摘要： A method is described for applying an image enhancement algorithm to input digital images represented in different input color spaces including identifying the input color space of an input digital image, and applying a color space transformation to the input digital image represented in the input color space to form a corresponding input digital image in a reference color space. The method also includes adjusting one or more algorithm parameters of the image enhancement algorithm in response to the identified input color space, and applying the image enhancement algorithm with the one or more adjusted algorithm parameters to the corresponding input digital image in the reference color space to produce an enhanced digital image in the reference color space.

摘要： A lens in a waveguide of an integrated optical circuit is achromatized (corrected for chromatic dispersion which varies the focal length of the lens with wavelength) by forming the lens as a hybrid mode-index/diffractive doublet. The chromatic dispersion of the diffractive element cancels the dispersion of the refractive element (the mode-index lens) such that the derivative of the focal length goes to zero at the design wavelength, and significantly reduces chromatic dispersion over a substantial wavelength range. For example, a 10 mm focal length, F/5 hybrid mode-index/diffractive lens may be provided with a useable wavelength range of approximately 80 mm for typical waveguide materials.
摘要翻译： 通过将透镜形成为混合模式折射/衍射双峰，集成光电路的波导中的透镜被消色差（校正为通过波长改变透镜的焦距的色散）。 衍射元件的色散抵消折射元件（模式折射率透镜）的色散，使得焦距的导数在设计波长处变为零，并且在相当大的波长范围内显着地减小色散。 例如，对于典型的波导材料，可以为10mm焦距F / 5混合模式折射率/衍射透镜提供大约80mm的可用波长范围。

摘要： A method for determining colorant control values for a color imaging device having four or more colorants is disclosed. The method includes defining a color mapping for a set of paths through a three-channel color space, defining a color mapping function for the three-channel color space relating the three-channel color space values to colorant control values for the four or more colorants of the color imaging device by interpolating between the color mapping defined for the set of paths, forming a forward three-channel color model relating the three-channel color space values to device-independent color values, inverting the forward three-channel color model to determine an inverse three-channel color model relating the device-independent color values to the three-channel color space values, and combining the inverse three-channel color model and the color mapping function to determine an inverse device color model.
