    • PURPOSE: Optimized human presence detection through elimination of background interference, which is related to a frame differencing technique for eliminating background interference in a human presence detection system employed in a vehicle for proper airbag deployment. CONSTITUTION: An imaging system(50) includes a digital signal processor (DSP)(52). The DSP(52) includes the face recognition software and ranging functions that performs the analysis on the image generated by the camera(34). A clock generator(60) provides timing for the various digital devices in the system(50), and a power management system(62) provides the power. The DSP(52) is connected to a CMOS chip(70) including a pixel array(72) that represents the IR detector, such as the camera. In this example, the pixel array(72) includes 256x256 pixels to provide the desired level of resolution. The CMOS chip(70) also includes various elements for timing and control purposes, including state matching logic(74), clock/timing circuitry(76), analog conditioning circuit(78), registers/buffers(80), on-chip programmable logic circuitry(82), etc. Additionally, an analog-to-digital converter(84) is also provided to convert the analog signal from the pixel array(72) to a representative digital signal. An on-chip SRAM memory(86) is shown for storage purposes, but is off-chip as well.

    • A vehicle occupant airbag deployment system (50) that detects, identifies and tracks a person (16) in the passenger seat (18) of a vehicle (12), and provides a signal for no fire, soft fire or hard fire of the airbag (20) depending on the location of the person (16) in a crash event. The airbag deployment system (50) employs infrared emitters (30) that emit an infrared signal towards the passenger seat (18) of the vehicle (12) and an infrared detector (34) that receive reflected radiation from objects in the seat (18). Processing circuitry (52), including face recognition software, is employed to detect human face features to provide the necessary detection and tracking of the person (16). In this manner, the system (50) prevents the airbag (20) from firing if the seat (18) is not occupied by a person (16), prevents the airbag (20) from firing if a person (16) is detected, but is too close to the airbag (20), and provides a soft fire if a person (16) is detected, but is within a soft fire range of the airbag (20).
