First Claim
Patent Images
1. A remote controller configured to detect and output a physiological characteristic of a finger and a control signal, the remote controller comprising:
- a plurality of press buttons configured to trigger the control signal;
a first light source providing light of a first wavelength to the finger;
a second light source providing light of a second wavelength to the finger;
a light control unit configured to control on-states of the first light source and the second light source;
at least one image sensor receiving reflected light from the finger at a sampling frequency to generate a plurality of first image frames corresponding to the on-states of the first light source and a plurality of second image frames corresponding to the on-states of the second light source; and
a processing unit configured to calculate the physiological characteristic according to the first image frames and the second image frames, and to generate the control signal according to an operating state of the press buttons.
