    摘要: In a wireless communication system dealing with a plurality of frequency bands such as 5.2 GHz band and 2.4 GHz band, without a disturbance from another wireless communication system or the like and abnormalities such as stop of a moving picture and disturbance of a picture, a large volume of data can be securely and smoothly transmitted on real time basis. In a frequency band (5.2 GHz band) communicable at higher transmission rates, unused radio channels free of a disturbing wave are detected in steps 101 to 103. In process routine 200, it is detected whether or not received field strengths exceed a threshold value in decreasing order from higher transmission rates on the detected radio channels. A communication is started at a transmission rate of which the received field strength reaches or exceeds the threshold value.

    摘要: A track jump control apparatus for a disc reproducing system having a transport unit for moving a pickup element that reads data recorded on the disc in the radial direction of the disc at a high speed. The system also has a detecting unit for detecting a moving direction of the pickup element unit based on a pick-up signal output from the pickup element while the pickup element moves in the radial direction of the disc, and a protection unit for stopping the pickup element moved by the transport unit when the pickup element is judged to be moving in a different direction from the direction moved by the transport unit. The apparatus has a measuring unit for measuring a pulse duration of the picked-up signal, which is continuously obtained from the pickup element while the pickup element moves in the radial direction of the disc at a high speed. The apparatus also has a control unit for inverting a detected result of the detecting unit when the pulse duration of the picked-up signal is beyond a specific limit based on the measured result of the measuring unit.

    摘要: In an automatic focusing circuit of a video camera, automatic focusing operation is performed by a focus evaluating value formed in response to a video signal obtained by an image sensing circuit (4). A first focusing motor control circuit (15) controls the rotation of a focusing motor (3) so that a focusing lens (1) is once fixed in the position where the focus evaluating value takes the maximum value. A second focusing motor control circuit (17) changes the focusing motor (3), by a predetermined very small amount, to determine the slope of the focus evaluating value, which change is repeated until inversion of the slope, that is, the maximal point is detected. As a result, the position of the focusing lens is corrected at the maximal point of the focus evaluating value. When the correction amount exceeds a predetermined value, first automatic focusing operation by the first focusing motor control circuit (15) is resumed.
