The first lens element has an object-side surface being convex in a paraxial region thereof. The second lens element has negative refractive power. At least one lens element has an inflection point. A focal length of the image capturing lens system is varied by changing axial distances between the three lens groups in a zooming process. The image capturing lens system has a long-focal-length end and a short-focal-length end. The second lens group is moved relative to the first lens group along an optical axis in the zooming process.

A mobile terminal includes a memory; a touch screen; a first camera having a first capturing angle; a second camera having a second capturing angle that is wider than the first capturing angle; and a controller. The controller is configured to: cause the touch screen to display a first preview image of the first camera, a second preview image of the second camera, or both the first and second preview images overlapping each other; cause the memory to store a first image taken by the first camera in response to a first capture command received while the first preview image is displayed; and cause the memory to store both the first image and a second image taken by the second camera when a wide-angle capturing condition is satisfied while at least one of the first preview image or the second preview image is displayed.

The present embodiment relates to a dual camera module comprising: a first camera module including a first liquid lens and capturing a first image; and a second camera module including a second liquid lens and capturing a second image, wherein a viewing angle of the first camera module is smaller than a viewing angle of the second camera module, at least a part of the viewing angle of the first camera module is included in the viewing angle of the second camera module such that there is an overlapping area between the first image and the second image so as to enable a composite image formed by combining the first image and the second image to be generated, and when the first camera module is focused, a focal length of the first liquid lens is varied according to the distance between the first liquid lens and a subject, and when the second camera module is focused, a focal length of the second liquid lens is varied according to the distance between the second liquid lens and the subject.

A vibratory actuator control apparatus includes a vibrating member, having an electro-mechanical energy conversion element, and a contact member that contacts the vibrating member. In a second case where the vibrating member and the contact member are brought from a stationary state to a stopped state, an operation sequentially passes through a third stage and a fourth stage. The third stage is for decelerating a relative movement driving speed by applying a driving voltage to the electro-mechanical energy conversion element while maintaining a control parameter of the driving voltage constant and increasing a driving frequency. The fourth stage is for decelerating the driving speed by applying the driving voltage to the electro-mechanical energy conversion element while maintaining the driving frequency constant and decreasing the control parameter of the driving voltage. A start frequency is set based on the driving frequency corresponding to a predetermined driving speed in the third stage.

The lower spring is elastically provided between the base and the lens unit. The lens unit is movably provided on the base relative to the base. The upper spring is provided on the lens unit. The coil is provided on the lens unit. The magnet is arranged corresponding to the coil. One end of the terminal is exposed from a bottom portion of the base, and the other end extends toward the upper spring to be electrically connected to the upper spring. The upper spring is also electrically connected to the coil.

A lens apparatus includes an urging member disposed between first and second lens holding members, a first guide member including a first receiver configured to receive the urging member, and a first guide protrusion extending in an optical axis direction from the first receiver toward the second lens holding member, and a second guide member including a second receiver configured to receive the urging member; and a second guide protrusion extending in the optical axis direction from the second receiver toward the first lens holding member.
