  • Publication number: 20220309692
    Abstract: The present disclosure relates to a distance measurement apparatus and a biometric authentication apparatus that are capable of conducting high-precise distance measurement even in intense light such as sunlight. A light source applies light to a subject. An image sensor captures an image of the subject. A distance measurement section calculates a distance to the subject on the basis of the image obtained by the image capturing. A transparent member is formed, on the image sensor, so as to be integrated with the image sensor. In addition, the transparent member includes a transmission film that allows a peak wavelength band of the light of the light source to transmit therethrough. The present disclosure is applicable to a biometric authentication apparatus, for example.

  • Patent number: 11444622
    Abstract: A proximity sensor that detects the distance between two coils is disclosed. In one example, the proximity sensor includes a reference signal generation circuit, a first coil, a second coil, a clock signal generation circuit, and a switched capacitor circuit. The reference signal generation circuit applies a first alternating voltage to the first coil and transmits a reference signal synchronized with the first alternating voltage to the clock signal generation circuit. The second coil is coupled with the first coil by magnetic field coupling to generate a second alternating voltage correlated with a coupling coefficient. The clock signal generation circuit transmits clock signals corresponding to the reference signal to the switched capacitor circuit, and the switched capacitor circuit detects a distance between the first coil and the second coil by acquiring the second alternating voltage at a timing when each of the clock signals changes.
