摘要： A CPU 20 assumes a virtual color monitor in which actual chromaticity coordinates of colors expressed by fluorescent materials are replaced by virtual chromaticity coordinates having the same hues as those of the actual chromaticity coordinates but higher saturations than those of the actual chromaticity coordinates. The CPU 20 converts colorimetric values X, Y, and Z into luminance-linear values r′, g′, and b′ for red, green, and blue, based on a relationship of color conversion for the virtual color monitor at step S23. The CPU 20 then sets any one of the values r′, g′, and b′ to L at step S24 and compares the value L with i at step S26, where i is the &ggr;-th power of j and greater than 0. In case that the value L is less than i, the CPU 20 calculates a value c based on the remaining values other than the value L among the values r′, g′, and b′ at step S27. When −ck≦L

摘要翻译： CPU20采用虚拟彩色监视器，其中由荧光材料表示的颜色的实际色度坐标被替换为具有与实际色度坐标相同的色调的虚拟色度坐标，而是比实际色度坐标的色饱和度更高的饱和度。 基于在步骤S23中的虚拟彩色监视器的颜色转换的关系，CPU 20将色度值X，Y和Z转换为用于红色，绿色和蓝色的亮度线性值r'，g'和b'。 然后，在步骤S24，CPU 20将值r'，g'和b'中的任何一个设置为L，并在步骤S26将值L与i进行比较，其中i是j的γ次方，大于0。 在值L小于i的情况下，CPU 20在步骤S27中基于值r'，g'和b'之间的除了值L之外的剩余值计算值c。 当-ck <= L <0时，在步骤S28，根据线性函数L进行值L的转换，其中L截距随着值c的变化而变化。 另一方面，在值L不小于i的情况下，CPU20在步骤S30中根据L的1 /γ次幂的函数执行值L的变换。 在接下来的步骤S32中，CPU20将如此获得的值V设置为与在步骤S24中设定的值r'，g'和b'之一相对应的显示信号R，G和B之一。 该颜色转换处理有效地防止了在可再现的颜色范围之外的期望颜色的区域中的异常色调或色调变化。

摘要： To measure the optical power level of light from an object to be measured, a bias section applies to a photo-detecting section such a reverse bias voltage as makes the current multiplication factor M almost zero to prevent the output current from flowing, and then applies such a reverse bias voltage as makes the M one or more to allow the output current to flow. A processing section determines an offset level from the output of a direct-current amplifying section during an offset data acquisition period that the M is almost zero. The time T0 from when the bias section applies to the photo-detecting section such a reverse bias voltage as makes the M one or more to when the reverse bias voltage is applied to make the M almost zero is determined to be a measurement state. The processing section measures the optical power with a clock faster than time T0. The processing section subtracts the offset level from the measured optical power level to compensate for the offset, thereby determining the correct optical power level of the measured object. This makes it possible to automatically perform offset compensation without shading light before measurement and realize highly accurate measurement.

Then differences between the preliminary sharp signals S.sub.0, S.sub.34, S.sub.90 and S.sub.135 and an unsharp signal U are obtained and the difference which has the maximum absolute value is selected as a detailed original signal. A detailed signal is generated by multiplying the detailed original signal by a predetermined coefficient K.

摘要： Detail enhancement is achieved by producing an enhanced image signal (ES) on the basis of a sharp signal (S), a middle signal (M) and an unsharp signal (U). The sharp signal represents density of a pixel, the middle signal represents weighted mean density of a first area larger than a pixel, and the unsharp signal represents weighted mean density of a second area larger than the first area. Three differential signals (S-M, S-U, M-U) are obtained and multiplied by respective coefficients to become three enhancements signals. The enhanced image signal is obtained by adding the sharp signal and at least one of the three enhancement signals so that the detail enhancement is achieved at a middle range of spatial frequency.

摘要： A linear interpolating method and apparatus for signals in a memory wherein first signals are converted into second signals by addressing in at least four-dimensional fashion, for use in a color picture processing machine such as a color scanner, a color facsimile, a color T.V. monitor, and other signal processing machine converting coordinates of signals with at least four variables, are disclosed. The second signals corresponding to certain stepped values of the first signals are read out of the memory, and then the values of the read signals are interpolated at an interpolation point positioned therebetween. At least four-dimensional interpolation unit space is divided into at least four-dimensional dissection spaces, and then it is discriminated which of the dissection spaces includes the interpolation point. Then, the interpolated value at the interpolation point is obtained as a weighted sum of the values at the vertices of the discriminated dissection space.

摘要： A method of color correction of the particular application to a color scanner or a color facsimile for producing color separation images by photoelectrically scanning a color original. Usually, color separation signals obtained from the scanning operation are used as addressing signals for reading out correction signals or already-corrected recording signals memorized in a memory. In this case, according to this method, there is provided before the memory a premasking circuit which is capable of converting the functions of the color separation signals so as to convert co-ordinate systems of the color separation signals and the memorized signals. The conversion of the co-ordinate systems facilitates a considerable reduction of the memory's capacity and, at the same time, achieves more efficient use of the memory.

摘要： A method of color correction of the particular application to a color scanner having a color correction circuit, an analog-digital converter and a memory. Color separation signals obtained by scanning a color original are first compressed to the color ranges reproducible by printing inks by the color correction circuit and then converted at the analog-digital converter to digital signals, which are to be utilized as addressing signals. Memorized in the memory are only correction signals whose absolute values are relatively small so as to effect a considerable reduction of a memory capacity of the memory. The correction signals are read out by the digital signals and added thereto, whereby suitably-corrected signals for recording color separation images can be obtained.
