Method for correcting optical sensor array module through characteristic evaluation

A method for correcting an optical sensor array through characteristic evaluation, the method comprising:

• setting at least one of an exposure time, an analog gain, a digital gain and a frame rate of the optical sensor array to be a default value;
• statistically measuring a collection characteristic of the optical sensor array with the default value, according to a wavelength or an intensity of a standard light source having a predetermined characteristic value;
• calculating a planarization calibration value for planarizing a collection characteristic value of the optical sensor array according to a wavelength change of the standard light source;
• calculating a linearity calibration value for linearizing a collection characteristic value of the optical sensor array according to the intensity of the standard light source;
• and
• performing a planarization calibration and a linearity calibration on the collection characteristics of each pixel of the optical sensor array using the planarization calibration value and the linearity calibration value.
