    • A sensor 11 for a video camera includes a color filter array 12 of color filter elements covering a like array 14 of image sensing elements. Two fields of a video frame are provided by interlaced transfer of image signals from the sensor 11. The color filter array 12 is configured in relation to the sensor array 14 such that at least 75% of the image sensing elements are luminance-sensing (e.g., green) elements and the rest are chrominance-sensing (e.g., red and blue) elements. Furthermore, the chrominance-sensing elements of the same type (red or blue) are separated in a horizontal direction by at least three luminance-sensing (green) elements. The horizontal sampling frequency of the chrominance-sensing elements is increased by arranging horizontal lines containing the chrominance-sensing elements of the same type in staggered line pairs with the chrominance-sensing elements of one line appearing in different columns of the sensor in relation to chrominance sensing elements of the other line.
    • 用于摄像机的传感器11包括覆盖图像感测元件的类似阵列14的滤色器元件的滤色器阵列12。 通过从传感器11的图像信号的隔行传送来提供视频帧的两个场。滤色器阵列12相对于传感器阵列14配置,使得至少75%的图像感测元件是亮度感测(例如, ,绿色)元素,其余的是色度感测(例如,红色和蓝色)元素。 此外,相同类型(红色或蓝色)的色度感测元件在水平方向上分开至少三个亮度感测(绿色)元件。 色度感测元件的水平采样频率通过在交错线对中排列包含相同类型的色度感测元件的水平线,其中一条线的色度感测元件出现在传感器的不同列中,与色度相关 感测另一条线的元件。

    • Electronic Imaging Apparatus is partitioned into separable modular units including an image pickup unit (4a) attachable to an image recording unit (2). The pickup unit (4a) is selected from a plurality of pickup units (4a, 4b), each producing image signals from an image sensor (6, 70, 71) uniquely devoted to the acquisition of a particular type of image (e.g., high resolution vs. low resolution, color vs. monochrome, NTSC motion vs. PAL motion). By providing an identifying signal in connection with the pickup unit, the characteristics of the sensor (6) are specified to the recording unit. More specifically, the recording unit includes a buffer (36) for storing the image signals, a processor (40) for controlling the operation of the recording unit, including the buffer, and interface circuitry (10, 32) for responding to the identifying signal and enabling operation of the processor (40) according to the characteristics of the attached image pickup unit (4a).
    • 电子成像装置被分割为可分离的模块单元,包括可附接到图像记录单元(2)的图像拾取单元(4a)。 拾取单元(4a)从多个拾取单元(4a,4b)中选择,每个拾取单元(4a,4b)产生来自图像传感器(6,70,71)的图像信号,该图像信号专门用于获取特定类型的图像(例如,高 分辨率与低分辨率,彩色与单色,NTSC运动与PAL运动)。 通过提供与拾取单元相关的识别信号,传感器(6)的特性被指定给记录单元。 更具体地,记录单元包括用于存储图像信号的缓冲器(36),用于控制包括缓冲器的记录单元的操作的处理器(40)和用于响应识别信号的接口电路(10,32) 以及根据附加的图像拾取单元(4a)的特性使处理器(40)能够运行。
