    • An imaging apparatus comprises: a color separation optical system for separating an image ray into blue, green, and red image rays, image sensors, having pixels vertically and horizontally arranged, for receiving the image rays and producing blue, red, and green signals wherein at least one of image sensors for blue and red signals has a vertical relative offset against the image sensor for green signal to have a relative interlace relation with the image sensor for blue or red color signal, to produce a screen to be produced, having a higher resolution than these image sensors. A vertical high frequency component is operated from the blue and red signals and is added to the green color signal to produce a second green signal indicative of is a green luminance value at a position corresponding to each pixel of the image sensors for blue and red color signals to increase the vertical resolution of the screen. A fourth image sensor for green and a separation optical system for the fourth image sensor may be provided to increase a horizontal resolution by arranging the fourth image sensor to have a horizontal offset to have a second relative interlace relation with the image sensor for green. The image sensor for blue and red may have a vertical offset to eliminate the necessity of a field memory to operate the vertical high frequency component.
    • 一种成像装置包括:用于将图像光线分离成蓝色,绿色和红色图像光线的颜色分离光学系统,具有垂直和水平排列的像素的图像传感器,用于接收图像光线并产生蓝色,红色和绿色信号,其中 用于蓝色和红色信号的图像传感器中的至少一个具有与用于绿色信号的图像传感器的垂直相对偏移,以与图像传感器具有用于蓝色或红色信号的相对交错关系,以产生要生产的屏幕,具有 比这些图像传感器更高的分辨率。 垂直高频分量由蓝色和红色信号进行操作,并被加到绿色信号上以产生第二绿色信号,表示在与蓝色和红色的图像传感器的每个像素对应的位置处是绿色亮度值 信号增加屏幕的垂直分辨率。 可以提供用于第四图像传感器的用于绿色的第四图像传感器和用于第四图像传感器的分离光学系统,以通过将第四图像传感器布置成具有与图像传感器的绿色的第二相对交错关系的水平偏移来增加水平分辨率。 用于蓝色和红色的图像传感器可以具有垂直偏移,以消除用于操作垂直高频分量的场存储器的必要性。

    • A dark current correction circuit in a two-tube color camera having first and second camera tubes respectively for chrominance signals and luminance signals comprises a circuit for applying to the first camera tube a target voltage in accordance with temperature variation in the image pickup surface thereof, a circuit provided in the picked-up output signal system of the first camera tube and operating to compensate or cancel a dark current component within the picked-up output signal, a circuit for applying to the second camera tube a target voltage in accordance with temperature variation in the image pickup surface thereof, and a circuit for mixing with the picked-up output luminance signal of the second camera tube a horizontal blanking pulse at a level in accordance with the temperature variation in the image pickup surface of that camera tube. The level controlled horizontal blanking pulse, upon being applied to the picked-up output luminance signal, effects correction of a dark current variation component within the luminance signal due to temperature variation in the image pickup surface of the camera tube and for a dark current variation component due to variation of the target voltage.

    • A beach cleaner that is simple in configuration and light in weight and can be manufactured at a low cost. The beach cleaner is easy with regard to maintenance and inspection and can efficiently reclaim various kinds of refuse scattered on a beach. A beach cleaner includes a traveling body with ski members disposed at four corner portions of a frame having a substantially quadrangular shape. The beach cleaner is towed along a surface F of sandy soil by a traction vehicle R. A bar-like scraper is provided at a lower portion of a front portion of the traveling body and extends in a widthwise direction of the traveling body through a scraper supporting member for scraping up refuse on the sandy soil while the traveling body is operating. A refuse reclamation section is provided on the traveling body rearwardly of the bar-like scraper for collecting pieces of refuse scraped up and thrown rearwardly by the bar-like scraper onto a net member.
