Publication number: 20130251356Abstract: An imaging device with which the accuracy of blur correction is improved. The imaging device comprises an imaging component, a transformer circuit, a control circuit, a blur detecting sensor, a memory, and a blur correction controller. The imaging component captures a subject and outputs image data. The transformer circuit transforms a power supply voltage. The control circuit controls the transformer circuit. The blur detecting sensor detects blur. The memory stores information related to a specific frequency range. The blur correction controller performs first blur correction control based on the output of the blur detecting sensor when the frequency of the transformer circuit is outside the specific frequency range while the control circuit is performing control. The blur correction controller performs second blur correction control different from the first blur correction control, when the frequency of the transformer circuit is within the specific frequency range.Type: ApplicationFiled: March 8, 2013Publication date: September 26, 2013Applicant: Panasonic CorporationInventor: Ryuji NAKAMURA
