发明名称 IMAGING DEVICE AND CONTROL METHOD THEREFOR
摘要 <P>PROBLEM TO BE SOLVED: To control timing of an output change relating to amplification of a blurring detection signal of an imaging device so as to minimize a shift of an image caused by the output change. <P>SOLUTION: A detection signal of an angular velocity sensor 102 includes an offset component in a static state of an imaging device 100, and is transmitted to an A/D converter 104 after being amplified by a summing amplifier 103. An offset component computing part 105 calculates the offset component and outputs it to a subtractor 106. Drive of a corrective optical system 119 is controlled in accordance with a blurring correction amount calculated by a focus distance computing part 112. When the offset component calculated by the offset component computing part 105 exceeds a threshold, and a change of the output from the offset component computing part 105 has no influence on a taken image, a voltage control part 126 changes output from a D/A converter 108 so as to prevent the output after amplification to a variation in the offset component from being saturated, and changes the output from the offset component computing part 105 in accordance with the change. <P>COPYRIGHT: (C)2012,JPO&INPIT
