Abstract:
PROBLEM TO BE SOLVED: To sufficiently reduce an EMI level without using any EMI countermeasure parts and a housing shielding member which cause cost increase. SOLUTION: A video camera 21 of an analog system is provided with a CCD 22 that photographs an object, a CCD driver 23 that drives the CCD 22, a basic clock oscillator 24 that generates a basic clock, an SSCG 1 that applies spread spectrum processing to the basic clock from the basic clock oscillator 24, an SSG 25 that generates various synchronizing signals based on the basic clock that is spread-spectrum-processed by the SSCG 1, a frequency divider 25 that divides the basic clock by 1/4, and a sample-and-hold circuit 27 that samples and holds an output of the CCD 22.
