<p>PROBLEM TO BE SOLVED: To provide a digital still camera having a duplex exposure function such as a general optical camera which can compose video data that is taken twice into one digital video and which can be made into the video that is doubly exposed. SOLUTION: A video image pickup means 10 converging inputted light and converting it into an electric signal so as to output it, an analog-digital conversion part 20 converting the analog signal inputted from the video image pickup means 10 into the digital signal so as to output it and a video composing means 30 storing the digital signal inputted from the analog/digital conversion part 20 in accordance with the inputted control signal in a field unit and synthesizing the signals in the field unit so as to output it are provided. Furthermore, a control part 40 controlling the video synthesis means 30, a digital/analog conversion part 50 converting the signal inputted form the video composing means 30, a recording device 60 storing the signal inputted from the video synthesis means 30 in accordance with the control signal and a computer interface 70 transmitting the signal inputted from the video composing means 30 to the computer in accordance with the control signal inputted from the control part 40 are contained.</p> |
