This is the original description copied from the patent:
“The digital camera of the present invention has a still image shooting mode and a moving image shooting mode, and performs different focusing operations between the still image shooting mode and the moving image shooting mode.
For example, the range of focusing tolerance and the driving speed of a focusing optical system can vary between the still image shooting mode and the moving image shooting mode such as to set the range of focusing tolerance wider or the driving speed of the focusing optical system slower in the moving image shooting mode.
An exemplary structure of the present invention can be expressed as follows. A digital camera having a still image shooting mode and a moving image shooting mode comprises: a mirror member arranged in an optical path of a photographing lens to reflect part of a subject light beam passing through the photographing lens and transmit the remaining part of the subject light beam; an imaging part for receiving the subject light beam transmitted through the mirror member to output a subject image signal; a distance measurement part for receiving the subject light beam reflected by the mirror member to detect a defocus amount of the photographing lens; and a focusing part for performing a focusing operation to drive the focusing optical system in the photographing lens to an in-focus position based on the defocus amount detected by the distance measurement part, wherein in the still image shooting mode, the focusing part performs a first focusing operation prior to still image shooting, and in the moving image shooting mode, the focusing part performs a second focusing operation different in mode from the first focusing operation during moving image recording.
According to the present invention, there can be provided an easy-to-use digital camera capable of acquiring both still and moving images.”
