ABSTRACT:
In a digital camera having multiple optical systems, multiple image capturing elements are effectively driven to reduce power consumption. A digital camera has a first image capturing optical system having a lens and a first image sensor and a second image capturing optical system having a lens and a second image sensor. A controller and timing generator selects the image signal from the first image capturing optical system while controlling an operation or power of the second image sensor and a clock driver to be OFF when the zoom position falls within a first zoom range. When the zoom position falls within a second zoom range, the image signal from the second image capturing optical system is selected while an operation or power of the first image sensor and a clock driver is controlled to be OFF. An operation or power of the image capturing optical system which is not selected is stopped so that power consumption is reduced.
