    摘要： In an automatic white balance control apparatus which is less sensitive to a monochromic subject, color difference signals R-Y and B-Y are converted into digital values by A/D converters (20, 21). A quadrant determination circuit (22) determines for each digital color difference value to which quadrant of a two-dimensional coordinate system with an ordinate representing (R-Y) and an abscissa representing (B-Y) it belongs. Digital color difference values within one field are accumulated by accumulation device (28, 29, 30) per each quadrant. With respect to the digital color difference values (R-Y) wig& one field, digital difference values of pairs each one sampling period apart from each other are accumulated per each quadrant. The above two kinds of accumulations are carried out also with respect to the digital color difference values (B-Y) within one field. When the accumulated values of the two color difference values (R-Y) and (B-Y) within the respective quadrants are compared to control gains for R-Y and B-Y by a microprocessor (31), the accumulated value of the color differences in the quadrant, of which accumulated value of the digital difference values is small, is given a small weight.

    摘要： An automatic focus control device capable of obtaining an accurate in-focus state of a subject having less high-frequency components is provided. A luminance signal of the video signal of the subject is first differentiated by a combination of a delay circuit (27) and a difference forming circuit (26). The differentiated luminance signals are accumulated by an accumulator (31), and a clock pulses CL are counted by a counter (32) during the periods when the differentiated luminance signals exceed a predetermined value. The accumulated value is then divided by the clock count at a divider (33) to obain a focus control signal which is fed to a microcomputer (35). The microcomputer causes a lens (11) to move in accordance with this focus control signal so that an optimum in-focus state of the subject is obtained.

    摘要： An optical image transmitted by an image transmitting member of a fiber scope is photoelectrically converted by an imaging device, is passed through a signal processing circuit and is displayed in a predetermined displaying position on a displaying picture surface. The range of the image imaged by the imaging device from the output signal from an imaging unit fitted with an image guide transmitting member on the exit end surface and containing the imaging device is detected, the value of the center position of the range is determined and the displaying position is corrected in response to the value.
