摘要： The image processing apparatus includes a first generation unit that generates a color signal component for a luminance signal, a second generation unit that generates a color signal component for a chrominance signal, a first tone conversion unit that performs a first tone conversion, a second tone conversion unit that performs a second tone conversion, a third generation unit that generates a color signal component used in common, and a third tone conversion unit that performs a third tone conversion on a signal after being processed by the third generation unit. The first and second tone conversion units perform tone conversion using a conversion amount smaller than a conversion amount that matches the target curve, and the third tone conversion unit performs tone conversion using a conversion amount corresponding to a difference from the target curve.

摘要： An image processing system performs intensity mapping in a manner that avoids color shifts and conserves processing resources while adapting image data for a target display device. The image processing system may convert input image data to a target color space in which brightness components are orthogonal to other color components. When intensity mapping is performed on image data, the intensity mapping operations do not induce the color shifts that were created in these other proposals. Resource conservation may be achieved by altering operation of perceptual quantization processes as used in other intensity mapping systems. Where prior proposals performed perceptual quantization on all color components of the image data being processed, the disclosed embodiments perform perceptual quantization on only a brightness color component of image data. Thus, these embodiments avoid resource expenditures that otherwise would be spent on perceptual quantization of two other color components.

摘要： Based on a histogram of saturation of an input video, a saturation conversion function is determined, and, referring to the determined saturation conversion function, the saturation of each pixel of the input video is converted. Alternatively, a saturation conversion coefficient determination function is generated from the histogram, a saturation conversion coefficient is determined from the saturation conversion coefficient determination function and the saturation, and color differences are multiplied by the determined saturation conversion coefficient. Regardless of what saturation distribution the input video has, the saturation can be properly enhanced, and at the same time a high gradation expression can be obtained.

摘要： A signal converting method includes: receiving RGB signals; enhancing color of a red component, a green component, and a blue component of the RGB signals to convert the RGB signals into RGBY signals; and outputting the converted RGBY signals.
