The present invention relates to a camera module inspection device, and the camera module inspection device of the present invention is characterized by comprising: a socket part for mounting a camera module; a mobile unit pattern chart lens unit including a housing, a light source unit that irradiates light toward the camera module inside the housing, and a chart that is disposed below the light source unit inside the housing and on which a unit pattern is formed; a first driving unit for driving the mobile unit pattern chart lens unit; the second driving part is used for driving the socket part; and an inspection image acquisition section for obtaining an overall inspection image of the image sensor by integrating images of the unit pattern captured while the mobile unit pattern chart lens section or the receptacle section is driven by the first driving section or the second driving section.
Description
technical field [0001] The present invention relates to a camera module inspection device, and more specifically, to a camera module inspection device capable of inspecting the resolution and the like of a camera module mounted on a portable terminal or the like. Background technique [0002] Portable terminals such as mobile phones and tablet computers are usually equipped with camera modules in order to perform additional functions such as taking pictures or shooting videos in addition to their inherent functions. Recently, with the development of technology, camera modules are developing toward ultra-small, high-resolution, and high-pixel. [0003] The camera module is composed of an image sensor such as a charge-coupled device (CCD, Charge Coupled Device) or a complementary metal-oxide semiconductor (CMOS, Complementary Metal-Oxide Semiconductor), and a lens mounted in front of the image sensor. Before the camera module is shipped, Various checks are performed to confir...
