    摘要： A VCR integrally provided with a camera (camcorder) stops power supply at a non-recording mode for reducing power consumption. The camcorder is arranged to have power control units and a switch for controlling the start or the end of the recording operation and the power-on or power-off of at least one or more of a camera section, a VCR section and a display section, a time measuring unit, and a control unit for starting the recording unit a predetermined time later than when the camera section starts to pick up an image sequence and the image sequence appears on an electronic viewfinder or the like. Further, the camcorder includes units for moving a zoom lens to a Wide-terminal when powered off, when powered on or a predetermined time later than when powered off. Moreover, there are provided units for overlapping text information with the image sequence appearing on the electronic viewfinder. These units display a time left until the recording start. The camcorder further provides units for varying a predetermined time left until the recording start and units for selecting a moving timing on which the zoom lens is moved to the Wide-terminal so that the user may freely set the predetermined time and the moving timing.

    摘要： A tracking apparatus for a helical scan magnetic recording/reproducing system includes a rotation speed controller for controlling the rotation speed of a capstan motor which transports a magnetic tape, a speed deviation generator for applying a deviation to the rotation speed, an envelope level detector for detecting the envelope level of a reproduced signal, a memory for storing the value of detection by the envelope level detector, and an envelope level comparator for comparing envelope levels before and after the deviation is applied to the rotation speed, whereby the rotation of the capstan motor is controlled so that the envelope level becomes a value in the vicinity of a maximum value. The tracking apparatus further includes a steady speed deviation detector for detecting a steady speed deviation between a recording apparatus and a reproducing apparatus, and a steady speed deviation corrector for correcting the detected speed deviation.
