Abstract: 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.

Abstract: 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.
