An image sensor module having a defocus calibration function is provided to save time and costs for exchanging, assembling, disassembling, or removing of parts by calibrating deviation of a tangential line of an image sensor installation plane from an optical axis of a lens. An image sensor module having a defocus calibration function includes a barrel(132), a housing(142), and a sensor unit(154). The barrel has a main body and a protrusion unit. A lens is mounted on a main body of a housing shape. The protrusion unit is extended to the outside of a radius direction from an upper end of the main body. The housing receives a lower part of the barrel. A plurality of screw holders are formed corresponding to the protrusion unit. The sensor unit has an image sensor installed on an upper plane of a substrate in correspondence to the substrate coupled to a lower end of the housing and the lens installed on the barrel. When a screw is inserted into one of the screw holders, focusing deviation between the lens and the image sensor is compensated by rotating the barrel with respect to an axis of the housing. |
