A video camera comprises a camera body, a view finder part provided on one side surface of the camera body, a battery receiving part located on the one side surface of the camera body, and a battery which is detachably attached to the battery receiving part to function as a grip of the video camera.

A composite video signal is processed for superimposing characters on an image represented by the video signal, where a memory (33) and a character generator (31) used for superimposing the characters at an appropriate position are both controlled by a control unit having an odd-field detector (38), a shift pulse generator (44), a rewrite pulse generator (45) and a window pulse generator (54). The odd-field detector (38) produces an odd-field pulse each time a coming odd field is detected, and the number of the odd-field pulses is counted so as to be compared with the number of H sync pulses of the composite video signal. The number of H sync pulses fed to the character generator (31) is reduced by the number of detected odd-field pulses thereby smoothly naturally moving or scrolling displayed characters vertically starting from an odd field. A given number of character lines are displayed simultaneously with remaining lines being concealed by an electronic window (a) formed in response to the window pulse generator (54), and character data is rewritten, by the rewrite pulse generator (45) responsive to the shift pulse generator (44), such that data of character lines pushed out of the window (a) is erased and data of a new line is added.

A capstan servo system is used in a recording and/or reproducing apparatus which is capable of recording/reproducing either video signals of the NTSC system having a frame frequency of 30 Hz or video signals of the CCIR system having a frame frequency of 25 Hz. The capstan servo system detects the rotation of a capstan for driving a tape and produces an output frequency which is divided. A reference signal has a frequency corresponding to the frame frequency of the system of the video signal to be recorded on and/or reproduced from the tape. There is a phase comparison between the frequency divided signal and the reference signal. The frequency of the output signal of the detector is added to an error signal output of the phase comparison circuit. The resulting sum signal is used to control the rotation of the motor for driving the capstan. The detection circuit produces an output signal having a frequency of 150.multidot.M Hz (where M is a positive integer). The frequency division is capable of dividing the frequency of the output signal of the detection circuit with a selected frequency division ratio of 1/5M or 1/6M.
