1. A camera module comprising:
a housing comprising an opening and configured to accommodate an optical path conversion unit and a lens module;
a shielding member configured to shield the opening of the housing, the shielding member including a section that extends between an exit surface of the optical path conversion unit and a front of the lens module and a section that extends between an end of the lens module and an image sensor;
a reflection reducing member disposed on at least a portion of an inner surface of the section of the shielding member that extends between the exit surface of the optical path conversion unit and the front of the lens module and a portion of an inner surface of the section of the shielding member that extends between the end of the lens module and the image sensor, and configured to reduce internal reflections from the inner surface of the shielding member occurring between the exit surface of the optical path conversion unit and the front of the lens module and between the end of the lens module and the image sensor; and
a second driving unit configured to move the optical path conversion unit in a direction intersecting an optical axis of the lens module,
wherein a distance from the end of the lens module to the image sensor is greater than a distance from the exit surface of the optical path conversion unit to the front of the lens module, and
wherein a thickness of the reflection reducing member disposed on the portion of the inner surface of the section of the shielding member that extends between the end of the lens module and the image sensor is greater than a thickness of the reflection reducing member disposed on the portion of the inner surface of the section of the shielding member that extends between the exit surface of the optical path conversion unit and the front of the lens module.
