Abstract: An operation part calculates a shake amount of an imaging apparatus in accordance with a first operation system or a second operation system on the basis of an output signal of a sensor detecting an acceleration or angular velocity to determine a camera-shake correction amount correcting the shake amount. The operation part calculates the output signal of the sensor or a value obtained by integrating an integrated signal of the output signal of the sensor as a shake amount. The operation part includes an imperfect integrator. An operation system setting part sets an operation system of the operation part on the basis of the shake amount calculated by the operation part. In the second operation system, the operation system setting part increases a cut-off frequency of the imperfect integrator more than in the first operation system.

Abstract: The invention provides a temperature-compensating circuit which comprises first degree and second degree temperature-coefficient-generating circuits respectively comprising an operational amplifier and a plurality of resistors each having different temperature coefficient, a sign-inverting circuit, and first degree and second degree temperature-coefficient-adjusting circuits. Resistance values of the resistors of the first degree and second degree temperature-coefficient-generating circuits are decided so that voltage amplification factors are linearly or quadratically changed as a temperature changes. The sign-inverting circuit inverts signs of temperature coefficients generated by the first degree and second degree temperature-coefficient-generating circuits and the first degree and second degree temperature-coefficient-adjusting circuits adjust temperature coefficients generated by the first degree and second degree temperature-coefficient-generating circuits to predetermined values.
