<p>PURPOSE: To provide a video device which can easily add a title on a screen during photographing. CONSTITUTION: A touch panel 11 is provided on the display surface of an LCD panel 9. An analog switch part 20 sequentially supplies coordinate values Vx and Vy showing the depressed position of the touch panel 11 by a pen 30 to a microcomputer 3. The microcomputer 3 adjusts/works the coordinate values Vx and Vy so that they are adjusted to the picture angle of the LCD panel 9 and a dot appears in the depressed position of the pen 30, forms address data (x, y) of SMF 31 and writes dot data on the corresponding address of SRAM 31. A RAM controller 10 reads dot data from SRAM 31 in synchronisum with an image pickup video signal SVi, controls the switching of change-over switches 7 and 6 based on dot data, overlaps a white level signal Swh with the image pickup video signal SVi in accordance with dot data and obtains a display video signal SVd and a recording video signal SVr under the control of the microcomputer 3.</p> |
