  • Patent number: 12363435
    Abstract: An image sensor stabilizer includes a lower frame, an upper frame on the lower frame and supporting an image sensor, a first actuator and a second actuator between the lower frame and the upper frame and is configured to drive the upper frame to move in a first direction relative to the lower frame, a third actuator between the lower frame and the upper frame and configured to drive the upper frame to move in a second direction relative to the lower frame, and a guide ball between the lower frame and the upper frame. The first actuator and the second actuator are spaced apart from each other in the second direction. The image sensor stabilizer can be used in a camera module.

  • Publication number: 20250071424
    Abstract: A camera module and an electronic device include the camera module having a first lens group including at least one lens, a reflection member configured such that light incident from the first lens group in a first direction is reflected by the reflection member in a second direction crossing the first direction, a second lens group arranged in the second direction and including at least three lenses, and an image sensor configured to receive an optical signal passing through the second lens group and generate an electrical signal related to an image based on the optical signal, wherein the camera module satisfies 1.2<|f1/f|<3, where f1 refers to a focal length of the first lens group, and f refers to a total focal length of an optical system including the first lens group and the second lens group.
