Low Power Door-Lock Apparatus Based On Battery Using Face Recognition
First Claim
1. A door-lock apparatus based on a battery, comprising:
- a complementary metal oxide semiconductor (CMOS) image sensor (CIS) configured to obtain an optical signal and to convert the obtained optical signal into a digital image signal, the CMOS image sensor attached to a front surface of the door-lock apparatus;
an image signal processor (ISP) configured to process the digital image signal to generate image data;
a detector configured to be activated according to an operation of the ISP and to detect information about an object from the image data;
a memory configured to store and maintain information about a reference object;
a controller configured to compare the information about the object with the information about the reference object and to control a locking/unlocking state of the door-lock apparatus; and
a door opening and closing unit configured to be controlled by the controller and to convert the door-lock apparatus from the locking state to the unlocking state.
