摘要： Color compensation is performed in color images for use in an image processing field which is employed for three-dimensional computer graphics and the like by making a luminance value of texture data coincide with an intensity derived by an intensity calculation. Also, lightness compensation is performed for a color image according to a display scene. From measurements of color changes of plural colors in a uniform color space, a color change of arbitrary texture data under a chromatic color light source is represented and compensated. The generated image is very natural because compensation is achieved between a lightness of a texture itself representing a pattern on the surface of an object and an intensity of the surface of the object derived by an intensity calculation when an image is generated.

摘要翻译： 通过使纹理数据的亮度值与通过强度计算导出的强度一致，在用于三维计算机图形学等的图像处理领域中用于彩色图像中进行色彩补偿。 此外，根据显示场景对彩色图像执行亮度补偿。 通过在均匀色彩空间中对多种颜色的颜色变化进行测量，表示并补偿彩色光源下的任意纹理数据的颜色变化。 所产生的图像是非常自然的，因为在产生表面上的表现图案的纹理本身的亮度与当产生图像时通过强度计算导出的对象表面的强度之间实现补偿。

摘要： A 3-dimensional animation generating apparatus includes an image data storing section, a view point information input section, an image supervising section, an image data selecting section, a view point coordinate transforming section, an output image drawing section, a motion addressing section, a shadow area detecting section, and a shadow area supervising section. The image data storing section stores part image data and background image data in association with 3-dimensional coordinates of vertexes included in the image. The image data selecting section searches the image data by a unit of part. The apparatus further comprises a mechanism which, when information related to an observing view point is provided, determines which part image data exists in the visible area, transforms the visible part image data from the observing view point by view point coordinate transformation, and draws the resultant image data in a common drawing area. In addition, the apparatus further searches and supervises the part which can provide a shadow as a shadow area and the position of the light source related with the specific shadow area. When a new view point is selected, the shadow area transformed by view point coordinate transformation is drawn. Thus, the number of data and number of calculations for generating a scene with respect to a selected observing view point are effectively reduced.
