PROBLEM TO BE SOLVED: To provide an electronic camera capable of suppressing image disturbance caused by a noise generated from a power supply circuit. SOLUTION: The electronic camera includes an imaging element, a timing generator, a power supply circuit, a temperature detection part, a memory, an operation part, and a driving frequency control part. The imaging element photoelectrically converts an object image and outputs an image signal. The timing generator supplies a drive signal for driving the imaging element. The power supply circuit supplies power. The temperature detection part detects a temperature of the power supply circuit. The memory stores information indicating correspondence relation between a frequency of a noise generated due to the operation of the power supply circuit and a temperature. The operation part estimates the frequency of the noise on the basis of the detection result of the temperature detection part and the information indicating the correspondence relation. The driving frequency control part changes the driving frequency of the drive signal according to the noise frequency estimated by the operation part. COPYRIGHT: (C)2010,JPO&INPIT
