The invention relates to a method for selecting an image data source in an optical instrument, which comprises the following steps of: a, providing an image processing device, and capturing an image data source from an optical sensor; b, detecting and filtering intrinsic noise signals contained in the image data source; c, extracting the exposure time Te of image data after the intrinsic noise signals are removed and calculating the gray average value RTH of the image data by the image processing device; and d, when the obtained image data exposure time Te is smaller than the set time TH1 or the gray average value RTH of the image data is greater than a set value TH2, enhancing the contrast of the image data by the image processing device. The method provides accurate positioning for subsequent image processing, reduces the processing time of the image data, improves the accuracy of image data processing, has simple processes, and is safe and reliable.
