    • A color image processing apparatus comprises: a circuit to provide a color image signal consisting of a luminance signal and two color difference signals; a converter to convert the two color difference signals into the hue signal and saturation signal; a compressing circuit to independently compress the dynamic ranges of one of or both of the luminance signal and the saturation signal and to output; a memory to store the hue signal and the output of the compressing circuit; and a color printer to reproduce the color image on the basis of the hue signal, saturation signal, and luminance signal stored in the memory. The compressing circuit performs the compression on the basis of a frequency distribution of the input signal levels. With this apparatus, the color balance can be automatically adjusted by use of correction ROMs of a small memory capacity.

    • In order to attain a high-speed thin-out reading operation and to obtain high image quality in an image pickup apparatus, a color filter array of this invention is applied to an interline CCD (image pickup element) in which a vertical CCD is driven in eight phases). The high-speed thin-out reading operation is performed as follows. That is, photoelectrically converted carriers for two horizontal lines are transferred to the vertical CCD every third lines (e.g., C in the first line and M in the second line, C in the fifth line and G in the sixth line, . . . are transferred to the vertical CCD), and residual photoelectrically converted carriers (the Y carrier in the third line, the G carrier in the fourth line, the Y carrier in the seventh line, and the M carrier in the eighth line) are discharged by a substrate discharge operation. Thereafter, the photoelectrically converted carriers in the vertical CCD are sequentially transferred in the vertical CCD, and are output via a horizontal CCD and an output amplifier. Chrominance signal carriers on the 1/2PH axis generated by the color filter array of this invention can be removed by an optical LPF, thus obtaining high image quality.
    • 为了实现高速薄化读取操作并且在图像拾取装置中获得高图像质量,本发明的滤色器阵列应用于其中驱动垂直CCD的行间CCD(摄像元件) 八个阶段)。 高速薄化读取操作如下进行。 也就是说,用于两条水平线的光电转换载体每三行传输到垂直CCD(例如,第一行中的C和第二行中的M,第五行中的C和第六行中的G ... 转移到垂直CCD),剩余的光电转换载体(第三行中的Y载波,第四行中的G载波,第七行中的Y载波,以及第八行中的M载波)通过 基板放电操作。 此后,垂直CCD中的光电转换载体在垂直CCD中依次传送,并通过水平CCD和输出放大器输出。 由本发明的滤色器阵列产生的1 / 2PH轴上的色度信号载体可以通过光学LPF去除,从而获得高图像质量。
