摘要： A shading correcting method for a real-time image is disclosed and includes following steps: obtaining a real-time image through an image sensor; reading a stored previous image which is time-adjacent to the real-time image; computing an image reference data of the previous image; computing an adjusting parameter in accordance with the image referring data and an equipment reference data of the image sensor; adjusting a gain table based on the adjusting parameter to generate an adjusted gain table, wherein the gain table records multiple compensation values each for compensating each corresponding pixel of the real-time image; correcting the real-time image in accordance with the adjusted gain table to generate an adjusted image; and, outputting the adjusted image.
