Abstract
The present disclosure relates to a distance measuring device and a distance measuring method enabling use of a plurality of sensors employing different distance measurement schemes in combination at low cost. A pixel region including a pixel including a SPAD to be used for distance measurement using a direct ToF scheme and a pixel including a current assisted photonic demodulator (CAPD) to be used for distance measurement using an indirect ToF scheme or a normal pixel, and a light emitting unit are shared and controlled. The present disclosure can be applied to a distance measuring device.
Claims20
A distance measuring device comprising:
- a light emitting unit configured to emit distance measurement light;
- a pixel region including a first pixel to be used for distance measurement using a first time of flight (ToF) scheme and a second pixel to be used for distance measurement using a second ToF scheme;
- and
- a control unit configured to control the first pixel, the second pixel, and the light emitting unit.
A distance measuring method of a distance measuring device including:
- a light emitting unit configured to emit distance measurement light;
- a pixel region including a first pixel to be used for distance measurement using a first time of flight (ToF) scheme and a second pixel to be used for distance measurement using a second ToF scheme;
- and
- a control unit configured to control the first pixel, the second pixel, and the light emitting unit,
- the distance measuring method comprising:
- a step of the control unit controlling the first pixel, the second pixel, and the light emitting unit.
