摘要： In some examples, a system detects a highlighted area in an image content. The system applies a color adjustment process in the highlighted area. The color adjustment process is not applied in areas of the image content outside the highlighted area, and the color adjustment process includes an operation of adjusting a color of the highlighted area. The adjusting of the colors of the highlighted area includes adjusting a color value of a specified color space.

摘要： In some examples, a computing device includes a first display device coupled to a second display device by hinges. After determining that the computing device has been moved from a first orientation to a second orientation, the computing device may receive ambient light data from ambient light sensors associated with the first and second display device, temperature data from temperature sensors associated with the first and second display device, and color data from color sensors associated with the first and second display device. After determining that power is being received from an external power source or that the user prefers the display devices may be color matched, the computing device may perform one or more color adjustments based on the ambient light data, the temperature data, and the color data, thereby reducing a difference in a perceived color between the first display device and the second display device.

摘要： Recording data for recording an achromatic color image having a high lightness is generated as follows. A first color material and a second color material which has a hue complementary to that of the first color material are used to record the image. Recording data is generated such that a recording amount of the first color material and a recording amount of the second color material are larger than a recording amount of another color material, and such that a pixel where it is determined that the first color material is to be recorded and a pixel where it is determined that the second color material is to be recorded are at positions different from each other.

摘要： One or more apparatus and method for compressing xvYCC or sRGB color to a narrower color gamut. Embodiments may be utilized in processing images/video image sequences provided in a wide gamut color space for display in standard RGB color space. In further embodiments, an sRGB or xvYCC compliant input is compressed to a gamut narrower than sRGB. Embodiments where a narrow output color gamut lacks a fully-defined 3D color space, semi-fixed-hue gamut compression may be performed by adjusting parameters provided to a fixed-hue compression module capable of mapping 3D color space representations between well-defined gamuts.

摘要： An image forming apparatus includes a table generating unit. The table generating unit, in a Voronoi diagram, obtains empty circles as circles centered at Voronoi seeds of ends of Voronoi sides that intersect with a straight line passing through a largest saturation color and a smallest-saturation and specific-lightness color and passes through generatrices. After the table generating unit sets one of the generatrices shared by the two adjacent empty circles whose radius ratio is outside a specific range as a target point, and causes the radius ratio of the two empty circles to be within the specific range by changing at least one radius of the two empty circles, the table generating unit generates the conversion table that sets a color that corresponds to an intersection point corresponding to the target point among the intersection points of the two empty circles, as the definition colors.
