Image sensor module assembly device and assembly method for the same

An image sensor module assembly device comprising:

• a device setting unit configured to assemble an image sensor module by setting an image sensor and a module lens at a first position and mounting the image sensor and the module lens, set at the first position, to a module body;
• and
• a test module configured to:
• input image data to the image sensor module;
• pre-process the data that are output from the image sensor module based on sensing the input image data;
• obtain, based on the pre-processed data, a module optical system reference value and a sensor optical system reference value;
• and
• determine whether to maintain the first position based on comparing each of the module optical system reference value and the sensor optical system reference value with a corresponding preset threshold range,
• wherein the test module is configured to obtain the sensor optical system reference value by:
• separating pixel values of unit pixels of the pre-processed data according to color channels;
• obtaining, for each color channel, a sample gain for each pixel included in a unit pixel of a corresponding color channel based on pixel values and a pixel average value of the unit pixel;
• and
• obtaining the sensor optical system reference value based on the sample gain for each pixel included in the unit pixel.
