1. A liquid providing system of detecting a target container, the liquid providing system comprising:
a main body, having a supporting platform;
a holder disposed on the supporting platform, the holder being made by low reflectivity material and adapted to hold the target container;
an optical sensor disposed above the supporting platform and adapted to output a detection image containing the target container and the holder; and
an operational processor electrically connected to the optical sensor, and adapted to analyze the detection image and then acquire an effective feature inside the detection image for distinguishing the target container from the holder.
