Image blurring correction device and imaging device using the same with a high pass filter

Abstract

An imaging device includes an angular velocity sensor (), which outputs a blurring signal, a high-pass filter circuit unit (), which eliminates a direct current component in accordance with a first time constant, and which outputs a fluctuation portion with respect to a reference voltage as an angular velocity signal, an analog switch ASW (), which cause a charge that is accumulated within the high-pass filter circuit unit () to discharge according to a second time constant, a computation unit (), which is for performing a computation in order to correct a blurring of an image in accordance with the angular velocity signal, and a detection circuit unit (D), which, in order to detect a change over time of the angular velocity of the camera body, samples the angular velocity signal on a per fixed time interval basis, obtains a derivative in accordance with a value thus sampled of the angular velocity signal, and detects a change over time in a size of the derivative thus obtained, wherein the time constant of the high-pass filter is switched between the first time constant and the second time constant of the high-pass filter by controlling a switching on or off of the analog switch in accordance with the result of the detection that is performed by the detection circuit unit (D).
