摘要：
A method for dynamically adjusting fluorescent imaging is provided. The method is used in a device and includes the following steps: emitting, by a light emitting diode, light to illuminate teeth in an oral cavity, wherein the light is used to generate fluorescence from the teeth； filtering, by an optical filter, the fluorescence； receiving, by an image sensor, a signal and adjusting a gain value of an analog-to-digital converter according to the signal； converting, by the analog-to-digital converter, the filtered fluorescence into a digital signal and adjusting the digital signal according to the gain value； and generating, by a processor, an output image signal that corresponds to the gain value from the digital signal.
