Camera module and optical device comprising same

Abstract

An embodiment comprises: a lens module; a first optical path change part including an incident surface and an emitting surface, and reflecting light, which is incident onto the incident surface, to emit the light via the emitting surface; and a second optical path change part including a first surface which faces the emitting surface in an optical axis direction of the lens module and a second surface which is an opposite surface to the first surface, wherein, in order to change the path of light emitted via the emitting surface, the first optical path change part is tilted or rotated about a first axis perpendicular to the optical axis direction, and, in order to change the path of light emitted from the second surface, the second optical path change part is tilted or rotated about a second axis perpendicular to the optical axis direction and the first axis.

Description

technical field [0001] Embodiments relate to a camera module and an optical device including the camera module. Background technique [0002] It is difficult to apply voice coil motor (VCM) technology used in existing general-purpose camera modules to miniaturized low-power camera modules, and related research has been actively conducted. [0003] In a case where the camera module is configured to be mounted in a small electronic product such as a smartphone, the camera module may often be subjected to shocks during use, and may be subjected to fine shaking due to, for example, shaking of a user's hand. In consideration of this, a technology has been developed that enables a device for preventing hand shake to be additionally mounted to the camera module. Contents of the invention [0004] technical problem [0005] Embodiments provide a camera module capable of reducing the amount of space or size required to implement an OIS operation and an optical apparatus including...
