Abstract
The present invention provides a processing circuit applied to a face recognition system, which includes a characteristic value calculation module, a determination circuit and a threshold value calculation module. The characteristic value calculation module is used to receive an image and process the image to generate a specific characteristic value; when the face recognition system operates in a face recognition phase, the determination circuit calculates multiple differences each between the specific characteristic value and one of multiple reference characteristic values, and determines whether at least one of the multiple differences is lower than a threshold value to generate a determination result; and when the face recognition system operates in a face registration phase, the threshold value calculation module determines a new threshold value according to differences between the specific characteristic value and the multiple reference values, for updating the threshold value used by the determination circuit.
