Abstract: In an image stabilization control circuit for an image capturing device, a gyro-equalizer (24) is used to integrate an angular velocity signal corresponding to vibration, and determine a required magnitude of lens displacement. The gyro-equalizer (24) integrates the angular velocity signal from a gyro-sensor (12) using an integration circuit (46) (LPF), and converts the signal into an angular signal. A direct current component of the angular signal is removed using a centering circuit (50) (HPF). The LPF and HPF can produce an insufficient phase delay in a low-band side of a target compensation region. A phase lag compensation circuit (48) comprising a low-boost filter compensates for the insufficient phase delay, and brings the phase delay of the angular signal with respect to the angular velocity signal close to 90° in an integration process.
