    • Provided are a method and apparatus for generating a wide color gamut signal in an image capturing device, which can simplify a calculation process and minimize color distortion therein. The apparatus includes a gamma-correction unit gamma-correcting a picked-up image signal by using gamma curve information predetermined according to an output format; an interpolation unit interpolating the gamma-corrected image signal as a linear image signal which is to be expressed on a display; a color gamut conversion unit converting the interpolated image signal into a standard RGB signal by using a color conversion matrix; a color expansion unit expanding the standard RGB signal to a wide color gamut signal by using a gamut conversion matrix; and a signal correction unit correcting the wide color gamut signal by a predetermined correction gain value.
    • 提供了一种用于在图像捕获装置中产生宽色域信号的方法和装置,其可以简化计算过程并使其中的色彩失真最小化。 该装置包括:伽马校正单元,通过使用根据输出格式预先确定的伽马曲线信息对所拾取的图像信号进行伽马校正; 内插单元,将伽马校正图像信号内插为要在显示器上表达的线性图像信号; 色域转换单元,通过使用颜色转换矩阵将内插图像信号转换为标准RGB信号; 色彩扩展单元,通过使用色域转换矩阵将标准RGB信号扩展到宽色域信号; 以及信号校正单元,通过预定的校正增益值来校正宽色域信号。

    • A data transmitting/receiving apparatus and method in which color gamut information is added to a teletext signal in a blanking interval so that a display device can recognize whether a color gamut has been extended, are provided. The apparatus includes a control unit which determines whether an image signal is a wide color gamut signal. A signal processing unit encodes color gamut information of the wide color gamut signal and allocates the color gamut information to a data region of a teletext interval if it is determined that the image signal is the wide color gamut signal. The signal processing unit transmits an image signal including a teletext packet in which the color gamut information is recorded.
    • 一种数据发送/接收装置和方法,其中在消隐间隔中将色域信息添加到文字多重信号,使得显示设备可以识别色域是否已经被扩展。 该装置包括控制单元,其确定图像信号是否是宽色域信号。 如果确定图像信号是宽色域信号,则信号处理单元对宽色域信号的色域信息进行编码,并将色域信息分配给图文电视间隔的数据区域。 信号处理单元发送包括其中记录色域信息的图文电视分组的图像信号。
