Estimating the term…
An optical lens assembly is disclosed as including a light-sensitive member; first and second lenses/lens groups with their respective optical axis aligned with each other along a common optical axis; and first and second piezo electric ultrasonic linear motors; in which the first motor is operable to move the first and second lenses/lens groups relative to each other to vary their distance; and the second motor is operable to move the light-sensitive member or at least one of the first and second lenses/lens groups to vary the distance between the light-sensitive member and the lens/lens group. A handheld electronic device, e.g. a mobile phone or a personal digital assistant, with digital camera function, and including such an optical lens assembly is also disclosed. There is further disclosed an optical lens system including an optical system, a light-sensitive component, an auto-focus judge for determining if an image captured by the light-sensitive component is in focus, and a driving IC for driving a piezo electric ultrasonic linear motor in response to the result arrived at by the auto-focus judge.
An optical lens assembly including:
A handheld electronic device with digital camera function, said device including an optical lens assembly, said lens assembly including at least one light-sensitive member;
An optical lens assembly including:
A handheld electronic device with digital camera function, said device including an optical lens assembly, said lens assembly including at least one lens/lens group;
An optical lens system including an optical system, a light-sensitive component, means for determining if an image captured by said light-sensitive component is in focus, and means for driving a piezo electric ultrasonic linear motor in response to the result arrived at by said determining means.
