Problems solved by technology

However, dual camera modules have disadvantages when two independent camera modules are arranged adjacently because of mutual magnetic interference on the two independent camera modules
[0005] In addition, unwanted light is often incident on the image sensor by reflecting from the interior of the camera module, thereby disadvantageously producing a flare phenomenon

Embodiment Construction

[0125] Some exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In describing the reference numerals used for each element, the same elements will be assigned the same reference numerals if possible, although they are indicated differently in other drawings.

[0126] In describing elements in the exemplary embodiments of the present invention, the terms first, second, A, B, (a), (b), etc. may be used. These terms may be used only to distinguish one element from another element, but the nature, order or sequence are not limited by these terms. When an element is referred to as being "proximate to", "coupled to" or "connected to" another element, it will be understood that the element may be directly adjacent to, directly connected to or directly coupled to the other element or intervening elements may be present therebetween.

[0127] The term "optical axis direction" used hereinafter may be defined as the opt...

Abstract

The present embodiment relates to a dual lens drive device that comprises: a housing; a first bobbin which is disposed to move in a first direction inside the housing; a second bobbin which is disposed to move in the first direction inside the housing and is spaced apart from the first bobbin; a first coil which is disposed on the first bobbin; a second coil which is disposed on the second bobbin;a magnet which is disposed in the housing and faces the first coil and the second coil; a base which is disposed below the housing; a substrate which comprises a circuit member having a third coil disposed to face the magnet between the housing and the base; and a support member which movably supports the housing with respect to the substrate, wherein the housing is integrally formed.

Description

technical field [0001] The invention relates to a dual-lens driving module, a dual-camera module and an optical device. Background technique [0002] This section provides background information related to the present disclosure which is not necessarily prior art. [0003] Along with the promotion of widespread use of various mobile terminals and the commercialization of wireless Internet services, consumer demands related to mobile terminals have also diversified to allow various types of peripheral devices to be mounted on mobile terminals. [0004] Among the representative items of peripherals, a camera module that captures a subject in a picture or video is mentioned. Meanwhile, recently, active research has been conducted on a dual camera module in which two independent camera modules are adjacently arranged. However, the dual camera module has disadvantages when two independent camera modules are arranged adjacently because mutual magnetic interference may be generat...
