Abstract: An optical system and a method for eliminating misjudgment of reflective lights are provided. The method includes: emitting a detection light by a light source; receiving reflective light signals by a light sensor; and configuring a processing circuit to: generate a characteristic pattern according to the reflective light signals received by the light sensor; analyze the characteristic pattern and determine whether or not the characteristic pattern includes a plurality of sub-patterns; in response to determining that the characteristic pattern includes the plurality of sub-patterns, compare positions of the sub-patterns with a reference position of a reference pattern; and select the sub-pattern having the position that is closest to the reference position to determine whether an object possesses and eliminate misjudgment caused by the reflective lights.

Abstract: A liquid providing system of detecting a target container includes a main body, a holder, an optical sensor and an operational processor. The main body has a supporting platform. The holder is disposed on the supporting platform, and the holder is made by low reflectivity material and adapted to hold the target container. The optical sensor is disposed above the supporting platform and adapted to output a detection image containing the target container and the holder. The operational processor is 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.
