Spectral color matching to a device-independent color value

Methods, systems, and apparatus for mapping a nonspectral representation of a target color, such as an input color tuple, to a set of concentration values for a set of device-specific colorants. The invention includes using the input color tuple to derive a first set of colorant concentration values from a color lookup table; and refining the first set of colorant concentration values by an iterative non-linear process to generate a final set of colorant concentration values. The first set of colorant concentration values can derived by using an input color tuple as an index to obtain grid-point concentration values at two grid points of the color lookup table and calculating the first set of colorant concentration values as a linear interpolation of the grid-point concentration values. In an implementation that provides a color function table of color-additive function values, the iterative non-linear process can include iteratively (a) calculating an interim color tuple from an interim set of colorant concentration values and the color function table, the initial interim set of colorant concentration values being the first set of colorant concentration values, and (b) deriving an interim set of colorant concentration values from a difference between the input color tuple and the interim color tuple. The calculations can include calculating a partial derivative of an error function from the difference between the input color tuple and the interim color tuple; and using the partial derivative to derive a successor interim set of colorant concentration values from a current interim set of colorant concentration values.

Color function seasoning low-sodium liquid salt and preparing method thereof

The invention relates to a color function seasoning low-sodium liquid salt formula and a preparing method of color function seasoning low-sodium liquid salt. Low-sodium liquid salt mother liquor is used as main raw materials of the low-sodium liquid salt. The low-sodium liquid salt mother liquor comprises (according to the mass percent in the mother liquor salt content total quantity) 60%-80% of sodium chloride, 15%-30% of potassium chloride and 5%-15% of magnesium chloride. The low-sodium liquid salt further comprises a plant source function component with the adding quantity (according to the mass added into 100 mL of low-sodium liquid salt mother liquor) is 0.5%-10%. Optimization technologies such as mixing, homogenization, sterilization and filling are carried out, and color function seasoning low-sodium liquid salt products with function component activity being maintained to the maximum degree are prepared. A controllable-quantity liquid packaging container is used, the salt can be easily and evenly blended into food, the problem that solid salt is dissolved slowly, so that excessive adding or uneven dispersing may happen is solved, and accordingly eating is convenient and flexible. Compared with traditional solid salt production, during a production process of the liquid salt, a large amount of equipment needed for salt drying can be reduced, energy loss is lowered, and waste water discharging is lowered.

Dual-mode display device and method for projector

The invention discloses a dual-mode display device and method for a projector. The device comprises a rotatable fluorescent wheel, a first drive device, a color wheel and a second drive device. The fluorescent wheel is provided with a plurality of fluorescence color sections. The color wheel is provided with a light filter in multiple colors. The second drive device is a bidirectional drive mechanism driving the color wheel to rotate clockwise and counterclockwise. The device further comprises a starting point recording device. When the color wheel rotates counterclockwise to enable the projector to present a high-brightness mode, the color wheel rotates clockwise to enable the projector to present a bright mode; when the color wheel rotates clockwise to enable the projector to present the high-brightness mode, the color wheel rotates counterclockwise to enable the projector to present the bright mode. According to the dual-mode display device and method, clockwise rotation and counterclockwise rotation of the color wheel are utilized, so two architectures of the high-brightness mode and the bright mode can be produced on the same projector at the same time; the situation that the cost is increased due to the requirement for different color wheels will not happen; moreover, people do not need to worry about the fact that sometimes a high-brightness projector is needed while sometimes a projector with a bright color function is needed, and life convenience is added.
