摘要： A tincture adjustment value used to adjust a monochrome signal to a tincture desired by a user is set, and a tincture conversion table and chromaticity line table are generated based on that tincture adjustment value and the profile of an image output apparatus. Using the generated tables, a lightness signal L* corresponding to an input monochrome signal is converted into a distance signal l on a chromaticity line, and the distance signal l is converted into a chromaticity signal (a*, b*). The lightness signal L* and chromaticity signal (a*, b*) are converted into a color signal of the image output apparatus.

摘要： In some embodiments, color and contrast enhancement video processing may be done in one shot instead of adjusting one of color and contrast enhancement, then the other, and then going back to the first one to readjust because of the second adjustment. In some embodiments, global lightness adjustment, local contrast enhancement, and saturation enhancement may be done at the same time and in parallel. Lightness adjustment improves visibility of details for generally dark or generally light images without changing intended lighting conditions in the original shot, and is used to enhance the range of color/saturation enhancement. Local contrast enhancement done in parallel improves visual definition of objects and textures and thus local contrast and perceived sharpness.
摘要翻译：在一些实施例中，可以一次进行颜色和对比度增强视频处理，而不是调整颜色和对比度增强之一，然后调整另一个，然后返回到第一个以由于第二调整而重新调整。在一些实施例中，可以同时并行地进行全局亮度调整，局部对比度增强和饱和度增强。亮度调整提高了一般黑暗或一般较轻的图像的细节的可视性，而不改变原始照片中的预期照明条件，并且用于增强色彩/饱和度增强的范围。并行的局部对比度增强可以提高对象和纹理的视觉定义，从而提高局部对比度和感知锐度。

摘要： An apparatus and method for adjusting hue in an image processing device are provided. The method includes: setting a rotation angle of hue of each of regions of an image divided into a predetermined number about a central point; calculating coordinates of hue values Cr and Cb of an input pixel to determine in which of the regions the pixel is located; calculating an angle of the pixel in the determined region; calculating a movement angle using rotation angles set for the determined region and an adjacent region, and determining whether interpolation is to be performed to the angle of the pixel based on a difference between the movement angle and the angle of the pixel; and if it is determined that the interpolation is to be performed, calculating an interpolation angle using the movement angle and the angle of the pixel, and moving the pixel by the interpolation angle.

摘要： What is disclosed is a novel system and method for adjusting the gray balance of a multifunction color marking device in order to change the device's neutral behavior to a desired level of acceptability. The gray balance aim curve is specified by: L*, L*(aim), a*(aim) and b*(aim), where L*(aim)=f1(L*), a*(aim)=f2(L*), and b*(aim)=f3(L*). After receiving the user-modified gray balance aim curve, the target color device constructs a 3-D N×N×N L*a*b* to L*a*b* pre-LUT to reflect the neutral aim change by transforming a neutral axis input of L*, a*=0 and b*=0 to L*(aim), a*(aim) and b*(aim). Colors further away from the neutral axis are shifted by a lesser amount. The pre-LUT is then concatenated with the current color LUT to produce an updated color LUT which is applied to the device to achieve the desired neutral behavior. The gray balance aim curve can also be based upon a pre-determined user preference.

摘要： There is provided a white balance control method. A color space coordinate expressing a color signal of each divided block is transformed into a white balance determination space coordinate. A light source estimation area and a high-saturation determination area are set in a white balance determination space to which the transformed white balance determination space coordinate belongs. A kind of the light source is estimated based on a white balance determination space coordinate distribution in the light source estimation area. A kind of the light source is determined based on the estimated kind of the light source and a white balance determination space coordinate distribution in the high-saturation determination area. White balance control information is calculated based on the determined kind of the light source. White balance control with respect to an image signal is carried out based on the calculated white balance control information.
