<p><P>PROBLEM TO BE SOLVED: To prevent stereoscopic vision from being hindered by equalizing the vibration-proof performance of a vibration-proof mechanism prepared in each optical system. <P>SOLUTION: During product shipping inspection, control parameters of a PID control means 18a, a gain KL and a phaseϕL of an amplifier L14 are independently set respectively and furthermore control parameters of a PID control means 28a, a gain KR and a phaseϕR of an amplifier R24 are independently set respectively so that an L-side control residual and an R-side control residual are made equal to each other, that is, so that an optical system having better vibration-proof performance is made to agree with another optical system having worse vibration-proof performance. These parameters are stored in a parameter holding means L18C and a parameter holding means R28C, respectively. Owing to this, even if a device body shakes when imaging, suitable vibration-proof actions is taken to the optical system L and the optical system R, and as a result, the image blurring quantity of an object image obtained by an imaging element L12 is made nearly identical to the image blurring quantity of the object obtained by an imaging element R22. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
