Colorimeter module capable of real time zero calibration, and color meter using same

Disclosed are a colorimeter module, and a color meter using the same, the colorimeter module comprising: a main sensing unit including a light sensing part for receiving light introduced from a light entrance lens so as to generate current according to a color, and a first measuring part for measuring first current generated from the light sensing part; a sub sensing unit arranged adjacently to the main sensing unit, and including a dark sensing part for blocking light so as to generate current in a dark state and a second measuring part for measuring second current generated from the dark sensing part; a leakage measuring unit including a charging part provided to the second measuring part so as to be charged with preset current, and measuring third current leaked from the charging part; and a control unit for correcting the first current by reflecting the second current measured by the sub sensing unit and the third current measured by the leakage measuring unit, wherein, in the charging part, the current charged is reduced and the third current leaks from the charging part with a lapse of time in which the main sensing unit and the sub sensing unit receive light to generate the first current.
