Abstract
A preprocessing method and a preprocessing system for improving image recognition are provided. The preprocessing method includes the following steps: disposing light-emitting diodes to surround an image sensor, in which the image sensor corresponds to an image capture region; turning on the light-emitting diodes for emitting a white light source having a color temperature of 3200K, in which the white light source has a fixed illumination area range, and the illumination area range covers the image capture region, such that a color temperature of the image capture region is approximately or equal to 3200K; and turning off the light-emitting diodes for a time interval, such that the image sensor captures images to generate preprocessing frames under a low illuminance condition that is between 0.0004 lux and 1 lux.
