摘要： A liquid crystal display device includes a liquid crystal display panel having a pixel defined by at least three sub-pixels including a blue sub-pixel, a backlight which emits, toward the liquid crystal display panel, light that brings a color temperature to a predetermined level when the pixel displays white, and a color tone correction circuit which corrects a color tone of a color displayed by the pixel. When the pixel displays a color containing at least one predetermined color component that is other than a white component and a blue component, the color tone correction circuit performs a correction to set a luminance of the blue sub-pixel lower than an original luminance.

摘要： A method of correcting a preferred color is disclosed. The method includes converting an input image including multi-primary color data of three or more primary colors into an XYZ color space, converting the XYZ color space into data of an LCH color space, expanding a color gamut of the data in the LCH color space to detect a preferred color region of the color gamut expansion data, correcting data of the preferred color region using parameters independent of the input image, inversely converting the corrected data of the preferred color region of the color gamut expansion data into an XYZ color space, dividing the XYZ color space into multi-primary color data of four or more primary colors, and displaying the multi-primary color data on a display device.

摘要： Aspects of the invention provide a color matching profile generating device that, in an apparatus having an input device and an output device, performs a color matching for the input device and the output device and reproduces favorable colors without depending on color characteristics of the devices. The color matching profile generating device can use an input device profile and an output device profile, in addition to a color conversion profile which defines color conversion characteristics in an absolute color space and generates a color matching profile for the input device and the output device. Since the color conversion profile defines the color conversion characteristics in the absolute color space, color conversion can be performed to image data obtained from the input device without depending on characteristics of the input device. Accordingly, by performing a color matching process with the generated color conversion profile, image data can be output with color characteristics determined in the absolute color space, irregardless of characteristics of the output device.
摘要翻译：本发明的方面提供了一种颜色匹配简档生成装置，在具有输入装置和输出装置的装置中，对输入装置和输出装置进行颜色匹配并再现有利的颜色，而不依赖于装置的颜色特性。除了在绝对颜色空间中定义颜色转换特性的颜色转换曲线，并且为输入装置和输出装置生成颜色匹配曲线，颜色匹配轮廓生成装置可以使用输入装置轮廓和输出装置轮廓。由于颜色转换轮廓限定了绝对颜色空间中的颜色转换特性，因此可以进行颜色转换，而不依赖于输入装置的特性来从输入装置获得的图像数据。因此，通过利用所生成的颜色转换曲线进行色彩匹配处理，可以输出具有在绝对色彩空间中确定的颜色特性的图像数据，无论输出装置的特性如何。

摘要： An object of the present invention is to provide an image display technology with which high contrast can be stably obtained. In order to achieve the above object, the present invention changes the gain of a digital luminance signal by feeding back information on maximum and average luminance levels of the luminance signal, adjusts image contrast, and in accordance with the average luminance level detected from the feedback system, controls the illuminance of the backlight applied to a display unit. The control increases the illuminance of the backlight when the detected average luminance level is higher than the upper-limit value of a previously set reference range, and reduces the illuminance when the detected average luminance level is lower than the lower-limit value of the reference range.

摘要： A device performs both 2-tap and 3-tap flicker filtering of non-interlaced lines of computer graphics data to form interlaced lines. The device includes a data packer, a data unpacker, and a filter circuit. The filter circuit combines lines that it receives to form filtered lines. The data packer writes the filtered lines to line buffers while the data unpacker reads the lines stored in the line buffers. The read lines are either sent to the filter circuit for further filtering or are outputted to be displayed as interlaced lines. Both 2-tap and 3-tap flicker filtering can be accomplished by varying the order and/or number of read, write, and filter operations.

摘要： An improved method and apparatus for rendering curved surfaces in a graphics system. The appearance of a curved surface is created by varying color shades across an object. The graphics systems represents each primary color with fewer than eight bits. The present invention maintains smooth transaction between color shades despite using fewer than eight bits to represent color. An eight bit color shade value is truncated, with the most significant bits being saved and used as a color value. The least significant bits that are truncated are used to determine which of the adjacent color values to use to render pixels. Thus, if five bits are saved and used to represent a color, the three least significant truncated bits are used to determine the appropriate mix of the closest five bit shades. The three truncated bits are used to select an entry from a ramp table and a control signal from a look-up table selects a bit from the selected ramp table entry. The selected bit is used to determine which of the closest five bit shades to use for rendering a pixel. The invention may be implemented in software.

摘要： An apparatus and method a method for performing two-pass real time video compression is provided. Tactical decisions such as encoding and quantization values are determined in software, whereas functional execution steps are performed in hardware. By appropriately apportioning the tasks between software and hardware, the benefits of each type of processing are exploited, while minimizing both hardware complexity and data transfer requirements. One key concept that allows the compression unit to operate in real time is that the architecture and pipelining both allow for B frames to be executed out of order. By buffering B frames, two-pass motion estimation techniques can be performed to tailor bit usage to the requirements of the frame, and thereby provide a more appealing output image.
