weather resistance verification on the adjusted test coating. In this way, the weather resistance of the coating can be tested while ensuring that the stone impact resistance, scratch resistance, chemical resistance and other performances of the coating are not affected, the development cycle of the coating is greatly shortened, and the development efficiency is improved.
