摘要： The color reproduction performance of image input/output devices has been improved greatly and even very slight changes in color ascribable to a color balance correction are recognizable. As a consequence, there are cases where a specific color shift, such as a color shift in the yellow or blue direction, gives a disagreeable sensation when applied with regard to a slight color change in the color of the human skin, which is a memory color. Accordingly, highlight and shadow points are detected based upon the histogram of an image, color information of the highlight and shadow points is revised by adjusting average color difference information based upon a hue angle acquired from average color difference information of image data having luminance levels of the highlight and shadow points, and the image is corrected based upon the revised color information of the highlight and shadow points.

摘要： When printing image data obtained by an input device, the present invention is intended to effectively utilize the color reproduction area of the printer. An image data processing method of the present invention comprises the steps of scale-down shifting a first color space point outside a maximum color reproduction area of an output unit to a second color space point within the maximum color reproduction area of the output unit; computing an amount of shift by which the first color space point is shifted to the second color space point; converting the second color space point to a third color space point within a color reproduction area smaller than the maximum color reproduction area of the output unit; and outputting an image to the output unit using image data obtained by scale-up shifting the third color space point to a fourth color space point within the maximum color reproduction area of the output unit based on the computed shift amount.

摘要： On the basis of a discrimination parameter for discriminating more detailed brightness in an image, the brightness of the image is discriminated, and the optimum degree of correction component is set for the image, thereby performing a more faithful reproduction of the image indicated by image data. Therefore, a highlight point being a brightness value associated with a cumulative frequency of reaching a predetermined value is calculated in a high-brightness area on the basis of a histogram obtained with respect to the number of pixels of a brightness value indicated by the image data, and the image is discriminated in its entire brightness on the basis of the highlight point. On the other hand, a ratio of the cumulative frequency in a predetermined low-brightness area to the number of all the pixels in the histogram is calculated. On the basis of the calculated ratio and the discriminated brightness, a gamma value indicating degree of correction the brightness value to a value of more light image is defined. Accordingly, a suitable correction corresponding to brightness of an image can be performed.
摘要翻译：基于用于区分图像中的更详细的亮度的辨别参数，识别图像的亮度，并且为图像设置最佳的校正分量，从而对由图像数据指示的图像进行更忠实的再现。因此，基于对由图像数据指示的亮度值的像素数获得的直方图，在高亮度区域中计算与达到预定值的累积频率相关联的亮度值的亮点，并且基于高亮点以其整体亮度区分图像。另一方面，计算预定的低亮度区域中的累积频率与直方图中的所有像素数的比率。基于计算出的比率和识别亮度，定义表示亮度值与更多的光图像的值的校正程度的伽马值。因此，可以执行对应于图像的亮度的适当校正。
