摘要： The present invention relates to an apparatus and a method for controlling auto focus of a camera module including a voice coil motor actuator. The camera module includes a sensing unit configured to sense a movement of the lens unit and a controller configured to control the movement of the lens unit based on a sensing signal sensed by the sensing unit. If an initial operation command is received, the controller moves the lens unit to an end point of a maximum movement range. If the lens unit is positioned at the end point of the maximum movement range, the controller compares the sensing signal sensed by the sensing unit with a predetermined reference signal to calculate a compensation value for an error. If a focus operation command is received, the controller can move the lens unit to a focus position based on the calculated compensation value and compensate for the focus position of the lens unit.

摘要： The present disclosure relates to an imaging lens, a camera module and an electronic device including the same. The imaging lens according to an embodiment of the present disclosure includes a catadioptric lens on which light is incident from an object side, and through which light is reflected and emitted from the inside; and a lens group including a plurality of lenses for transmitting the light emitted from the catadioptric lens to an image surface, wherein the catadioptric lens includes: an incident surface on which light is incident from the object side; a second mirror surface which is formed concave toward the object side, and reflects the light incident on the incident surface to a first mirror surface in the object side; the first mirror surface which is formed, at a central portion of the incident surface, convex toward an image side, and reflects the light reflected from the second mirror surface toward the image side; and an exit surface through which the light reflected from the first mirror surface is emitted, wherein all of the lens group is disposed between the first mirror surface and the second mirror surface based on an optical axis. Accordingly, it is possible to increase the brightness of the lens, increase resolution, suppress an increase in thickness, and reduce tolerance due to mirror assembly.
