    • An iris controls the amount of light transmitted through television camera lens to an integrated semiconductor matrix of light responsive elements. A characteristic of the matrix is that photo-charges may overflow the light responsive elements if the light falling on the matrix becomes too bright. The normal iris control responds to a loss of picture contrast caused by the overflow of charges and attempts to increase contrast by increasing the amount of light passing through the lens. The invention compares the output from the light responsive elements with a reference signal representing black areas in the picture. When the comparison exceeds a given difference, a special iris control overrides the normal iris control in order to reduce the amount of light passing through the lens. The reference signal may be taken from one or more of the light responsive elements which are shielded from light passing through the lens. Or, the reference signal may be taken during periods between picture frames when the video signal does not record any light.
    • 光阑控制通过电视摄像机镜头传输到光响应元件的集成半导体矩阵的光量。 矩阵的特征在于,如果落在矩阵上的光变得太亮,则光电荷可能溢出光响应元件。 正常的光圈控制响应于电荷溢出引起的图像对比度的损失,并尝试通过增加透过透镜的光量来增加对比度。 本发明将来自光响应元件的输出与表示图像中的黑色区域的参考信号进行比较。 当比较超过给定的差异时,特殊的虹膜控制将覆盖正常的光圈控制,以减少通过透镜的光量。 参考信号可以取自被透过透镜的光屏蔽的一个或多个光响应元件。 或者,当视频信号不记录任何光时,可以在图片帧之间的周期期间拍摄参考信号。

    • A solid state, color image pickup apparatus separates incident light into three light beams, which diverge in three directions, to form three separate images. Two solid state image pickup devices correspond to a first and a second of the three images formed by the separated light beams. The two object images are a luminance light or a green light image, each having a first spectro-characteristic requiring a high visible resolution. The two solid state image pickup devices receiving the first and second images are displaced away from each other, by a distance in a row direction corresponding to 1/2 of the distance between adjacent picture elements, as viewed in the row direction. A color filter is located at the position of a third object image. The color filter includes cyclically recurring optical filters having a second spectro-characteristic (a blue light characteristic). Neither of these characteristics requires a high visible resolution. Another solid state image pickup device is illuminated with the object image, transmitted through the color filter in order to produce two separate images, depending upon the positions of the color filters.

    • Picture elements or light-sensitive elements of a solid-state area image sensor have associated color filter elements with three spectral sensitivity characteristics. The human eye requires a first of these colors to have a spectral sensitivity characteristic for producing a high level of visual resolution such as, for example, a green light of a luminance characteristic. The human eye does not require the second and third colors to have such a high resolution of a spectral sensitivity characteristic, such as, for example, a red or blue light, respectively. The green light-sensitive picture elements are arrayed at alternate picture element positions in every horizontal row and at alternate scanning line positions in every vertical column, in order to form a checkerboard pattern. The remaining picture elements are arrayed so that the interspaces between the green light-sensitive picture elements are alternately occupied in the successive scanning lines by the red and blue light sensitive picture elements. Narrow-band signals are provided by the light-sensitive elements for each color and a wide band signal is provided for the color requiring a high resolution. From these various signals, a narrow band signal is synthesized to improve the resolution of the entire picture.
