TIME OF FLIGHT CAMERA DEVICE AND METHOD OF DRIVING THE SAME |
| 摘要 |
A time of flight (TOF) camera device and a method of driving the same are provided. The TOF camera device includes a pulse generator configured to generate a pulse signal, and generate a first photo gate signal and a second photo gate signal; a light source configured to irradiate an object with light emitted in synchronization with the pulse signal; and an image sensor configured to receive light reflected from the object in synchronization with the first photo gate signal during a first frame, and receive light reflected from the object in synchronization with the second photo gate signal during a second frame. The pulse generator is further configured to modulate the pulse signal so as to use a frequency of the light as a single frequency. |

1. A time of flight camera device comprising:
a pulse generator configured to generate a pulse signal, a first photo gate signal and a second photo gate signal; a light source configured to emit light in synchronization with the pulse signal to irradiate an object with the light; and an image sensor configured to receive light reflected from the object in synchronization with the first photo gate signal during a first frame, and receive the light reflected from the object in synchronization with the second photo gate signal during a second frame, wherein the pulse generator is configured to modulate the pulse signal so as to use a frequency of the light as a single frequency. |
