Title:
VIDEO CAMERA DEVICE
Document Type and Number:
Japanese Patent JPH01165291
Kind Code:
A
Abstract:
PURPOSE:To produce an original video by a user himself by adding additional color difference signals to color difference signals at an optional rate so as to obtain composite color difference signals. CONSTITUTION:When pressure is applied to a pressure-sensitive conductive rubber sheet 1, the X- and Y-axis components of the pressure applying point are respectively detected by an X- and Y-signal detectors 2 and 3 as voltages. Then the X- and Y-signal voltages 21 and 31 detected as voltages are A/D converted and the address position is stored in a memory 6. On the other hand, the image pickup element output signal obtained by an image pickup element 8 is processed at a signal processing circuit 9 and becomes luminance signals 91, R-Y signals 92, and B-Y signals 93. Additional signals 61 are generated during the video signal period corresponding to the address position read-out from the memory 6 and become additional luminance signals 51, additional R-Y signals 52, and additional B-Y signals respectively having optional levels and polarities under the control of a control circuit 5. When the additional color difference signals are added to these color difference signals at optional rates, composite color difference signals are obtained.
