Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application claims the benefit under 35 USC § 119(a) of Korean Patent Application No. 10-2024-0157472 filed on Nov. 7, 2024, in the Korean Intellectual Property Office the entire disclosure of which is incorporated herein by reference for all purposes. BACKGROUND 1. Field The following description relates to a camera module. 2. Description of Related Art With the recent trend toward the miniaturizing and the slimming down of the form factor of portable electronic devices, such as mobile phones, there has been a continuing effort to reduce sizes of components that are mounted in the electronic devices. Additionally, technologies that integrate various operations of the electronic components are being implemented. Camera modules, which is one of the electronic components, may be implemented for smartphones, notebook computers, and vehicles, as only examples. With the increase in videography, the use of camera modules in portable smartphones has increased. Additionally, high-performance camera modules are also disposed in vehicles to implement a cutting-edge advanced driver assistance system (ADAS) to enable autonomous driving operations. However, as the camera module has been highly pixelated and miniaturized, there is an increasing concern that the camera module may be damaged by forces applied from the outside. SUMMARY This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter. In a general aspect, a camera module includes a lens barrel; a carrier configured to accommodate the lens barrel; an image sensor disposed to face the lens barrel in an optical axis direction; a substrate electrically connected to the image sensor; and a sub-housing having a light transmission hole, and disposed between the lens barrel and the substrate, and configured to support an optical filter, wherein the sub-housing includes a filter support part positioned in an inner region of the sub-housing adjoining the light transmission hole; and an outer collision mitigation part that protrudes further upward in the optical axis direction than the filter support part, and wherein the outer collision mitigation part is positioned to face the carrier in the optical axis direction.
