Video apparatus with image forming means responsive to touch sensitive display |
摘要 |
A title can be easily inserted in a video image while taking a video picture. A touch panel is provided on a display screen of an LCD panel. An analog switch section supplies coordinate values Vx, Vy representative of a position of a touch panel pressed by a pen to a microcomputer. The microcomputer adjusts and processes the coordinate values Vx, Vy such that they match a picture angle of the LCD panel and a dot appears at the position pressed by the pen and writes the dot data in the corresponding address of an SRAM. A RAM controller reads the dot data from the SRAM in synchronism with a pick-up video signal under control of the microcomputer and controls selection of switches in response to the dot data. A white level signal corresponding to the dot data is superimposed on the pick-up video signal to generate a display video signal and a recording video signal.
