    • An area separating apparatus for judging whether or not each object pixel belongs to a photograph image area in an image. The apparatus includes: an average value calculating circuit for calculating an average value of image data of pixels in an image block containing the object pixel; a photograph image area judgment threshold generating circuit for generating a photograph image area judgment threshold in accordance with the average value; a density difference summing circuit for determining differences in image data between respective adjacent pairs of pixels in the image block and calculating a sum of the image data differences for all the pixels in the image block; and a judgment circuit which judges that the object pixel belongs to the photograph image area if the sum of the image data differences is smaller than the photograph image area judgment threshold, and judges that the object pixel does not belong to the photograph image area if the sum of the image data differences is not smaller than the photograph image area judgment threshold.
    • 用于判断每个对象像素是否属于图像中的照片图像区域的区域分离装置。 该装置包括:平均值计算电路,用于计算包含对象像素的图像块中的像素的图像数据的平均值; 照片图像区域判断阈值生成电路,用于根据平均值生成照片图像区域判定阈值; 密度差求和电路,用于确定图像块中各个相邻像素对之间的图像数据的差异,并计算图像块中所有像素的图像数据差的和; 以及如果图像数据差的和小于照片图像区域判断阈值则判断对象像素属于照片图像区域的判断电路,并且如果对象像素不属于照片图像区域,则判断对象像素属于照片图像区域 图像数据差的和不小于照片图像区域判断阈值。

    • An optical film has a film a formed of a cyclic olefin resin, and a homeotropically orientated optical anisotropic layer b disposed on the film a. This optical film preferably satisfies the below listed formulae (1) to (3). −600nm≦Rth≦200nm  (1) 0nm≦R≦600nm  (2) NZ≦1  (3) (In formulae (1) to (3), Rth indicates the retardation in the thickness direction of the optical film at a wavelength of 550 nm; R indicates the in-plane retardation of the optical film at a wavelength of 550 nm; and NZ indicates (nx−nz)/(nx−ny)).When the optical film is used in an ISP mode liquid crystal display device, light leakage and color fading (discoloration) during black display are prevented stably for a long term, and a good viewing angle compensation effect is obtained (i.e., high contrast ratio at all angles).
