An image conversion system for altering an image to adjust the overall brightness of the image when displayed is provided. The image conversion system includes a luminance transformer and a color adjuster. To adjust the overall brightness of the image, the luminance transformer reverses the luminance of each original color in the image. The new luminance of each transformed color is then compared to the desired luminance for that color. When the transformed colors do not have the desired luminance, the color adjuster modifies the hues of transformed color to achieve the desired luminance. Specifically, the color adjuster modifies the transformed color using a weighted average to achieve the desired luminance while maintaining the hues of the original color to the extent possible. By substituting each original color with a transformed color that is adjusted as needed to reach the desired luminance, the overall brightness of the image is adjusted.

An improved method is provided for applying an antireflective high contrast coating to a lens, as well as a lens system made with said method. By coating the lenses with a mixture of an oxide and fluoride, the transmission of undesirable visible light wavelengths is reduced, as is the reflection of undesirable light. This combination not only increases perceived sharpness and detail associated with viewing objects through the lenses, but also reduces undesirable reflected glare. Utilization of increased vacuum during the coating process reduces problems of humidity associated with plastic lenses. The combination of oxide and fluoride is controlled to reduce colored tint or hue in the resulting lenses. By imparting little to no color hue to the lenses, the lenses virtually eliminate any undesired color shift associated with prior art lenses.

The invention provides a method for detecting skin colors and the pigmentation situation of skin. The effect of conducting color division on a skin image in a Lab color space is superior to a skin color dividing effect in an RGB color space. Especially when skin colors have similar brightness values and different tone values, division is very difficult in the RGB color space, but a good division effect is achieved in the Lab color space. In addition, more edge noise can be removed after the skin image is subjected to median filtering treatment. Furthermore, the exposure gain and white balance parameters of an image acquisition device to be calibrated are adjusted in the mode of establishing a standard device till the differences between testing component values and standard threshold values are smaller than the same error value. The lighting influence is effectively overcome, skin colors in the skin image is accurately divided, and the pigmentation situation of the skin is analyzed.

Since each pillar emits light at a different wavelength according to its diameter and strain state, the overall emission spectral characteristics of the device is a combination of individual spectrum, giving rise to broadband emission. The spectral shape can be tailored for different shades of white emission, by controlling the distribution of the different diameter nano-pillars. The nano-pillars are patterned by nanosphere lithography.

A stable, unicolor intermediate density region in a four-color system is defined by mixing dark and light color recording materials in a six-color system. For this reason, a calibration for the four-color system cannot correct density variations, and a pseudo-contour due to discontinuity of tones is produced in a transition region from the light color recording materials to dark color recording materials included in the intermediate density region, thus considerably deteriorating image quality. The tone characteristics of respective colors are obtained from a patch pattern of respective color recording materials, and a tone correction table used to correct the tones of the respective colors is created on the basis of the tone characteristics of the respective colors. The tone characteristics of primary colors calculated from the tone characteristics of the respective colors with reference to a basic color density characteristic table indicating the density characteristics when the dark and light color recording materials are mixed. A basic color density correction table used to correct the tone characteristics of the primary colors is created with reference to the basic color density characteristic table and the density correction table.

The present invention is directed to a process for predicting the tint strength of a pigmented coating composition, such as automotive OEM or refinish paint, on a real time basis while it is being made. The tint strength of a coating resulting from a layer, obtained by adding a reference binder to the coating composition, is measured. The process is repeated by subjecting the coating compositions to successive grinding intervals. The tint strength vs. reflectance is plotted on a graph and then by using a curve fitting equation, a tint strength prediction curve is obtained. By measuring the reflectance of a wet layer of a target coating composition, the tint strength of that target coating composition can then be predicted by using the tint strength prediction curve. The process is most useful during the manufacture of coating compositions, such as automotive OEM and refinishes paints.
