Imaging apparatus and image capturing method
An imaging apparatus includes a first image capturing unit that captures first image data through a first optical system, a second image capturing unit that captures second image data through a second optical system, and a mode switching unit that switches between a normal mode and a power saving and speedy capturing mode that has a lower consumed power than the normal mode. In a case of operating in the power saving and speedy capturing mode, an operation stopping unit stops the first image capturing unit and the control unit captures an image by use of the second image capturing unit. A battery remaining amount can also be detected. In a case the battery remaining amount is less than a threshold value, a display mode switching unit switches from first display mode displaying a monitored image of first image data to a second display mode displaying a monitored image of second image data.
