Apparatus and method for processing physiological signal

A physiological signal processing apparatus, comprising:

• a light source module capable of emitting a mixed light beam on a light guide panel for a finger to touch, wherein said light source module is disposed opposite to where said finger touches said light guide panel and said mixed light beam comprises a plurality of colored light beams;
• a light control module coupled to said light source module and controlling said light source module to emit said mixed light beam;
• an image sensing module sensing said mixed light beam reflected by said light guide panel to provide an image signal of said finger;
• and
• an analyzing module coupled to said image sensing module and analyzing said image signal extracted by any of said plurality of colored light beams to acquire a plurality of physiological signals.

A physiological signal processing method applicable to a physiological signal processing apparatus, said physiological signal processing apparatus comprising an image sensing module, said method comprising the steps of:

• emitting at least one first light beam and at least one second light beam;
• sensing an image signal of a finger on a light guide panel of said physiological signal processing apparatus by said image sensing module, said image signal being provided by said first light beam and said second light beam being reflected;
• and
• analyzing said image signal to acquire at least one first physiological signal and at least one second physiological signal, wherein said first physiological signal is different from said second physiological signal.
