There is disclosed a camera capable of display a moving image, which executes auto focusing of a hill-climbing system while executing a blur correcting operation to reduce image blur generated by vibration applied to the camera. Examples of the blur correcting operation include a correcting operation by a mechanical blur correction mechanism which moves an image pickup device so as to cancel the vibration, and a correcting operation of electronic image blur correction to obtain a video signal which does not have any image blur from an output of the image pickup device by processing an image.
