Abstract

Disclosed is a micro mode executing apparatus of a digital still camera using a focus driving motor, in which an image sensor and a focus controlling lens are connected to a focus driving motor and a spindle of the motor, thereby controlling an optical length within a range of not changing a barrel structure. The micro mode executing apparatus comprises a motor, an image sensor, a focus lens, a housing, a first biasing member, and a second biasing member.

Description

technical field [0001] The present invention relates to electronic still life cameras. In particular, it relates to a micro-drive device for a digital still image camera using a focus drive motor, which connects an image converter and a lens for adjusting focus to the axis of a focus drive motor and an equivalent drive motor, so as to adjust the depth of field without changing the structure of the lens barrel . Background technique [0002] Recently, a variety of electronic still cameras have been developed that use still pictures as conversion image signals and record them on disks. This kind of electronic still cameras is the same as the cameras that usually use silver salt films, by moving the focus circle of the imaging lens to adjust focus point. [0003] At this time, there is an example of automatic focusing by an automatic focusing device. This kind of automatic focus device uses a certain method to detect the distance between the camera and the object to be illum...
