Abstract
An identifying method for detecting a specific region of a translucent medium provided includes steps as follows. A light sensing module is adjusted to allow an operation point of the light sensing module to be in an active region. Light is emitted to a driven translucent medium by a light-emitting module. The light been passed through the translucent medium is sensed by the light sensing module to generate a first light-intensity signal based on the light sensed at one time instant, and the voltages of the first light-intensity signal are regulated to derive a second light-intensity signal. A voltage level of the first light-intensity signal is compared with that of the second light-intensity signal to generate a comparison result. A determination of whether a specific region of the translucent medium is positioned between light sensing module and light-emitting module is made based on the comparison result.
