Patent ID: 7590338

Claim:
An anti-shake apparatus of a photographing apparatus, comprising: a photometric switch that is manipulated to perform a photometric operation; a release switch that is manipulated to perform a photographing operation; a controller that performs said photographing operation without an anti-shake operation when said release switch is set to an ON state and when it is determined that either a first elapsed time from a time when a main power supply is set to an ON state does not exceed a first time, or a second elapsed time from a time when the photometric switch is set to a ON state for said photometric operation does not exceed a second time; an angular velocity sensor that is used to calculate a hand-shake quantity for said anti-shake operation; and a high-pass filter that reduces a low frequency component of an output from said angular velocity sensor, said first time being equal to a length of a charging period of said high-pass filter, said second time being equal to an interval preceding a convergence of a variance between a real reference value for a high-pass filter operation of said high-pass filter and an ideal reference value for the high-pass filter operation of said high-pass filter, an occurrence of the variance being based on a drift effect.
